Analysis of plug-in hybrid car system in Willanda The interior is more luxurious.

If you don’t consider the cost of using the car later when you buy a car, you will regret it afterwards. For example, today’s performance in this respect is worth talking about. Let’s take a good look at it.

Let’s take a look at the appearance of the plug-in hybrid of Willanda. The design of the plug-in hybrid front of Willanda is very simple and sporty. The headlights are very simple and the visual effect is not bad. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light and so on. Coming to the side of the car body, the size of the car body is 4665 mm * 1855 mm * 1690 mm. The car adopts lovely lines, and the side of the car presents a stable design style. With large-sized thick-walled tires, it looks full of sports. In terms of the rear end, the lines of the plug-in hybrid rear end of Willanda are simple, the taillights are very simple and generous, and the overall layout is impressive.

Sitting in the car, the interior modeling took a solid route, which was consistent with the positioning of the car. The steering wheel design of this car is very tough, equipped with the functions of manual steering wheel up and down+front and rear adjustment, steering wheel heating and so on, and the palm fit is very high. Let’s take a look at the central control. With the 10.25-inch touch-sensitive LCD central control panel, the interior design is quite layered, and it looks scientific and technological. Let’s take a look at the dashboard and seats again. The car is equipped with a sports dashboard, which gives people a very tough feeling. The car uses a genuine leather/imitation leather mixed seat, equipped with functions such as electric adjustment of the auxiliary seat, electric adjustment of the seat, and tilting of the seat ratio. The overall comfort and wrapping are not bad.

The car is equipped with car networking, driving mode selection, remote control key, Bluetooth key, rear wiper, interior atmosphere light and other configurations, with rich functions, which greatly enhances its convenience of use.

This car has been introduced almost before, and I believe many users who buy a car have taken a fancy to its comfort and practicality. If you go offline and actually experience it, it is estimated that there will be many new gains.

A wild giant panda in Baoxing, Sichuan Province died after being rescued.

  When the giant panda was found, it could not move.

  On March 14th, the staff of the Forestry Bureau of Baoxing County, Sichuan Province confirmed to the media that a wild giant panda suspected of being ill in this county died after being rescued. On February 20th, the giant panda was found in the wild and sent back to the county for treatment.

  On March 15th, the reporter learned from the Propaganda Department of Baoxing County Committee that because there was no rescue center in the county forestry bureau, the giant panda was found and sent to chengdu research base of giant panda for treatment the next day. At present, they are also waiting for the test results to determine the specific cause of death.

  An industry insider who has been engaged in wildlife-related work for more than 20 years said that it was a bit surprising that the news said that the giant panda was only in his teens. The wild giant panda can live to be around 20 years old, and his teens are in their prime. At the turn of winter and spring, the death of wild animals is relatively concentrated, but the natural elimination is mainly the old, weak and sick wild animals.

  He was sent to Chengdu Panda Base for treatment.

  Currently waiting for the test results.

  According to previous media reports, on February 20th, a wild giant panda in Baoxing County, Ya ‘an stayed in a mixed forest for several hours and remained motionless. After observation, the giant panda has no trauma on its body surface, but it has been running nose and is in poor spirits. It is initially suspected that it is sick. After receiving the news, the staff of local forest public security and forestry departments rushed to the scene, put the giant panda into a cage and transported it back to Baoxing County, where the local forestry department treated the giant panda.

  On the 14th, the staff of Baoxing Forestry Bureau confirmed to the media that the wild giant panda died after being rescued. According to its introduction, the giant panda was found in the wild and sent back to the county for treatment. The giant panda is over 10 years old, and the specific cause of death is still unclear. "I haven’t got the test report yet," but judging from the effusion found in the giant panda’s chest at that time, it is preliminarily inferred that it was due to illness.

  On the 15th, the reporter learned from the Propaganda Department of Baoxing County Committee that the county forestry bureau did not have a treatment center because of the insufficient treatment conditions in the county. The giant panda was found and sent to Chengdu Panda Base for treatment the next day. They are also waiting for the test results. For some online speculations, the other party said that there is no basis for judgment without the test report. I hope everyone can wait patiently and the test results will prevail.

  In his teens, he is in his prime.

  Pleural effusion or caused by inflammation

  For the news that the wild giant panda died after being rescued, an industry insider who has been engaged in wildlife-related work for more than 20 years said that in terms of time, it is more difficult for wild animals to find food in winter, and at the same time, in order to keep out the cold, the energy demand is greater, which is a hurdle for many animals, so the turn of winter and spring is a time when wildlife deaths are concentrated. Many old, weak and sick wild animals will be eliminated naturally. During this period, when he was in the field, he also saw the bodies of many animals by the river, including pronghorn and rock sheep.

  "According to the current news report, the giant panda is most likely ill." According to the insiders, the giant panda is in his teens, in the prime of life, and has almost no natural enemies in the wild. In terms of large mammals, besides giant pandas, there are also some bears and snow leopards in Baoxing County, which pose a certain threat to adult giant pandas. However, it’s really hard to tell the winner when the two sides fight, so people rarely hear the news that adult giant pandas are attacked by other animals. At the same time, the giant panda was found to have no trauma, indicating that it had not experienced a fight.

  The insider said that as far as he knows, various parasitic diseases are one of the diseases that wild giant pandas are prone to, typically including roundworms in the body and scale mites on the body. Ascaris is familiar to everyone, but animals can’t take medicine like people. Regarding the discovery of hydrops in the chest mentioned in the news, he said that hydrops indicates inflammation, and the chest cavity is the heart, lungs and pleura, some of which may be diseased. Of course, the final exact cause of death still needs to wait for the test report.

  Injured pandas have been found before.

  Suspected of being attacked by other wild animals

  The reporter noted that due to the large number of wild giant pandas in China, it is not the first time that Baoxing County has found a giant panda that needs help because of illness and injury.

  According to media reports on May 6, 2016, villagers in Baoxing, Ya ‘an found a wild giant panda with obvious injuries on its ears, back, right hind legs and tail. The staff rescued him from the mountain. The injured giant panda was a male, 4 years old, weighing 44 kilograms. After that, he was sent to Ya ‘an Base of China Giant Panda Protection and Research Center for treatment. After consulting with surgical experts in Ya ‘an People’s Hospital and trying all possible rescue methods, the giant panda died at 14: 50 on the same day because of his injuries and ineffective rescue. According to experts’ analysis, this giant panda may have been injured because it was attacked by other wild animals.

The first trailer of "China Star Jump" Tian Liang demonstrates "Champion Jump"



 


  Zhejiang Satellite TV has created a large-scale public welfare star diving reality show "China Star Jump", and recently officially released its first trailer. As the star coach of star jump, diving prince Tian Liang appeared in the trailer, reappearing the style of "the return of the king", and said that he would take all the players to jump again in April.


 


  Although the program has not been officially launched, the "devil-like" training led by Tian Liang has started ahead of schedule with the approaching of the competition. Yesterday, Tian Liang met all the contestants for the first time, and trained 10 people in "Point Soldiers on the Battlefield". With such a huge training project, we had to "force" Tian Liang to make a surprise move, "broadcast gymnastics" to warm up, and collectively "play with glutinous rice balls" to test the water, which made the atmosphere at the scene increase sharply. In order to enhance morale, Tian Liang even moved the "champion jump" in the Olympic Games to the training site and demonstrated a difficult 10-meter flip jump for the athletes present, which attracted cheers. All the athletes were excited to say that they "finally saw the champion jump".


 


  Tian Liang 10-meter demonstration jump kills the audience.


 


  Chen cursor exclaimed, "I finally saw the champion jump."


 


  As the first meeting with the students, Tian Liang gave a heavy "meeting ceremony" on the spot-the 10-meter platform flip jump, and the scene switched to the Olympic mode in one second. Although he retired for many years, the chemical reaction between Tian Liang who stood on the 10-meter platform again and the platform was triggered immediately. From jumping to tumbling to entering the water, every movement was flawless and perfect, and immediately the spectators in the audience were killed. The players were stunned and excited. "Finally, I witnessed it with my own eyes." In the trailer of "China Star Jump" released recently, Tian Liang also said that "this is the place where my dream began" and "I will jump again with the contestants". This jump once again proves the strength of the diving prince, and at the same time, it greatly increases the morale of the scene. In the next one-on-one training, Chen cursor can be inspired to volunteer to take the lead in training. Although there are many difficulties in the midway due to physical problems, Biao Ge still encourages himself with his iconic "rustic laughter", and he even turns into a Tian Liang fan and POSE for a photo with the star captain.


 


  Tian Liang’s own unique training method


 


  Broadcast Gymnastics Warm-up "Tangyuan" Test Water


 


  In order to quickly achieve the goal of promoting rookie players to professional players, Tian Liang created a unique training method that day. With a group of players doing "broadcast gymnastics" by the pool to warm up, Tian Liang seems to be a parent. On weekdays, the players with the star aura temporarily crossed into the student days, and in addition to listening carefully, they also tried their best to compete for favor in front of the teachers. Chen cursor’s beer belly made his movements too slow, so he won many personal instructions from Tian Liang, which caused Wen Ya’s dissatisfaction that "the coach is biased". For the 64-year-old cow father, Tian Liang also took good care of him, especially during the exercise, and personally accompanied him in one-on-one practice. Considering that some players are timid and afraid of water, Tian Liang led the players to collectively "dive the glutinous rice balls" to test the water, which set up a psychological guarantee for the timid players. When a group of people shouted for the run-up to the pool, they forgot to be afraid or even forget the pain of being choked and slapped by the water. Although Tian Liang scored one to ten that day, all the trainings were carried out in an orderly way with the original training method and friendly smile, and the results were good. The contestants also said that they had gained a lot and looked forward to the second class in Tian Liang.

On the battlefield, will artificial intelligence defeat human intelligence?

  On March 15th, 2016, Google’s artificial intelligence "AlphaGo" defeated Go world champion Li Shishi with a disparity score of 4-1. On May 27th, 2017, China’s Ke Jie, who is recognized as the world’s No.1 Weiqi player, lost 0-3 in a three-piece chess contest with Afa Dog.

  It is reported that in the research team of "Afa Dog", only Huang Shijie can play Go for four amateur paragraphs. The level of amateur four-stage Go may only be to understand the basic rules and some simple skills of Go. And once he is combined with the artificial intelligence "Alpha Dog", he can actually play a super-class chess player without winning. This fact reminds us that a commander who understands basic operational rules and tactical principles, if combined with the corresponding operational command-aided decision-making artificial intelligence, will defeat the first-class military commander without artificial intelligence?

  Where does artificial intelligence come from?

  Electronic computers and the Internet are born in response to military needs, and so is artificial intelligence, a branch of computer science. In 1939, World War II broke out and Britain declared war on Germany. Alan mathison turing, a mathematician and logician engaged in research work in Cambridge, enlisted in the army and joined the code-breaking station ordered by Churchill. The deciphering machine named "Turing Bombe" developed by them successfully cracked the communication code of the German Supreme Command Center, code-named "Enigma". Later generations commented that the "Turing Bomb" advanced the end of World War II by at least two years. After the war, Turing mainly engaged in the pioneering research of computer programming theory, neural network and artificial intelligence. He was called "the father of artificial intelligence" because of a series of outstanding achievements.

  According to the Chinese definition, "intelligence" includes people’s "wisdom" and "ability", that is, intelligence and ability. The English expression of artificial intelligence is: artificial intelligence; Artificial means "artificial" and "imitation", which is strictly translated. Only Artificial Intelligence can be translated into "artificial intelligence" or "artificial intelligence". In fact, the current "Alpha Dog" is really just a "Go Brain", which decides how to play chess, and the chess movement is done manually.

  The superb Go level of "Alpha Dog" benefits from the deep learning method provided by new technology with big data science and technology as the core. It can be described visually as follows: the program only describes the learning and thinking methods of "Alpha Dog", and the improvement of its intelligence level depends on the accumulated data. For "Alpha Dog", the data include the chess score of Go masters, the chess score of real opponents and the chess score of "Alpha Dog" playing by itself. These chess scores are the source of "intelligence" for "Alpha Dog" to improve its chess skills. In terms of digesting the chess score and learning progress, the ability of "Alpha Dog" is beyond anyone’s reach. Ke Jie, the world champion, can play up to 1,000 chess games a year, while Alpha Dog can play 1 million chess games a day.

  This makes the improvement of "Alpha Dog" chess power open, and there is almost no "ceiling". On the premise of not modifying the "Alpha Dog" program, the "Alpha Dog" can achieve the progress and improvement of "new day by day" or even "new from time to time" as long as the chess score of high-quality chess is continuously increased. It is objectively proved that the research team of "Alpha Dog" has basically mastered the winning mechanism of Go and described it in programming language.

  This remarkable ability includes two aspects: one is to judge the advantages and disadvantages of the existing disk; Second, based on this judgment, the possible position of the next move is decided, and a decision is made after the value judgment of several possibilities. Whether it is to judge the value of a certain move or the quality of the whole disk, it is necessary to construct a certain mathematical model and accurate algorithm.

  The success of "Alpha Dog" shows that its R&D team’s efforts in this regard are very close to human cognition, and machine learning has stood on the threshold of human brain learning. Super-first-class chess players found that "Alpha Dog" can even discover the laws and knowledge that human beings have not discovered for thousands of years from big data, which means that human beings have opened up new channels for expanding their knowledge system.

  What is the use of artificial intelligence

  Because of the realistic ability and potential ability displayed by artificial intelligence, all countries in the world are trying to use artificial intelligence for national defense and army building. As far as reality is concerned, the application of artificial intelligence in military field is mainly reflected in three aspects.

  The first is an unmanned combat platform. The existing unmanned combat platforms, whether unmanned aerial vehicles, robots on land or unmanned submarines at sea, have low intelligence. Generally, it only replaces people for some specialized operation. On the battlefield in Iraq, the US military used more than 4,000 robots to detect mines, roadside bombs and operate in some dangerous areas. The US military has more than 8,000 aerial unmanned systems and more than 12,000 ground unmanned systems, which have become an indispensable part of the US military’s operations. The development of artificial intelligence technology can make unmanned platforms more "smart" and improve the combat effectiveness of weapons and equipment, but it is not possible for unmanned platforms to make independent decisions so far.

  The second is intelligent precision ammunition. The US military used advanced laser or TV guidance in missile technology, which began in the Vietnam War in the 1970s. Its "Gemstone Road" missile hit more than 60% on the battlefield in Vietnam. The JDAM "Joint Direct Attack Ammunition" equipped by the US military adopts a more advanced guidance mode: inertial guidance +GPS satellite guidance. The "Joint Direct Attack Ammunition" during the Gulf War can only add target data before taking off. In the Iraq war, its receiver can receive the target data from navigation satellites, and can change the target at any time to destroy it, and its "intelligence" is obviously improved.

  The third is command-assisted decision-making. Think of "Alpha Dog" as a command and decision system of black-and-white confrontation, and its excellent performance in cognitive decision-making of black-and-white confrontation, and its ideas and methods should be used for reference for operational command and decision-making.

  Situation awareness on the battlefield is very complex, and multi-source intelligence gathers to form massive data, which cannot be completed by relying on the commander’s manual analysis. Artificial intelligence has great advantages over human beings in searching, storing, calculating and mining massive data. Introducing a deep learning algorithm similar to "Alpha Dog" to intelligently analyze satellite images and radar data will greatly improve the efficiency of intelligence analysis.

  In addition, at present, the cognitive understanding of the comprehensive battlefield situation depends largely on the commander’s experience and intuition. Using the "value" algorithm similar to "Alpha Dog" to judge the situation of Go and the probability of winning or losing, and learning from the "strategy" algorithm similar to "Alpha Dog" to determine the position of the player, it can provide auxiliary support for the commander’s operational decision.

  However, the application of artificial intelligence in the military field is far from reaching the level of independent decision-making like "Alpha Dog" Go. In November 2001, Predator UAV launched an attack on Al Qaeda military commander Mohammed Latif in Afghanistan, which became the first anti-terrorism actual combat of UAV. But it is the drone operator who controls from the rear who presses the "fire" command. Even so, it will inevitably bring collateral damage to innocent civilians. In 2013, Pakistani officials announced that since 2008, the US military has launched more than 300 drone air strikes in Pakistan, killing more than 2,000 innocent civilians.

  What is the future of artificial intelligence?

  From the situation that the world’s first-class Go players, Li Shishi and Ke Jie, have little chance to win the game against "Afa Dog" and the result of complete defeat, it is not exaggerated to draw the conclusion that artificial intelligence has surpassed human beings in the field of Go. In the game of Go, the obvious advantages of artificial intelligence are as follows: without fatigue curve, intelligence will not decay with time; There are basically no mistakes, and no opportunities will be given to opponents where they can; Free from emotional interference, not angry and impulsive because of the provocation of opponents; Learned and memorized, learning and playing chess more than ten million times before the game, which is beyond the reach of human beings; Powerful computing power is beyond the reach of human beings.

  But the victory of "Alpha Dog" is, in the final analysis, a human victory. The research on the mystery of human thinking and brain science is still superficial, and the development of human brain is far from exhausted, but the mechanism and composition of computers and artificial intelligence, no matter how powerful, are well known, because they were originally designed, manufactured and developed by people.

  At least so far, any artificial intelligence has the ability given by human beings. It is not surprising that it surpasses human beings in some ways. Humans make up for their own shortcomings by making various tools, a process that began in the Stone Age. Today, the major means of transportation far exceed human’s walking ability, and various machine manufacturing systems far exceed human’s unarmed manufacturing ability. Digitalization, networking and intelligence are the basic tracks of the development of the information society. It is expected that artificial intelligence will show its great power in the mature stage of the information society.

  Then, will there be a first-class military commander completely defeated by an artificial intelligence command system with strong deep learning ability in the battlefield in the future? To fully answer this question requires a masterpiece, but there are many essential differences between chess game and battlefield confrontation. For the following reasons, the author thinks the answer is no.

  One is the one-way transparency of the battlefield and the two-way transparency of the chess game. In the game of Go, both sides of the game are equal and transparent, regardless of the chessboard structure or the disk situation. However, the modern battlefield spans the virtual and physical space of land, sea, air, sky, electricity and internet, and the weather, weather, rain and shine, flood and tide are unpredictable. Clausewitz’s "battlefield fog" covers the battlefield. Even if it is a close confrontation, the battlefield space can never be transparent in both directions. The party with strong perspective observation can realize that the battlefield is more transparent to itself. Two-way reciprocal transparency in battlefield space has never existed and will never exist.

  The second is the certainty of the value of chess and the uncertainty of the effect of combat action. In the game of Go, the value of one player’s move is almost certain on the disk. An opponent can weaken the value of his next move, but he also has the same chance to fight back.

  However, the effect of combat operations on the battlefield is uncertain. In October 2001, the United States Joint Forces Command published "Effect-based Operations", and the US military formally accepted the theory of "Effect-based Operations". In 2008, General james mathis, the current U.S. Secretary of Defense and then commander of the United States Joint Forces Command, issued the Guide to Effect-based Operations, which officially abolished the theory of Effect-based Operations. Matisse’s reason is: "All combat environments are full of countless changing factors, so it is logically impossible to accurately predict the outcome of an action."

  The third is the authenticity and deception of the situation. On the board of Go, the situation of the board seen by both players is clear and true. But as Lenin said: "There is no war in the world without strategy." Strategic and tactical deception is a common tactic in war.

  The fourth is the strict game between the two sides and the potential multi-party participation. On the chess board, the two sides of the game are strictly limited between the two sides. Although there is a team behind the "Alpha Dog", it cannot change the nature that they are one of the two sides. In the history of human wars, especially since World War II, many local wars are actually "proxy war", where two sides or three parties join in the battle. Behind them, the situation is complicated and the behind-the-scenes promoters are hidden. For example, in the battlefield in Afghanistan, al-Qaeda is the target of the US military; On the Syrian battlefield, however, they may get some support from the US military because they are anti-Syrian forces.

  The fifth is the symmetry and asymmetry of space, time and weapons and equipment. In the game of Go, the time and space of both sides are symmetrical, and the weapons and equipment are black and white chess pieces. Although they are black first, they must pay back. In the real battlefield, preemptive strike is asymmetric in time, and air-to-ground attack is asymmetric in space. The wars of the United States against Iraq and Afghanistan are the wars of information-based weapons and equipment against mechanized weapons and equipment in the agricultural era, respectively, and there is intergenerational asymmetry in weapons and equipment between the opposing sides.

  Sixth, the certainty of chess rules and the flexibility of operational principles. In the game of Go, "Jinjiao’s silver-edged grass belly" is the basic value judgment criterion, and it is the basic chess rule … … The connection is broken, the dragon is encircled, and the eye position is broken, which is to avoid passivity with all one’s strength. These rules are basically certain and must be observed. Militarily, victory is no longer an important tactical principle. However, in the Anti-Japanese War, Liu Bocheng made a second ambush in Qigen Village, which became a classic of military command and a stroke of genius.

  Clausewitz said: War is a kingdom of uncertainty. The most essential difference between Go and military confrontation is the difference between certainty and uncertainty. The success of artificial intelligence is an amazing scientific achievement; But military command is not only science, but also art. The superb command art is more derived from the commander’s imagination and inspiration, generate, who said, "The wonderful operation is single-minded".

  Generally speaking, the application of artificial intelligence in the military field will enter an unprecedented active era with the development of technology, but the leader of war or battlefield will always be people.

Zhang Xiaojing talks about financial support for science and technology innovation: giving risk pricing to the market, establishing fault-tolerant mechanism and inclusive supervision.

Zhang Xiaojing, Director of the Institute of Finance of China Academy of Social Sciences and Director of the National Finance and Development Laboratory, The Paper reporter Zhou Yushe

On September 22nd, at the 5th Bund Financial Summit in 2023, Zhang Xiaojing, director of the Institute of Finance of China Academy of Social Sciences and director of the National Finance and Development Laboratory, pointed out that risk and uncertainty are the "bridges" between finance and science and technology innovation. For scientific and technological innovation, the biggest problem is how to deal with the risks and uncertainties faced by innovation and how to cross the "valley of death". For the financial system, risk pricing and risk allocation are its most basic and important functions.

"It is risk and uncertainty that make finance and technological innovation have a natural connection, and also provide a perfect reason for finance to support technological innovation." Zhang Xiaojing said that a financial system has advantages in identifying risks, pricing risks and allocating risks, so it must also have advantages in supporting scientific and technological innovation.

Focusing on China’s financial support for scientific and technological innovation, Zhang Xiaojing pointed out the "soft underbelly":"The lack of risk identification ability, the dysfunction of risk pricing and risk allocation are precisely the Achilles heel of China’s financial system, which has also become the fundamental reason for the lack of financial support for technological innovation."

Zhang Xiaojing said that the "four-in-one" catch-up model (the "structural advantages" of state-owned enterprises, the development responsibility and soft budget constraints of local governments, the institutional preferences of financial institutions and the last resort of the central government) makes the risk pricing and rational allocation of financial resources not determined by the market, but largely influenced by government intervention, leading to distorted risk pricing and improper allocation of financial resources. Some departments get a lot of credit funds, but fail to bear the corresponding risks-this is caused by implicit guarantee, rigid redemption and too big to fail.

However, this does not mean that the government cannot play a role in it, but emphasizes that the role of the government should also be played on the premise of not damaging the decisive role of the market.

"Financial support for science and technology innovation needs an’ ideological enlightenment’." Zhang Xiaojing said that the value of capital depends on future expectations, not the past, which is a real revolution and "ideological enlightenment" in financial epistemology. It is this revolution that laid a theoretical foundation for financial support for scientific and technological innovation: because the current financial support for science and technology innovation depends on the "expectation" of future scientific and technological innovation achievements.

Zhang Xiaojing said that it is necessary to respect the laws of the market economy and promote the reform of financial marketization. Putting the focus of economic development on the real economy does not mean that finance can be dispensed with, or that finance is in a completely subordinate position. The development of China’s socialist market economy in the past 40 years is to liberate the role of finance as a cashier in the planned economy era and give full play to the dynamic role of finance in promoting the transformation of savings-investment and economic catch-up and development.

He said that the relative independence of finance is precisely the premise that finance can better serve the real economy, abandon the "traditional" thinking that finance is only a vassal and mirror image of the real economy, and accurately understand the dialectical relationship between economic and financial symbiosis and common prosperity. The development of finance does not necessarily lead to the hollowing out of the industry, and the strength of American science and technology is closely related to its developed financial system; High-level science and technology can’t stand on its own feet without the support of a modern financial system.

In Zhang Xiaojing’s view, promoting financial market-oriented reform, getting rid of implicit guarantee, illusion and ownership discrimination, and improving the decisive role of finance in risk pricing and risk allocation are the institutional guarantees for financial support for science and technology innovation.

Financial support for science and technology innovation must also understand the law of scientific and technological innovation, especially the basic law of transforming scientific and technological innovation into actual productivity. Experience shows that the influence of the adoption of new technology on productivity growth is underestimated at the beginning and not overestimated at the end, which is generally in a "J curve" mode.

Talking about innovation failure and fault-tolerant mechanism, Zhang Xiaojing said that from the micro level, investment failure should be allowed, and state-owned enterprises should establish fault-tolerant mechanisms. To tolerate fluctuations and bubbles at the macro level, keeping the bottom line of risk does not mean zero tolerance for financial risks. The function of finance is realized in fluctuation, just as the function of price mechanism is that price is realized around value fluctuation. This means that supervision should be inclusive.

In addition, Zhang Xiaojing also talked about preventing technological development from succumbing to financial laws. Technological development is completely determined by market or financial laws, which may deviate from the social optimal goals, such as investing heavily in the research and development of late-stage therapeutic drugs, rather than the research and development of early-stage preventive drugs; AI technology is more oriented to replacing labor than empowering or assisting labor.

"Risk identification, risk pricing and risk allocation are the’ soft underbelly’ of China’s financial system, and the lack of modern financial thinking leads to improper evaluation of science and technology innovation (enterprise) is the’ soft underbelly’ in concept understanding." Zhang Xiaojing concluded that the solutionWe need an ideological enlightenment, leave risk pricing and risk allocation to the market, respect the laws of market economy, grasp the laws of scientific and technological innovation, establish fault-tolerant mechanisms and inclusive supervision, strengthen international cooperation and improve global scientific and technological governance.

How to judge whether tea is good?

"Source of this article: People’s Daily Press"
A friend often asks me, "How to judge whether tea is good?" I seriously replied: "Tea looks clean, and it tastes sweet and delicious, which is good tea." They didn’t think so. They thought I was either perfunctory or empty. No way, I have to talk about how to judge whether tea is good.
Appearance. The shapes of tea are various, and the most common ones are strip-shaped, curly, long and round. No matter what the shape of tea leaves is, it is judged by the rope, tenderness, thickness, weight and uniformity of tea leaves. Usually, the rope is fine and tight, the gap is small, and the volume is small, followed by the bulky and loose one. Generally speaking, no matter what shape of tea leaves are, as long as they are compact and heavy, without yellow flakes and thick branches, they will not be bad.
Gloss. It is difficult to subjectively say which color of tea is absolutely good for tea from different producing areas and different technologies, but one thing can be objectively judged, that is, the gloss of tea. No matter what color tea is, as long as it looks bright, oily and textured, it is good tea.
Dry humidity. The water content standard of all kinds of tea is kept at 5%-7%. More than 8% of tea is easy to age, and more than 12% of tea is easy to mildew. At present, many tea farmers deliberately control the water content at more than 10% when making crude tea, so that the weight of tea will increase. This kind of raw tea will feel very good when it is first tried out of the oven, but the taste will change completely after a while, so the dryness and humidity of tea is very important. I introduce a method to measure the moisture content of tea by hand: hold a large handful of tea in your hand for three to four times repeatedly, and there is a tingling sensation in your hand. When you hear the sound of broken branches, the moisture content of tea will generally not exceed 8%; The tea with water content above 10% has no tingling sensation in the palm of your hand when you hold it, and the tea is a little soft and smells green. Of course, there is also a remedy to buy tea with high water content, that is, put the tea in an air-conditioned room with air conditioning, which can not only remove some water from the tea, but also prevent it from rapid oxidation.
Soup color. The color of soup refers to the color of tea soup after brewing, which can be divided into three types: normal color, bad color change and old color change. Normal color refers to the tea made under normal harvesting conditions, and the tea soup shows the normal color after brewing. For example, green tea or green tea is green or light yellow (also called goose yellow) after brewing; Black tea is red soup color or golden soup color, red and bright. Bad discoloration means that it is difficult for tea soup to present its proper color because of improper collection, transportation or initial preparation of fresh tea. For example, the soup color of deteriorated green tea is grayish brown or reddish in yellow. Aging discoloration means that it is difficult for tea soup to present its proper color due to aging in the production process. For example, if the tea leaves are not kneaded in time after fixation, and are not spread to cool or dry in time after kneading, the soup color of new tea will be old. Properly made new tea, the soup is bright and crystal clear; When the tea is aged, the soup color is yellow, brown and gray, and the turbidity is everywhere.
The above are some opinions on "observing the face and observing the color". Let’s talk about the soul of tea endoplasm.
Smell the fragrance. Different land, climate, varieties and production techniques make the aroma of all kinds of tea have their own characteristics and styles. As a whole, it can be summarized into five evaluation factors: purity, richness, freshness, flatness and coarseness.
Pure: the fragrance is pure, and there is no miscellaneous taste and greasy feeling.
Strong: The aroma is strong and long.
Fresh and refreshing: the smell is fresh, which makes people feel refreshed, such as being in a mountain or a place with a good ecological environment, and feeling in the air with high negative ions.
Ping: The aroma is plain, and there is no strange smell.
Coarse: fragrant, but the fragrance is mixed, choking the nose and spicy.
The durability of aroma is also a factor to judge the quality of tea. I condensed the criteria for judging good tea into four simple words-quiet and elegant, and the durability of tea is reflected in the word "quiet". "Quiet" means that the aroma of tea is long and lasting.
I sum up the smell of incense as follows: the pure is pure, the fragrance is elegant but not greasy, and the light and tasteful is quiet. With this feature, good tea is undoubtedly also.
Let’s talk about the taste of tea. Taste means the feeling after drinking. Alcohol is just right. Tea tastes fresh, mellow, fragrant and sweet. The taste of inferior tea is bitter, coarse and pungent, and some people interpret this performance as strong and sweet, especially the tea drinkers of the older generation in Chaoshan often describe this bad taste as "fleshy", "full mouth" and "strong enough".
Sometimes the tea soup tastes bad, which may be due to the thick water. Rough water is not a feeling, but a fact. Sometimes, we feel that after drinking tea soup, there are attachments on the tongue surface or the bottom of the tongue, which makes the tongue surface feel rough. This is because there are more particles in the tea soup. There are two sources of particulate matter: first, the tea processing process is unsanitary, dust and sand are attached, or wood ash particles are caused by improper baking with charcoal fire, which belongs to foreign coarse particles; Second, the release of particles is related to the quality of tea. For example, the tea growing at low altitude has high temperature, fast growth speed, thick leaves and loose fibers. After making and baking at high temperature, once soaked, the crumbs and particles on the edge of tea will dissolve in water, making the tea soup more particles and the tea soup thicker. This is an endogenous particle, which will have a dull and astringent taste after drinking.
In front of me, I talked about several basic elements of tea evaluation, from the shape, appearance and gloss of tea to the color, smell and taste of soup, and finally talked about the evaluation of leaf bottom.
Many people drink tea, whether they understand or not, they will pick up the cover bowl and smell it, and then poke the tea with the cover. The technical term of this link is "viewing the bottom of the leaf". Viewing the bottom of leaves is also a method to judge the grade of tea. Generally speaking, the color is the first thing to look at at the bottom of the leaves. After fully brewing, the leaves are spread out and the color is uniform, and one side is not red and the other side is green. The texture of the leaves is oily, there is no obvious explosion point or burning point, and the integrity of the leaves is high. It is good tea to have such a leaf bottom. Of course, tea culture is profound, and not all teas are the same. Some teas with obvious characteristics, such as Jin Junmei in Tongmuguan, are still tall and straight after soaking in water for more than 20 years, and each bud head is bright and thick, like a red tassel gun head; If it is Jin Junmei made of green tea buds from Guanwai or Jiangxi, after several times of brewing, all the buds will stick together and never stand up again.
Of course, these people need to be judged by people who have rich experience or major in tea research, and ordinary tea drinkers don’t need to spend so much energy to study these problems.
