In the mixed circle, there is a saying that there are only two kinds of hybrids in the world, one is Toyota hybrid and the other is others. This is enough to prove the recognition of Toyota THS hybrid system in the industry. Today, we will talk about the planetary gear mechanism, the core component of this world-renowned hybrid system.

Toyota THS hybrid system is mainly composed of Atkinson cycle engine, permanent magnet motor, planetary gear mechanism, generator, high-performance nickel-hydrogen battery, power control unit and power control unit.

The core of the whole system is this planetary gear mechanism, that is, the E-CVT transmission in the media population. However, although it is called a transmission, it does not have such complex mechanisms as clutches, torque converters or gear shafts in the traditional transmission system, and it is a power distribution mechanism specially prepared for hybrid vehicles (the official name of Toyota).

So what are the advantages and disadvantages of Toyota’s system, and what are the differences between them compared with other hybrid systems on the market? This article will be reflected one by one.

1. Why does Toyota develop the E-CVT transmission?

E-CVT transmission is the key to the whole hybrid system, and the original intention of all hybrid systems can actually be attributed to energy saving and emission reduction, as was Toyota’s launch of THS that year.

In the early 1990s, the words such as "sustainable development", "global warming" and "greenhouse effect" began to be known around the world. Under this background, Toyota began to study "automobile development model in the 21st century" and launched a project called "G21" (G stands for Globe 21 and stands for 21st century). Toyota Hybrid Power System (THS) also began to sprout at this stage.

In 1995, Toyota released the Prius hybrid concept car at the Tokyo Motor Show. Two years later, in 1997, Toyota’s first generation Prius hybrid car went on sale in Japan, which was Toyota’s first mass production model based on THS hybrid system and the first model born under the Toyota MC platform.

Here, Toyota’s hybrid world door is officially opened.

Second, at present, the THS hybrid system has developed to which generation, and which models are it mounted on?

As mentioned above, the core of THS system is actually the E-CVT transmission, that is, the planetary gear set, and the iterative upgrade of Toyota THS system is almost around the planetary gear set.

The first generation THS hybrid system was born in 1997, and it was first mounted on Prius. Its planetary gear set consists of three parts: sun gear, planet carrier and outer ring gear, which correspond to three power sources in turn: the engine is connected with the planet carrier; Sun gear is connected with the MG1 motor; The gear ring is connected with the MG2 motor.

Through precise and complex control, this planetary gear set can shunt the engine and use the motor to adjust the speed, so that the engine has been in an efficient working range, so as to achieve the purpose of saving fuel.

In 2003, Toyota introduced the second generation THS hybrid system, but the upgrade of the second generation THS hybrid system was mainly in the aspect of electronic control, and the structure of E-CVT transmission did not change much.

In 2009, Toyota introduced the third generation THS (officially called the second generation, but the industry prefers to call it the third generation). Compared with the second generation THS, it added another planetary row on the basis of the original planetary row. The second planetary row is connected with the gear ring of the first planetary row, the MG2 motor is connected with the sun gear, and the planet carrier is fixed, as shown below:

In this way, the second planetary row becomes the deceleration mechanism of MG2 driving motor, and the output torque is increased by reducing the rotation speed, so the third generation THS of Toyota has better power performance than the previous two generations. Not only that, because of the addition of a first-stage reducer, the cumbersome chain drive was replaced by a lighter and smaller gear drive, which greatly improved the transmission efficiency.

However, due to the limitation of planetary gear structure, the speed of MG2 driving motor is limited by the limit speed of MG1, so the speed of this system in pure electric mode cannot be very high (about 70km/h).

In order to better adapt to the development of the industry, Toyota introduced the fourth generation THS in 2015. In terms of structure, the most significant change in this upgrade is to change the planetary gear added by THS-III into a parallel shaft gear, and at the same time put the MG2 driving motor in the side position.

The obvious advantage is that the axial dimension of this system is reduced by 47mm, which is undoubtedly a technological innovation in the horizontal platform with an inch of land and gold. It can not only adapt to engines with larger displacement, but also make the power of MG2 driving motor higher.

In addition, Toyota also introduced a plug-in hybrid system based on the fourth generation THS in 2016. Its main change is to add a single clutch between the engine and the MG1 motor.

The function of the one-way clutch is that when the MG1 motor participates in the driving function (more often used for starting and generating electricity), it will not drive the engine to rotate together, and at the same time, it forms a dual-motor drive with the MG2 driving motor.

The structural diagram of this one-way clutch is as follows. The structure determines that it can only rotate in one direction.

From the year, Toyota E-CVT has gone through several iterations, as shown in the following figure:

(first generation THS)

(second generation THS)

(third generation THS)

(fourth generation THS)

In addition, there are hybrid systems applied to vertical platforms (the version code has not been found yet), such as Lexus LS and Lexus GS. Compared with the ordinary version of THS hybrid system, it connects a 4AT in series to simulate 10 gears. The result of this combination, on the one hand, is conducive to improving the speed, for example, the pure electric maximum speed of LS500h can reach 140km/h, on the other hand, it is more accelerated.

The four-wheel drive system applied to Erffa and Lexus LM is composed of an E-Four electric four-wheel drive with a separate motor in the rear axle, which is not much different from Toyota THS in structure.

At present, Toyota THS models that have been introduced into China include: Camry, Highlander, Saina, Willanda, Lei Ling, Visa, C-HR, Corolla, RAV4 Rongfang, Asia Dragon, Crown Lu Fang, Lingfang HARRIER, Yize IZOA, Erffa and Wilfa; Lexus brands include lexus ES, Lexus RX, Lexus NX, Lexus LS, Lexus UX, Lexus LM, Lexus CT, Lexus LC and Lexus GS(2016, 2014 and 2012 models).

III. Detailed explanation of E-CVT (officially called THS-II version)

3.1, structural composition

The core of E-CVT is this planetary gear set, which consists of sun gear, planetary carrier (including planetary gears) and external gear ring, which are connected with MG1 motor, engine output shaft and main reducer in turn, as shown in the following figure:

We can find that as long as the state of one mechanism is determined, the rotation of the other two mechanisms can also be determined. For example, if the external gear ring is stationary and the sun gear rotates, it will inevitably drive the planet carrier to rotate, which is the starting process of the vehicle.

Moreover, it is worth noting that the diameters and teeth numbers of the external gear, the sun gear and the planetary gear are fixed, which means that the torque of the engine will always be distributed to the sun gear and the external gear in proportion, and the specific value is about 72% to the external gear and 28% to the sun gear. Once the engine is running, this basic fact will not change.

In addition, due to the structural limitation of the planetary gear set, the gear ratio between the outer ring gear and the sun gear is 2.6, that is, when the outer ring gear rotates once, sun gear has to rotate 2.6 times. As a result, the speed of the M2 motor is limited by the limit speed of the M1 motor of 6,500 revolutions, which is only 2,500 revolutions, corresponding to the speed of the vehicle of 43 miles per hour, that is, about 70 kilometers per hour.

3.2, working mode

Toyota’s THS-II system can essentially realize a variety of working modes, one is pure electricity, the other is hybrid (both B and C in the picture below can be regarded as hybrid), and the other is kinetic energy recovery mode, which we will explain in turn from easy to difficult.

First, the pure electric mode. In the pure electric low load state, the battery drives the MG2 motor, and the power is transmitted to the front axle differential by MG2, which finally drives the wheels. However, because the outer gear ring of the planetary gear is hard connected with the M2 motor, it will also follow the rotation. At this time, the engine connected with the planetary carrier has internal resistance, and the power will be transmitted to sun gear, that is, M1 generator with smaller internal resistance through the planetary gear, so that it rotates in the opposite direction, and the generator is in a state of idling without generating electricity.

In the pure electric load state, at this time, the one-way clutch of the engine output shaft intervenes, the planet carrier remains motionless, the MG1 generator starts to act as a motor, the power is transmitted to the outer ring gear through the sun gear, and the wheel is transmitted to the front axle differential through the parallel shaft, and finally the vehicle is driven forward together with MG2.

The kinetic energy recovery mode is better understood. When the vehicle is decelerating, the wheels will drive MG2 and MG1 in turn, making them act as a generator.

Hybrid mode:

Compared with the first two working modes, the hybrid mode can reflect the essence of the whole system of E-CVT. When the motor power can no longer meet the demand, or the battery power is not enough, the engine needs to start and intervene at this time.

However, the engine of this system has no traditional starting mechanism, so at this time, the MG1 motor needs to turn from reverse rotation to forward rotation, so as to drive the planet carrier to rotate, and this speed will reach the efficient range of engine operation, and then the engine will start with fuel injection.

As we mentioned earlier, once the engine rotates, the torque of the engine will be transferred to the outer ring gear and sun gear, and at this time, the outer ring gear will transfer the power to the front axle differential coupled with it to drive the wheels together with the MG2 driving motor; Sun gear will drive the MG1 motor to generate electricity, which will be provided to the MG2 drive motor.

When we step on the accelerator deeply, or when we are at full load, there are three power flows. Except that part of the torque of the above engine drives the wheels and part of the torque drives the MG1 generator to supply power to MG2, the battery of the vehicle itself will also supply power to the MG2 motor, so that the vehicle can output the maximum power.

Another mode is in-situ power generation, in which all the engine power drives the MG1 generator to charge the battery. Perhaps some readers have found it here. Didn’t you say that as long as the engines move together, the torque must be distributed to the outer ring gear and sun gear in proportion?

(In-situ charging)

There is actually no conflict here, because in the in-situ power generation mode, the battery will supply power to the MG2 motor, provide a reverse torque, and lock the external gear ring.

3.3, control strategy

The structure of planetary gear set is not complicated, but the control unit of the whole system is difficult. After the engine starts and the system enters the hybrid, how to distribute the power?

First of all, we know that the MG1 motor can be regulated, and according to the relationship between planetary gears, the torque of engine torque distributed to the outer ring gear can be calculated. When the driver steps on the accelerator pedal, the system will judge the power required by the engine according to the accelerator opening and the SOC value of the battery. When the vehicle speed is low, most of the power of the engine will be distributed to NG1 for power generation, part of the power will be used to drive the wheels, and the rest will be supplemented by M2 motor.

When the vehicle speed is high, the engine will use most of the power to drive the wheels, and only a small part will be used to generate electricity, and the MG2 motor will assist in driving.

If the vehicle happens to be in the highest thermal efficiency range of the engine, the MG1 motor will get stuck, and the MG2 motor will idle, at this time, the power is completely provided by the engine.

From the above, we can also draw another conclusion: the engine is responsible for the main power output, which is used to maintain SOC balance and respond to the total power request; The generator is used for speed regulation, and its purpose is always to control the engine speed at the target working point; The motor is mainly responsible for supplementing the torque to ensure that the driver’s torque request is guaranteed.

IV. Advantages and Disadvantages of E-CVT

The E-CVT transmission has two advantages. First, the smoothness of driving. The planetary gear set replaces the transmission, and there will be no sense of frustration in shifting gears. At the same time, the system is simple in structure and more reliable in theory.

Secondly, this system can keep the engine in an efficient running range through the power split of planetary gear sets and the speed regulation of the motor, and make the fuel economy higher. We should know that the measured fuel consumption of the third-generation Prius was 4.3L/100km when it went on the market in 2009. It reached this fuel consumption level 10 years ago, which can be said to be ahead of the whole era.

Although the advantages are obvious, this set of E-CVT also has some inherent defects, mainly because of the restrictions brought by the gear structure. For example, the gear ratio of the planetary gear set limits the speed range of the engine, and at the same time, it needs to drive the generator to generate electricity, which cannot release all the power. Moreover, the more transmission paths of the gear set, the greater the energy loss; In the high-efficiency operation range of the engine, the power cannot be completely transmitted to the wheels, and it needs to be converted twice by charging or electric drive.

5. What is the current reputation of E-CVT?

Generally speaking, due to the special type of gearbox, E-CVT will not produce friction when working, and will not wear without friction, with better durability and low failure rate.

From the market reputation, we can also see the reliability of this system, and there are almost no complaints about the failure of E-CVT transmission, which also reflects its leading quality.

VI. Comparison of E-CVT Technology

Due to the limitation of patents, there are not many E-CVT with planetary gear sets as the core. Besides Toyota’s, the most famous one is the universal Volt dual-mode hybrid system (in fact, GM’s patent in this respect is earlier than Toyota’s), which also takes planetary gear sets as the core.

Structurally, the MG2 of the universal Volt is connected with the sun gear, the output shaft is connected with the planetary carrier, and the power is output to the wheels, while the gear ring is connected with the shell or the motor MG1 according to the actual operation. Through the combination and separation of clutches C1 and C2 and brake B1, GM Volt can realize various operation modes, as shown in the following table.

Compared with Toyota’s E-CVT, although the Volt structure of GM is similar, the direction of power split is completely different, which is also the product of Toyota’s racking their brains under the blockade of GM’s patents.

In addition, it is worth mentioning that although the Volt is more similar to Toyota’s YHS in structure, consumers compare more with Honda’s i-MMD hybrid and Toyota’s THS hybrid, so we also make a comparative analysis of them.

First of all, in terms of structure, Honda’s i-MMD system consists of engine, generator, driving motor, power separation device (E-CVT), PCU and lithium battery.

One of the key differences lies in the E-CVT. Compared with Toyota’s complex planetary gears, Honda’s i-MMD completes the power split through very few gear sets and clutches, and we have to know that one more transmission path of power leads to one more loss.

Compared with Toyota’s THS, Honda’s i-MMD is characterized by high structural flexibility, which can realize pure electricity, series, parallel, high-speed direct drive (Toyota THS can’t realize direct drive) and other modes, and its efficiency is very high.

In addition, the hybrid power of Honda i-MMD is higher than that of Toyota THS. Take the third generation Honda i-MMD as an example, its total motor power reaches 135KW, while that of Toyota THS-IV is only 53KW.

As for why Honda i-MMD uses such a high-power motor, the main reason is that Honda i-MMD hybrid system can’t switch the speed ratio at will like Toyota THS, so this system is in series mode under most working conditions, and the motor drives the vehicle. In order to ensure the power of the vehicle, only a more powerful motor can be selected.

It also has some disadvantages: the battery uses lithium battery, the motor power is higher, and the corresponding cost will be higher. At the same time, because it is limited by the speed ratio of the internal reduction gear set, the working space of the Atkinson engine in the i-MMD system that directly participates in driving the wheels is very narrow. In addition, Toyota’s THS has been verified on a large scale in the market, and its reliability has been proved.

Seven, Toyota open E-CVT patent.

At the beginning of the article, it is said that there are only two kinds of hybrids in the world, one is Toyota and the other is others. The reason for this statement is that on the one hand, Toyota THS hybrid performance is excellent and reliable, on the other hand, it has applied for comprehensive patent protection, and it is even more difficult for latecomers to enter the market.

However, due to the timeliness of the patent protection period, in 2017, Toyota announced the opening of the first batch of hybrid patents, and it can provide technology to the outside world, and hopes to cooperate with other car companies in this regard, but there are few respondents.

By 2018, Toyota expressed the patent opening more clearly, claiming that it would provide the right to use for free, including about 23,740 patents of electrification technology such as motor, electronic control and system control.

In 2019, the opening of Toyota’s patent finally ushered in the harvest. First, Toyota "sold" THS technology to Toyota’s core component supplier Keliyuan in China at a price of "US$ 1" (Keliyuan’s major shareholder is Geely, so it can be understood as selling technology to Geely in disguise). Later, it reached a THS hybrid technology transfer agreement with GAC and FAW.

At present, the first Guangzhou Automobile Chuanqi GS8 twin-engine series equipped with Toyota hybrid in its own brand has been listed. The power is a 2.0T engine independently developed by Guangzhou Automobile+Toyota THS hybrid system, and the official fuel consumption per 100 kilometers is 5.3L/ 100 kilometers. In addition, Geely’s Zhiqing Hi·X oil-electric hybrid system is also inextricably linked with it.

Summary:

Generally speaking, as the core of Toyota THS hybrid system, E-CVT transmission perfectly realizes the function of power shunting through planetary gear sets, and makes the engine always in an efficient working range by using motor speed regulation. This is indeed a revolutionary innovation, which also makes Toyota’s hybrid technology almost dominate the world, and its cumulative sales volume is close to 20 million. At present, THS hybrid has developed to the fourth generation, and its structure has approached perfection. Moreover, in the context of pure electric vehicles becoming the general trend, whether Toyota will continue to upgrade THS or improve E-CVT may require a question mark.

Xiamen International Conference Center renderings

People’s Daily Online, Beijing, September 6 (Reporter Jia Xingpeng) "Xiamen is home to five continents, and Menna is a vast expanse of water". On September 4th, the ninth meeting of BRICS leaders attracted worldwide attention was held in "Ludao" Xiamen, which brought new development opportunities to China. At the same time, Xiamen International Conference Center, the main venue of the meeting, also entered the world’s sight.

Everyone is amazed at the "high value" of the venue. No one would have thought that this finely crafted project was built by the original team of G20 Hangzhou International Expo Center, and the reconstruction time was only six months …

The original team of G20 Hangzhou main venue was built.

Back to last year, the G20 Hangzhou Summit just ended perfectly. A group of builders of the Hangzhou International Expo Center, the main venue of the G20 Hangzhou Summit, are preparing to "have a good rest for a while" and have received the renovation project of Xiamen International Conference Center, the main venue of the BRICS meeting.

Without a moment’s hesitation, the original team immediately went south and traveled from Hangzhou to Xiamen. With the help of the general contracting management experience successfully applied in the construction of the main venue of the G20 Hangzhou Summit, six months later, they transformed the Xiamen International Conference Center.

"We are tired and happy to lay a’ golden brick’ for Xiamen, a strategic fulcrum city of the Maritime Silk Road." Zhang Xiaoyong, deputy general manager of the General Contracting Company of China Construction Eighth Bureau and deputy commander of the BRICS site project, said.

BRICS leaders meet in Xiamen main meeting room

The International Conference Center, located on Xiamen Island Road, has been built for nearly 8 years, with a total construction area of 143,000 square meters and a renovation area of 30,000 square meters. "This is the hardest 30,000 square meters I have ever done." Mao Dengwen, the general contractor project manager of the BRICS site project of the China Construction Eighth Bureau General Contracting Company, said.

At the end of January this year, the design scheme was finally finalized, which means that in a very short time, they have to complete the new construction of the East Corridor, the Welcome Corridor, the Welcome Hall and the West Gate Hall of the conference room of the Fifth National Congress on the first floor, as well as the transformation of the business forum, bilateral talks, small conference hall and the main venue and state banquet hall on the second floor.

"All work can only be done in a cross way, which is the only way to ensure the construction period." However, difficulties followed. The conference hall of the Five National Congress, located in the southwest corner of the conference center, is a three-story new conference hall. It is not really a new one, but a new one after the three-story building in the original area was demolished and opened, and the sea viewing platform and tea lounge area were added to the new part, which is equivalent to twice the original area.

"It is equivalent to embedding a bigger cake on a cake with a corner cut off," Mao Dengwen described. According to the construction site, the project department extended outward and completed the three-storey main structure, which ensured the overall coordination of the exhibition center building and made it possible to "embed" the large volume.

"The difficulty of reconstruction is really much higher than that of new construction." However, the original drawings that the project department finally got are quite different from the situation on the spot. When dismantling and renovating, the water pipes are easily broken, and then a series of prescribed actions such as climbing pipes, finding water valves and solving water leakage are followed.

"Water pipe is to say, wire? This is a matter involving life safety. " Next, the project department scans the original building in three dimensions, generates a model, and uses the point cloud file to make the floor plan of each floor to guide the reconstruction construction. Bao Zhiwei, the project leader of the General Contracting Company of the Eighth Bureau, introduced it.

Welcome corridor of "Danguan Feiyu"

Use ingenuity in every corner.

"This is a window for China to show its elegance to the world, and we know that it is a great responsibility," said Chai Daoqi, the decoration project manager of the BRICS site project of China Construction Eighth Bureau. "In the decoration process, we apply ingenuity to every corner."

There is a welcoming corridor on the east and west sides of Xiamen International Conference Center, which is the "facade" of the whole venue and the place where leaders from all countries step into the venue. The promenade is named "Danguan Feiyu" and is composed of 48 zigzag copper beams. It is unique in shape and magnificent in momentum.

The "Ji" shape has a steel frame structure inside, and the copper plate is wrapped outside. "In order to ensure the accurate positioning and welding of the copper plate, the project department has carried out numerous pay-off measurements to correct the deviation, and the final structural deviation is controlled within 2 mm, which is much higher than the design standard." Chai Daoqi said.

The historical Maritime Silk Road has created a unique Haisi culture in Fujian. After passing through the welcome corridor and entering the entrance lobby, six special-shaped stone pillars come into view. The hyperbolic shape of cylindrical stone and the curved carved aluminum plate of bamboo joint on the ceiling extend each other, demonstrating the openness and tolerance of China under the "Belt and Road" initiative.

However, due to the complicated connection between special-shaped and stone materials, the project will weld the special-shaped steel frame according to the construction nodes, and continuously check the construction accuracy in the process. At the same time, in order to pursue the most perfect visual effect, they have made fine adjustments from material types, color matching, texture effect to grain direction.

We must not only ensure the grain of the cylinder, but also ensure the harmony and unity with the grain of the ground. "At that time, like obsessive-compulsive disorder, we laid 342 arc-shaped boards on the ground for pre-typesetting, but there were no flaws, no lines, and no color difference." Material engineer Wang Yufeng said. However, it is also their "obsessive-compulsive disorder" that has made the amazing scene of the integration of sea and sky in the entrance lobby.

Five-petal ceiling lantern with a diameter of 9.3m in the main conference room.

The large-scale conference room of the five countries is the most important place of the BRICS Summit. The five-petal ceiling lantern directly above is very eye-catching, with a diameter of 9.3 meters and a weight of only 180 kilograms. Sun Yinbo, a decoration engineer, explained, "The lampshade uses a new type of high-light-transmittance lightweight nano-carbon fiber board, which is very light and developed by beijing university of chemical technology, and has been applied to lamps for the first time in China."

Dehua porcelain, as one of the famous kilns in the Song Dynasty, has been made into works of art or daily necessities such as bottles, cans, cups and plates for thousands of years. On the main background wall of the conference room of the five countries, Dehua porcelain was made into the shape of the national flower of the BRICS countries and "pasted" on the wall. "We regard the famous porcelain of the Song Dynasty as’ tiles’ and we are the first people to eat crabs." Chai Daoqi said.

Since this is the first time, the project department is particularly cautious, sending special personnel to Dehua porcelain production site to inspect the local soil quality, inspect the manufacturer’s technology, and strictly stipulate the location and depth of Dehua porcelain mining soil. "The most important thing is that Dehua porcelain will shrink during the firing process. If it is not well controlled, it will be scrapped."

The decoration team of the First Company of China Construction Eighth Bureau conducted several firing tests. By controlling the temperature, humidity and temperature, the shrinkage rate of Dehua porcelain was determined, and the output rate and splicing accuracy of porcelain products were ensured.

"Dehua porcelain" on the wall

On the upper part of the wall around the conference room, there is a "colorful" copper plate. Red, blue, green, orange and yellow represent China, Russia, Brazil, South Africa and India respectively. In addition to color, this circle of copper plates has different patterns, creating a rich sense of hierarchy.

The project department repeatedly compared, confirmed and adjusted the "painted color, pattern and etched area of copper plate", and finally achieved the effect of "carving beams and painting buildings".

Even the slightest mistake can’t occur.

If the decoration project is compared to "clothes", then the installation is "blood vessels and nerves". "Now we can’t see the results of our work, but everything we do determines the function of the conference center."

Zhang Tao, the project electromechanical manager of the General Contracting Company of the Eighth Bureau of Construction, said, "The most important thing is that the complicated installation work has also encountered reconstruction projects."

The scene of sea-sky integration in the welcome hall

The pipelines of fire fighting, electric power and drainage systems in the old site need to be replaced because of the progress of the times. It is a headache to install pipelines with thick arms where one finger is thick. In addition, the installation space is too small to accommodate large equipment, so the project installation team can only manually explore the pipeline layout, measure and draw again and again, and the pipelines are finally arranged in an orderly way, laying a foundation for the normal operation of the whole building.

Zhang Tao knows that the reasonable arrangement of pipelines is only the first step. In this national conference project, the national normal installation standards are no longer applicable. If there is any-even the smallest mistake during the conference, the consequences will be "unbearable" for all participants.

In order to ensure the air, they adopt an air purification system with double purification functions of electrostatic dust removal and ultraviolet disinfection, and stand in the building without any peculiar smell.

In order to ensure power supply, they are equipped with high voltage from three substations and mobile diesel generators. Even if there is a power outage in Xiamen, the International Conference Center will operate normally.

In order to ensure the sound, according to the sound insulation requirements calculated by the acoustics experts, they have made a number of deepening treatments for sound insulation and sound absorption on the wall, and at the same time installed "silencers"-silencing sound boxes in the air-conditioning machine room and air-conditioning outlet, creating a real "pin drop sound" space.

After more than 180 days of day and night, the reconstruction project of Xiamen International Conference Center finally ended perfectly. Listening to the participants’ praise for the main venue building, Mao Dengwen, as the representative of the builder, was sweeter than drinking honey.

"What’s the next plan?" Without thinking, Mao Dengwen blurted out, "Go home and have a good sleep, and continue the new journey …"

Cctv newsRecently, at the press conference on the development of industrial communication industry in the first half of the year held by the State Council Office, Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, gave a detailed introduction to the characteristics of new energy vehicles’ power exchange mode when answering a reporter’s question, which was clear in organization and could be called a textbook answer.

He believes that charging and changing electricity are both ways to supplement the energy of electric vehicles, each with its own advantages, its own application fields and consumer groups. At present, although new energy vehicles have made great progress, they are still in the early stage of industrial development. The technical route and business model are still being explored and changed. He suggested that everyone should support the innovative development of new technologies, new formats and new models, encourage enterprises to develop new charging and power exchange technologies, and explore the application of the mode of separation of vehicles and electricity to meet the needs of different markets.

Compared with the charging methods that you know more about, the power exchange mode also has its own characteristics. Xin Guobin can be summarized as follows.

First, the separation of vehicles and electricity can greatly reduce the cost of consumers buying cars.Now it is generally felt that new energy vehicles are relatively expensive, although the state has a subsidy policy. Moreover, the subsidy policy of this country has made it clear that the slope retreat will be completed by the end of this year. Due to the impact of the epidemic, it is decided to postpone the progress of slope retreat, and it can be extended for another period. Therefore, the separation of vehicle and electricity can greatly reduce the cost of car purchase for consumers.

Second, it can increase the convenience for consumers to travel.The time for changing batteries is even shorter than that for adding a tank of oil. Relevant comparisons show that, for example, if the power station is changed now, it takes less than 3 minutes for the car to drive in and out, and it takes 5 minutes or 8 minutes to add a tank of oil. Therefore, changing electricity is actually very convenient as long as you get used to it.

Third, the centralized monitoring, maintenance and management of batteries by battery operating companies is conducive to prolonging the life of power batteries and improving the safety of batteries.Consumers buy new energy vehicles, and many people just drive them, so the care, attention and maintenance of the vehicles are not so timely. In fact, the battery is also a very fragile component. In addition to the battery monomer, there is also the management problem of the battery pack, which requires high technical requirements and needs to be maintained and tested in time during use. Otherwise, there is a great risk during charging and one hour after charging. Once the thermal control and management are not good, deflagration may occur. Even with this problem, the spontaneous combustion rate of new energy vehicles is lower than that of traditional vehicles. Centralized management by battery operating companies can improve the safety of batteries. In fact, it is very important to change the concept. It is natural and normal for traditional cars to go to gas stations to refuel, so it should be possible for new energy vehicles and electric vehicles to change batteries and rent electricity.

The fourth is to use the difference between peak and valley electricity prices to reduce the charging cost.At present, new energy vehicles are often driven home to charge at night and charged at peak hours, so the price of electricity will be relatively high. If a battery operation company manages batteries, it can fully use the peak-valley preferential electricity price to charge, which can reduce the cost of renting batteries.

Fifth, we can consider how much electricity to rent that day according to the daily mileage.At present, the basic driving range of new energy electric vehicles is 400 kilometers, and a set of batteries in a car is six or seven hundred kilograms, which accounts for a high proportion of vehicle weight. In fact, most people don’t travel more than 50 kilometers a day. Imagine that if you want to run 50 kilometers today, you can rent 50 kilometers of batteries instead of carrying 400 kilometers of batteries, so the weight of the car will be greatly reduced and the power consumption will be greatly reduced. For the whole society, if everyone does this, it will be a great savings. If you are worried about how to rent 50 kilometers of electricity, as a battery operating company, you can do it if you want 50 kilometers and allocate 70 kilometers of electricity just in case there is a little problem.

There’s another way,It can solve the problem of difficult construction of charging piles in old communities.Now, there is still a concern for people to buy new energy vehicles. They live in an old community and need to build a charging pile. The voltage load in this community is not enough, so they can’t install it. When the charging pile company wants to install in this community, it encounters some problems, such as insufficient power load. Who will expand the capacity? Who will pay for the expansion? Therefore, it brings a series of problems. The construction of charging piles in old communities is a social problem and difficult to handle. Therefore, if the power exchange mode is adopted, this problem can be effectively solved.

Sixth, the power exchange model can also give birth to some new service formats.Nowadays, express delivery is very convenient. You can get to your side in 10 minutes by making a phone call. If the industry adopts the mode of changing electricity, engages in a tram and swims in the street, whoever proposes to change electricity must ensure that it will arrive within 10 minutes. In fact, there is no technical problem. This may give birth to some new service models.

Of course, there are still many problems to be solved to promote this power exchange mode. For example, the overall design of the vehicle, the battery box should be standardized and unified, there should be national standards, and the battery should also be standardized, whether it is soft or hard, square or cylindrical, the specifications should be standardized. In addition, the plug-in of batteries should also be standardized, which still needs further exploration.

However, from a technical point of view, there should be no major problems. Therefore, in the next step, the Ministry of Industry and Information Technology will continue to vigorously promote the construction of this charging and replacing infrastructure with relevant departments, further improve relevant technical standards and management policies, and encourage enterprises to develop battery replacement models according to usage scenarios. It will also support pilot projects in places like Beijing and Hainan to promote the high-quality development of new energy vehicles.

In this regard, some places are still moving faster, such as Beijing, where enterprises are ready to push this mode of power exchange. In some fields, such as buses in public transportation, some electric buses adopt the mode of changing electricity. In the field of taxis, some have adopted the electricity-changing mode. For example, after the taxis in Beijing adopted the electricity-changing mode, the order-taking rate increased by more than 30%, the driving mileage increased by nearly 30%, and the personal income of taxi drivers also increased by more than 30%.This is a very beneficial model for all parties.

In the next step, relevant departments will actively promote it. Xin Guobin also put forward an initiative. Welcome everyone to publicize these new things and new formats, give them more encouragement and support, let them mature at an early date, and make more contributions to the green development of the whole society.

　　The State Council Joint Prevention and Control Mechanism held a press conference on the afternoon of January 8th to introduce the tenth edition of the prevention and control plan, and pay attention together!

—— The tenth edition of the prevention and control plan—

　　What adjustments have been made to the tenth edition of the prevention and control plan?

　　One isUpdated the name of the disease. Renaming "novel coronavirus" as "novel coronavirus Infection";

　　The second isStrengthen monitoring and early warning. Under normal conditions, virus variation monitoring, case report, sentinel hospital monitoring, unexplained pneumonia monitoring and urban sewage monitoring are mainly carried out. In case of emergency, increase nucleic acid and antigen detection and monitoring, fever clinic monitoring, monitoring of key institutions, etc.

　　The third isAdjust the detection strategy.No longer carry out full-time nucleic acid screening, and community residents are "willing to check as much as possible" according to their needs.. For the staff and caregivers of key institutions such as pension institutions and social welfare institutions, antigen or nucleic acid testing should be carried out regularly during the epidemic period. Carry out antigen or nucleic acid detection after the symptoms of severe high-risk personnel in the community appear;

　　The fourth isAdjust the management of infectious sources. Infected in novel coronavirusNo longer implement isolation measures., the implementation of classification and treatment;Close contacts are no longer judged, and high and low risk areas are no longer delineated.;

　　The fifth isEmergency prevention and control measures can be taken during the epidemic..

　　These emergency prevention and control measures can be taken during the outbreak.

　　During the outbreak of the epidemic, comprehensive assessment should be made in combination with the variation of the virus, the epidemic intensity, the load of medical resources and the social operation, and temporary prevention and control measures can be taken timely and legally according to the infection rate of the population and the shortage of medical resources.When the epidemic situation breaks out and spreads in COVID-19, some emergency prevention and control measures can be taken timely, legally and selectively.

　　The tenth edition of the prevention and control plan lists some, including suspending non-essential large-scale activities and suspending the business activities of large-scale entertainment venues; Take appropriate current limiting measures in indoor public places such as museums and art galleries; Strictly manage places where vulnerable people are concentrated, such as pension institutions and social welfare institutions; Carry out the measures such as commuting at the wrong time and peak, flexible working system, or taking home office; There are also educational institutions that adopt temporary online teaching.Once the epidemic situation is alleviated, the local government should promptly announce the lifting of emergency prevention and control measures.

-virus mutation monitoring-

　　How to monitor the variation of Covid-19 in the first time?

　　Since the epidemic prevention and control entered a new stage, the disease control department has further improved the work plan of mutation monitoring in Covid-19. On the basis of the original work,The sampling, inspection and sequencing of entry personnel, patients, key places and key populations have been strengthened.. In terms of monitoring imported cases,Strengthen close cooperation with customs.. In terms of local case monitoring,Each province chooses some cities and hospitals as monitoring posts.To carry out sampling and sequencing of a certain number of Covid-19 infected cases in outpatient cases, severe cases and death cases, to dynamically monitor the trend of Covid-19 mutation, to capture new mutant strains in time, and to evaluate the changes of their biological characteristics, so as to provide a scientific basis for epidemic situation judgment, research and development and evaluation of detection reagents, vaccines and drugs.

　　What are the characteristics of XBB so far? Is the pathogenicity and toxicity stronger?

　　Our country has been carrying out monitoring work in Covid-19 since the new crown epidemic. From a global perspective, XBB series mutants are mainly popular in the United States, India, Malaysia and Singapore.Recently, XBB has also produced a new offshoot XBB.1.5 in the epidemic process. This evolutionary branch accounts for a large proportion of patients infected with Covid-19 in the United States at present, and it shows a growing trend.The US Centers for Disease Control and Prevention also monitored it, and predicted that XBB.1.5 may replace the popular advantages of BQ.1 and BQ.1.1 in the United States and become the dominant epidemic strain in the United States in the next few weeks. As of January 7, 2023, XBB.1.5 has been detected in 35 countries and regions around the world. Our national monitoring data shows that,From August 1, 2022 to the present, 16 cases of XBB local associated cases have been detected in our country, all of which are evolutionary branches of XBB.1.

　　From the results of many studies, compared with the original strain and the previously concerned mutant, such as Delta mutant and several early discovered evolutionary branches in Omicron, the evolutionary branches of XBB have obviously increased their immune escape ability, which has also led to an obvious increase in the spread advantages of XBB in these countries in the United States. From the current reports and studies, no increase in severe cases and deaths of XBB series mutants has been observed, that is to say, its pathogenicity has not increased significantly.

　　Why adopt the method of monitoring urban sewage?

　　Monitoring the sewage of residential buildings in Covid-19 can better play the role of monitoring and early warning for the residential buildings where they are located. Through community sewage monitoring, Hong Kong can find out the areas where there may be infected people in time, and then further track and find the positive infected people, and then take corresponding control measures, mainly when there is no large-scale epidemic in the early stage of the epidemic. The monitoring of Covid-19 in sewage treatment plants can evaluate the trend of Covid-19 infection in a larger area, which is suitable for monitoring for a longer time and a wider range. Monitoring points are set up in communities and sewage treatment plants, and their monitoring purposes are different.At present, Covid-19 infection in mainland China is still in the epidemic stage, so we carry out sewage monitoring in qualified cities across the country to assist in evaluating the epidemic intensity and changing trend of Covid-19 infection.To provide scientific basis for epidemic research and prevention and control.

-vaccination-

　　What are the key work requirements for vaccination in the tenth edition of the prevention and control plan?

　　First, further emphasize the principles of knowledge, consent and voluntariness.For school-age people over 3 years old, vaccination is encouraged if there is no contraindication.. In addition, advocate that the public, especially the elderly, should be vaccinated all the time, and those who meet the conditions should complete the enhanced immunization.

　　Second,One dose of booster immunization should be completed for eligible people aged 18 and above.. In the process of strengthening immunization, it is also emphasized that whether sequential immunization or homologous immunization is selected,Cannot do it at the same time, only one item can be selected..

　　Third, it further emphasizes the rightPeople with high risk of infection, people over 60 years old, people with serious basic diseases, and people with immunodeficiency.These people who are easy to cause severe illness after infection put forward the suggestion of strengthening immunity in the second dose. The interval between the second dose of immunization and the first dose of booster immunization should be more than 6 months.It is hoped that the protection level of these high-risk groups, the elderly and people with basic diseases will be improved by the second dose of immunization.The key is to improve the whole vaccination rate and strengthen the immunization rate.

　　How long can I get Covid-19 vaccine after infection?

　　If Covid-19 infection is confirmed by nucleic acid detection and antigen detection,Covid-19 vaccination is not recommended in the near future.. A number of studies have shown that the immunity generated by Covid-19 infection alone,Weaker than the immunity caused by virus infection and vaccination.. Therefore, some people need to be vaccinated according to the immunization program. According to the current regulations,The interval between infection time and inoculation time is not less than 6 months.. Mainly according to the previous monitoring and research,The proportion of infection within 6 months is still very low.. The interval between infection and vaccination is actually a part of vaccination immunization program. With the deepening of vaccine research and the need of disease prevention and control, the immunization strategy will be improved and adjusted accordingly, including vaccination interval.

　　Besides Covid-19 vaccine, which vaccines should the elderly be vaccinated to prevent respiratory infectious diseases as much as possible?

　　For the elderly, in addition to being infected with Covid-19, there are some diseases that can be prevented by vaccines, includingRelated diseases caused by influenza virus and pneumococcus, etc.,For the elderly, it can also lead to severe cases.. On the one hand, the old people’s immunity is weakening, on the other hand, most of them have chronic basic diseases. If they are infected with influenza and pneumococcus, the infected diseases will be severe among these people. In addition, some studies have shown that after infection, it will lead to the original basic diseases, such as asthma, chronic obstructive pulmonary disease, heart disease, diabetes and so on. So, in this case,It is suggested that the elderly people who meet the vaccination conditions should be vaccinated with influenza vaccine and pneumococcal vaccine in addition to Covid-19 vaccine.And make them better protected.

　　Generally speaking, children’s delayed vaccination with conventional vaccines will not affect the effect, but they should be replanted in time.

　　Vaccines should play a better role, first, in time, and second, in the whole process.If vaccination is delayed, generally speaking, the effect will not be affected.However, it will increase the risk of infection, because there is no whole process or vaccination, and immunity has not been fully established. Once there is a source of infection, it may be infected with diseases, and there will be such a risk. soIt is suggested that all localities should replant vaccines in time after the vaccination units return to normal work.Which vaccines have not been vaccinated and which vaccines need to be replanted, each parent has a vaccination certificate, which is recorded. According to the regulations, which ones did and which ones didn’t,After taking the vaccination certificate to the vaccination unit, the vaccination doctor will make corresponding arrangements according to the child’s situation.. During this period, some children are infected with Covid-19. As long as he has recovered and there is no contraindication for vaccination, the follow-up routine vaccine can be vaccinated or replanted.

—— Returning home during the Spring Festival—

　　During the period of Spring Festival travel rush, the mobility of people increased. What should the public pay attention to when taking planes, trains and other means of transportation?

　　People with fever, dry cough, fatigue, sore throat and other symptoms should avoid taking public transport and going to crowded places before excluding the risk of infection. People who feel that they have a high risk of infection,You should not travel until the risks are eliminated..

　　In places with closed environment and crowded people, such as waiting for the bus, taking planes, trains, subways, buses and other public transport, it is necessary toWear masks regularly throughout the process..

　　Keep a reasonable social distance in public places,Reduce close contact with others.

　　Do a good job in personal hygiene, especially pay attention to hand hygiene at any time and avoid contact with public goods. When coughing or sneezing, cover it with paper towels or elbows and throw the used paper towels into the trash can in time. If you come into contact with respiratory secretions, you shouldWash your hands or disinfect your hands in time. When you are out or take public transport, try to reduce the number of meals and try to eat at the wrong peak..

　　During the Spring Festival holiday, can the public get together for dinner as before the epidemic? What should we pay attention to in gathering activities?

　　First, advocate people to avoid visiting relatives and traveling in areas with high epidemic situation, and advocate people in areas with high epidemic situation to reduce travel.Old people and people with serious basic diseases should try to avoid traveling..

　　The second isTry not to hold large-scale family gathering activities., reduce the scale and number of friends and relatives gathering, shorten the gathering time and strengthen self-protection.

　　Third, according to the epidemic situation,Try not to hold large-scale temple fairs, large-scale indoor cultural performances, exhibitions and other activities., reduce the scale and frequency of rural fairs, and implement prevention and control measures such as ventilation and disinfection.

　　During the Chinese New Year, avoid passing on the risk of infection to the elderly at home.

　　During the epidemic period, healthy New Year is a public concern, and we should pay more attention to the following aspects:

　　The first isContinue to do personal protection.Adhere to frequent hand washing, wearing a mask, regular ventilation, public chopsticks system, keeping social distance, cough etiquette, cleaning and disinfection and other hygiene habits, even after recovery from infection, personal protection should be done.

　　The second isMaintain regular work and rest, reasonable diet, moderate exercise, good attitude and other healthy living methods., improve self-resistance.

　　The third isTry not to hold or participate in large-scale family gathering activities, and reduce the number of family and friends gathering.Shorten the dinner time, and you can also send blessings through video and telephone, especially to avoid passing the risk of infection to the elderly at home.

　　The fourth isPeople who meet the vaccination conditions,Complete the whole vaccination and strengthen immunization as soon as possible.Protect the health of yourself and your family.

　　The fifth isIt is necessary to strengthen health monitoringPay close attention to the health status of yourself and your family. If you have symptoms such as fever, dry cough, fatigue, sore throat, or when you test positive, you should stay in a well-ventilated and relatively independent room as much as possible, minimize contact with people living with you, pay close attention to the progress of your illness, and seek medical attention in time if your illness is serious.

　　CCTV News:Twenty-three years ago (1996), Lao Rongzhi was a Chinese teacher in a primary school in Jiujiang City, Jiangxi Province. On November 28 this year, she appeared in a case report issued by the police as a fugitive who had been on the run for 20 years involving three places and seven lives. It is difficult for people to associate a beautiful woman with a suspect in a serial murder case. In those days, after Lao Rongzhi absconded, this case and the Baiyin case in Gansu, as well as two other cases, were called the four unsolved cases in China by some media. So, how many secrets did Lao Rongzhi hide 20 years ago? After absconding for 20 years, how did she get caught?

　　Big data accurately judges and locks suspected fugitive women.

　　On the afternoon of November 27, 2019, using big data, the police found that a woman who was active near Caitang Square in Siming District of Xiamen was highly similar to the information of Jiangxi fugitive Lao Mouzhi in the fugitive library of the Ministry of Public Security.

　　Lin Guoqiang, the squadron leader of the Synthetic Operations Center of the Criminal Investigation Brigade of Siming Branch of Xiamen Public Security Bureau: We are verifying the household registration information, including her parents’ situation and family situation, including the possible direction of her escape after this incident. Moreover, she has basically no traces of social activities for so many years, so this branch of Lao has lost the direction of its activity track. There is no trace of Lao’ s branch. What is the identity of this suspected woman?

　　Suspicious women frequently appear and pursue their identity in depth.

　　The police of the task force immediately went to Caitang Square to investigate. During the investigation, the police found that Caitang Square is a business circle, but there are also many residential areas around it. Then, the suspected woman frequently appears here. Is she living here? Or do you work here?

　　After many investigations, the police finally got an important clue from a nearby business account.

　　Lin Guoqiang, Squadron Leader of Synthetic Operations Center of Criminal Investigation Brigade of Siming Branch of Xiamen Public Security Bureau:The suspected woman should be a friend of hers who had a watch counter in Dongbai Square in Caitang, and then her friend went on a business trip in the middle of November, and then gave her the watch counter in Dongbai Square in Caitang to help take care of it for a few days, so this woman appeared in Caitang Square.

　　Peripheral investigation, mastering its activity track, ambush

　　In addition, after an external investigation, the police learned that the woman would come to the store on the morning of November 28. The task force decided to arrest him immediately.

　　Lin Guoqiang, Squadron Leader of Synthetic Operations Center of Criminal Investigation Brigade of Siming Branch of Xiamen Public Security Bureau:When we approached the suspect, we still adopted some ways and means, observed it, and then asked her directly after it was over. This woman was relatively calm and calm at first.

　　When the police asked about her personal information, the woman kept prevaricating and refused to give a positive answer.

　　Reporter:What did she say?

　　Lin Guoqiang, Squadron Leader of Synthetic Operations Center of Criminal Investigation Brigade of Siming Branch of Xiamen Public Security Bureau:She invented a false name, Hong Yejiao, from Nanjing. We inquired about the population of Nanjing according to her age and the name she said, and found no such similarity.

　　Fabricate a false identity and still conceal true information in the face of trial

　　Subsequently, the police took the woman back to the police station for further investigation. During the trial, in the face of police interrogation, the woman refused to confess her true information.

　　Lin Guoqiang, Squadron Leader of Synthetic Operations Center of Criminal Investigation Brigade of Siming Branch of Xiamen Public Security Bureau:Is refused to explain, what also don’t say, don’t cooperate, ask what she didn’t answer, just shut up for you, so in view of this situation, we immediately collected her blood samples for technical inspection.

　　Extract biological samples for DNA identification at the first time.

　　This time, it is the DNA of a relative of the fugitive Lao that is compared with the biological sample of the suspected woman. In other words, if the DNA comparison is successful, the suspect that this woman is a fugitive Lao will be settled.

　　Lin Guoqiang, Squadron Leader of Synthetic Operations Center of Criminal Investigation Brigade of Siming Branch of Xiamen Public Security Bureau:After several hours of waiting, it was finally revealed that the suspected woman was a murder fugitive, Lao Mouzhi.

　　Wandering around many cities, doing odd jobs in bars and other places

　　After preliminary investigation, in 1996, Lao Mouzhi and the criminal Faziying killed a family of three in Nanchang, Jiangxi, and committed crimes in many places. In July 1999, Faziying was arrested in Hefei, Anhui Province, and a branch of Lao absconded. According to the confession of the criminal suspect Lao Mouzhi, in the past 20 years, in order to escape the blow, she not only changed her face, but also remained anonymous and used multiple false names, wandering between different cities, relying on odd jobs and short-term jobs in bars, KTV and other places for a living. Until November 28, 2019, it was captured by the Xiamen police in Fujian. At present, the police have not found that the criminal suspect Lao Mouzhi committed a crime during his flight to Xiamen, and the case is still under investigation.

Data picture mapping/Yang Hong

　　Total fundraising decreased by nearly 80% year-on-year.

　　According to the statistics of our data center, including Shanghai Electric’s non-financing IPO, 77 companies have appeared in Shanghai and Shenzhen stock markets through IPO since 2008 (6 main board companies in Shanghai stock market and 71 small and medium board companies in Shenzhen stock market). Except for Shanghai Electric, 76 companies raised a total of about 103.4 billion yuan, with an average price-earnings ratio of 27 times.

　　Since the beginning of this year, due to the deep adjustment of the stock market, the number of IPO companies and the total amount of funds raised have been greatly reduced compared with last year. The industry believes that the IPO is less likely to open in the remaining ten trading days of the year. Optimists predict that if the market is optimistic, it is expected to restart the IPO； in January or the first quarter of next year; However, pessimists said that the current market expansion pressure is still great, and it will take time to open the gate.

　　77 new faces appeared

　　Since January 1, 2008, the Shanghai Composite Index has dropped from a high of 5,522 points to 1,954 points on December 12, with a drop rate of more than 60%. The deep adjustment of the market not only makes investors "suffer huge losses", but also greatly reduces the scale of IPO.

　　According to the statistics of our data center, in 2007, a total of 123 companies were listed on the A-share IPO, including 23 main board companies and 100 small and medium-sized board companies in Shanghai. The total amount of funds raised was about 477 billion yuan, with an average price-earnings ratio of 30 times.

　　Compared with 2007, the number of companies listed through IPO in 2008 decreased by 38%, the total amount of funds raised decreased by 78%, and the average P/E ratio decreased by 10%.

　　In addition to the sharp slowdown in the pace of issuance, there have been few large-cap IPOs this year, with only five companies issuing more than 500 million shares, accounting for 6% of the total number of IPOs, compared with 17% last year. However, although the number is small, large-cap stocks still play a major financing role. The five companies raised a total of 73.3 billion yuan, accounting for 70% of the total IPO funds raised this year.

　　Among the 76 IPO companies this year, China Coal Energy raised the highest amount of funds, reaching 25.6 billion yuan; China South Locomotive issued the largest number of shares, with 3 billion shares; The number of shares issued by Chuanda Zhisheng, which was listed on June 23rd, is the smallest, only 13 million shares. Teerjia, which went public on February 1st, raised the least amount of funds, amounting to 122.2 million yuan.

　　At the same time, due to the continuous decline of the market, the increase of IPO on the first day of listing is also very different. Huarui Cast Steel, which was listed on January 16th, issued 54 million shares, raising 580 million yuan, with an opening increase of 206% and a closing increase of 189%. Huachang Chemical, which was listed on September 25th, issued 51 million shares and raised 510 million yuan, with an opening increase of only 75% and a closing increase of 85%.

　　From the industry point of view, in 2007, 10 financial and insurance companies went public through IPO, while in 2008, the number was 0; Among the IPO companies this year, the two industries with the largest proportion are machinery, equipment, instrumentation and petrochemical plastics, with 16 and 14 companies respectively.

　　Judging from the month of IPO issuance, there were at least four in March this year; At the peak in May, 18 companies were issued and listed. Up to now, no company has listed on the IPO in the fourth quarter.

　　It is worth noting that although Shanghai Electric, which landed on the Shanghai Stock Exchange on December 5, was also in the form of IPO, it adopted the method of exchanging shares to absorb the shares of Shanghai Power, and did not raise funds from the market.

　　The IPO has not been reviewed in the past three months.

　　Since Huachang Chemical landed in Shenzhen Small and Medium-sized Board on September 25th, the domestic A-share IPO has been at a standstill. Not only that, the IPO audit has also entered a "frozen period". Since the initial application of Hunan Boyun New Materials Co., Ltd. was approved by the Audit Committee of China Securities Regulatory Commission at its 135th meeting in 2008 on September 16, 2008, the Audit Committee has not conducted IPO audit for nearly three months by December 12, 2008.

　　According to the data of Wind, there are 33 companies that have "passed the meeting" but are still waiting in line for listing, including China Construction, Everbright Securities and China Merchants Securities. Among them, the first application for China Building was approved on June 5th, and it has been more than six months since then.

　　However, it is not just domestic A-shares that are stagnant in IPO. In the context of the global financial crisis and the sharp turmoil in the stock market, the global IPO process has slowed down significantly, especially in the United States. According to reports, since the last IPO on August 8, the US IPO market has been completely frozen, and there has been no harvest for several months, setting a record for the longest "vacuum period" of US IPOs since Thomson Reuters tracked statistics in 1980. Some people joked that American IPO entered the hibernation period ahead of schedule, and many bankers and investors have basically begun to pay attention to IPO activities next year, but no longer care about the rest of 2008.

　　When will the gate open?

　　Although there are still 13 trading days left in December, the industry believes that the possibility of restarting IPO this year is very small.

　　According to Wind data, the number of shares released in December reached 25.256 billion, second only to 27.55 billion in August, which was the second largest peak of lifting the ban in the year, and the financial pressure was still great.

　　Liu Jiazhang, a strategist at National Securities, said that the current market financing function depends entirely on the quality of the market. If there is a cross-year market, there may be some small and medium-sized board IPOs tentatively in January or the first quarter of next year.

　　Unlike Liu Jiazhang’s optimistic expectations, most people in the industry are relatively pessimistic. Xu Haiyang, chief strategist of Nisshin Securities, said that the current market environment does not have the conditions to restart the IPO, and there is no hope that the IPO will open for at least three months. The economy is located in the deceleration cycle, and the secondary market is expected to expand greatly, which greatly affects the market financing function.

　　Xu Wei, a strategic researcher at Guojin Securities, also said that it may be at the end of the first quarter and the beginning of the second quarter at the earliest, the Central Economic Work Conference proposed to maintain the stable and healthy development of the capital market, and the management will also consider the market situation more.

　　At present, the important problem to be solved in the stock market is not to promote more corporate financing, but to solve the "sequela" problem of share reform and expansion reasonably and smoothly. According to the statistics of brokers, the total number of "non-size" lifting the ban will reach 687.024 billion shares next year, which is the highest peak in the history of "non-size" lifting the ban, equivalent to 4.2 times the number of lifting the ban this year. After the lifting of the ban, the proportion of A-share tradable shares in the total share capital will soar from 37% at the end of 2008 to 74% next year.

　　Xu Haiyang pointed out that the focus of the macro-economy in the future is to maintain growth, and the focus of the capital market in one or two years is to solve the problem of expansion. Even if the newly listed stocks are not considered, the market value of tradable shares will expand by about three times in the next two years. Earlier, it was reported that the audit committee "dismissed" some companies that queued up for the meeting, which also reflected the management’s orientation. The capital needs of more companies may need to be realized through other channels than the stock market.

　　In addition, for the Growth Enterprise Market, Xu Wei analyzed that the Growth Enterprise Market will be launched when the market is stable, and it may take one or two hundred companies to launch at once when the Growth Enterprise Market is just launched, so that the market scale will rise and it is possible to trade and invest. However, the large-scale launch has great pressure on the market. Therefore, the management will first consider the opening of IPO in Shanghai and Shenzhen stock markets and slowly "release" the companies waiting in line for issuance. (Reporter Wang Jin)
