Is Baidu search engine dead?

No money, no floor washing, let me briefly talk about my opinion.

The article "Search Causes Baidu to Be Dead" written by Teacher Fang Chengcheng has been screened in the workshop. I accidentally brushed this article when I was in a traffic jam, and then I finished reading it by waiting for the traffic lights. Originally, I didn’t want to say anything more, but this article was a bit powerful. A fellow villager sent a WeChat asking me what I thought, so I simply threw a brick to attract jade to say something about my opinion.

Teacher Fang’s article can be summarized as follows: Baidu uses search function to promote its own products, such as Baidu Encyclopedia, Baijiahao, Baidu Post Bar and iQiyi. Simply put, Baidu is using its search to promote its own products, the largest search platform in the Chinese world, and it has become an internal search tool for Baidu’s whole family.

There is nothing wrong with this logic. But the conclusion has become "the huge Chinese Internet has fallen to such a state that there is not even a search engine."

null

How can you say that? Isn’t there sogou and 360?

I think what Teacher Fang means is that Baidu is no longer the fun for users to explore Chinese websites and new things, but has become a closed, selfish and rotten platform.

Fang and I are from Anqing, Anhui Province. Arguably, there are so many people in Anqing. Why do I know about him? The main reason is that he attended the science experimental class in Anqing No.1 Middle School. There are only four experimental classes in the province, and the people inside are either Peking University Tsinghua or rattan school, which can be said to be the elite of the elite. I was particularly envious in those days, because I studied poorly, and Teacher Fang lived up to expectations. I was admitted to the highest institution of higher learning, but unexpectedly became a reporter after graduation.

Ok, digress, what I want to say is that everything is elite from the elite perspective of Mr. Fang. If you have a slight impression, you should remember that Mr. Fang wrote an article "We live in a dung-like information environment", which is also fake news, but the gun is aimed at the American media.

The elite has the elite’s access to content, and the people have the people’s access to content. However, the elite should not require a search product for the public to become an elite and niche product, which is not in line with commercial interests and implies that the media should guide the people’s direction.

I don’t think there is anything wrong with the content of Baijiahao. Baijiahao does have a low quality of content, and there are fake news and headline parties, but will it be solved if it is replaced by People’s Daily and Sina News?

A person who watches story meetings may love to watch story meetings all his life, while a person who watches Caixin may not watch story meetings all his life. Why should the tastes of two people be mixed together?

Another question is actually worth discussing, that is, was the stationmaster era before Baidu very good? Not really. At that time, the rise of personal webmasters, who would toss computers, all set up their own websites, such as TOM, which had a large amount of traffic, and also had a small personal website. At that time, even the filing was not needed. Simply put, it was a vast world with great potential.

So how did the webmaster produce content? I know a webmaster. He told me how he "numbered" in those days: he bought a batch of books in a bookstore, such as mechanical engineering, and then hired a group of people to carry the contents of the books to a computer to make websites with various themes, and then hung them up in advertising alliance. As long as someone came in, he just sat and waited for the money.

What’s more, hang a beautiful woman or seductive copy on the homepage of the website to lure you into it.

(Screenshot of Baidu app Wang Jianlin keyword, in fact, the content of Baijiahao is not much)

There’s nothing new under the sun. Now it’s almost the same from the media as when I made a website. Flow is king, simple and rude, simple things are repeated, and leeks are cut from back to small pots of tea, so someone pays the bill.

As for Baidu’s diversion to the whole family barrel, to be honest, I personally feel that there is nothing wrong with Baidu’s diversion to its product matrix, and it is just as naive as asking Wang Jianlin why he only spends money on Wang Sicong. But on this issue, I agree with Mr. Fang Cheng’s point of view. Commercial companies should really consider the user experience and should not put their strategic objectives above the user experience.

Baidu is forced by today’s headlines, and advertising revenue is Baidu’s lifeline. However, with the rise of headlines, the cakes grabbed are actually Baidu’s customers, and the sales of headlines are particularly strong, so Baidu is desperately pushing information flow, and the content foundation of information flow is Baijiahao.

The current logic is equivalent to Baidu PC leading traffic to Baijiahao, while Baijiahao grows, and the information flow will follow, while Baidu app, the core of Baidu Mobile, is the main battlefield of information flow, which is a bit like the left hand making the right hand. You know this.

In 19 years, the promotion budget of Baidu app is 400 million yuan. Please feel this strength.

As for using Baidu to search for information, everyone has his own way. I have always advocated scientific internet access, but it is not Google’s omnipotent theory. It should be said that everyone should have their own familiar access to information and ways. If a thing is stupid enough to only use Google or Baidu, then this person is a sign of low ability. I generally don’t recruit people who ask Baidu everything. Of course, everything is the same as asking Google.

Generally, my interview question is this: Will you use Google over the wall? Yes, ok. Please name more than five websites or apps that you often visit besides Google Facebook Twitter. I don’t know. Ok, ask my assistant to get the taxi fare, and you can get out.

I wrote in my own editing manual that I should be good at using Zhihu, Weibo, WeChat search, major news websites, Reddit, and even quora, soup is not hot, watercress, get, tubing and other channels.

More refined, you even need to be familiar with some preferences of KOL (called influencer abroad), so as to get information quickly.

Friedman loved popularizing economics in his early years, often appeared on TV and wrote columns for newspapers. In his later years, he said with regret that he had worked hard to popularize economics for so many years and found that people’s understanding of economics was still standing still.

Therefore, I think it is better to give freemen some space to see more things they like, and not to force them to see something that seems correct, valuable and meaningful under the slogan of political correctness. This kind of thing has been staged in the 20th century, so don’t do it again. Finally, to quote my favorite Russell’s famous saying, jagged polymorphism is the source of life.

Isn’t that nice?

An Easy-to-understand Marxist "Introduction Guide"

  editorial comment/noteIn October 2017, the 19th National Congress of the Communist Party of China, "Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era" entered people’s field of vision for the first time, and the cause of Socialism with Chinese characteristics opened up a new realm. Tracing back to the source, looking for Kinomoto, and learning to understand the new ideas of the supreme leader and the spirit of the 19th National Congress of the Communist Party of China is a key, but it is deeply hidden in the centuries-old Marxist theory, which is also the best way for us to commemorate Marx — — Really understand and recognize the contemporary value of Marxism.

  So, from what angles should we start to understand the contemporary value of Marxism? The latest issue of Qiushi articleHow to Understand the Contemporary Value of MarxismCleared up our thoughts for us. Chen Xianda, a professor at the National People’s Congress, explained, like an easy-to-understand Marxist "introductory guide", several biggest doubts hovering in our hearts were answered:

  1. How to correctly grasp the basic principles of Marxism?

  2. How to treat the basic principles and individual judgments of Marxism?

  3. How to accurately grasp the core essence and essence of Marxist theoretical system?

  4. How to accurately refute the "outdated theory" of Marxism?

  The most important thing is that it also clearly answers an ultimate question that we are most concerned about:How does the new thought adhere to, develop and innovate Marxism??

  The article points out that the most distinctive theoretical character and outstanding theoretical advantage of Marxism is to keep pace with the times. This characteristic runs through the practice of China’s revolution, construction and reform. This process is the process of combining the basic principles of Marxism with the reality of China and making Marxism China. Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, the basic principles of Marxism and other theoretical achievements of Marxism in China.Although they were formed in different historical periods and devoted to answering different topics of the times, they all stand on the same political standpoint, have the same theoretical basis, theoretical essence, theoretical quality and value ideal, and belong to the same scientific theoretical pedigree..

  The supreme leader’s socialist thought in the new era has just adhered to and developed the basic principles of Marxism.With great theoretical courage, he has made original contributions to the development of Marxist philosophy, political economy and scientific socialism theory, and scientifically answered the major issues of the times, such as what kind of Socialism with Chinese characteristics to uphold and develop and how to uphold and develop Socialism with Chinese characteristics.. Therefore, we can say that the new ideas of the Supreme Leader are Marxism in the 21st century and Marxism in contemporary China. We should have such theoretical consciousness, but also such theoretical self-confidence.

  Time is a panacea for testing truth. Nothing can better reflect the treasure and admiration of an ideological theory than the development in inheritance; There is no ideological theory, like Marxism, which has an invincible and powerful spiritual core while expanding its own extension with the development of the times.

  Lenin said that Marxism is "a whole piece of steel". This whole piece of steel is self-contained and inseparable, and it will surely become a permanent cornerstone of Socialism with Chinese characteristics’s cause.

Take root in China and cultivate modern talents with ideals, responsibility and international vision in the new era.

  The 2020 CCTV annual education festival "Cloud Ecology Talking about the Future" was held in Beijing this afternoon. Many guests came to the event site to explore the new ecology of education and take the pulse of the new trend of future education development. Wu Xiaoqiu, Chairman of Higher Education Professional Committee of China Education Development Strategy Society, Dean of China Capital Market Research Institute, First-class Professor of Finance and former Vice President of China Renmin University, attended the ceremony and delivered a keynote speech entitled "Rooting in China and Cultivating Modern Talents with Ideality, Responsibility and International Vision in the New Era".

  The full text of the speech is as follows:

  Education is the foundation of a strong country. Education is also the cornerstone of the rejuvenation of the Chinese nation. "Education makes the country strong and education makes the country prosperous" is not a slogan, but it is real.

  Looking back over the past 40 years of reform and opening up, we will find the importance of education and talents. In 1978, the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China was successfully convened, which started the process of modernization in China. The historic speeches of the Third Plenary Session of the Eleventh Central Committee of the Party and Comrade Deng Xiaoping’s "Emancipate the Mind, Seek Truth from Facts, Look Forward with Unity" have promoted the social changes in China. Over the past 40 years, China has gone from a poor and backward country to a well-off society as a whole.

  In 1978, China’s per capita GDP was just over $100, and it will obviously exceed $10,000 by 2020. From the per capita GDP of more than 100 US dollars to more than 10,000 US dollars today, this is a miracle of human society and a great contribution made by China to human society.

  The most important reason is that we persist in the reform and opening up and the socialist market economy. Among them, the great contribution of higher education in China to the realization of a well-off society in China cannot be ignored.

  Many people judge a country’s higher education by whether it wins the Nobel Prize or not. I don’t think this is comprehensive, accurate and correct. China’s higher education has trained tens of millions of talents, including scientists, engineers, entrepreneurs, civil servants and builders of every industry in the past 40 years, which has made great contributions.

  The talents trained over the past 40 years have several characteristics: the first is that they have an international perspective. Focusing on the future, it knows where China will go in the future and can grasp the future trend. The second is the spirit of responsibility. The spirit of responsibility was particularly evident in the last three sessions in the late 1970s and those in the early 1980s. In 1980s, China society was an era of great ideological emancipation, which gave birth to a group of elites in today’s society. They knew their responsibilities. The most important thing in ideological emancipation was to grasp their responsibilities, put their own interests at a very low level, and put social responsibilities at a very high level. Therefore, there was a heartfelt slogan at that time, called rejuvenating China. This is not organized, it is heartfelt and spontaneous. Today, this generation has become the mainstay of this society.

  Our future, from 2020 to 2035, the Fifth Plenary Session of the 19th CPC Central Committee described the vision and goal of 2035, which is to build our country into a moderately developed country, from a well-off society in an all-round way to a moderately developed country. This is an extremely grand goal. As a teacher who studies economics and finance, I have carefully read the communiqué of the Fifth Plenary Session of the 19th Central Committee, as well as the suggestions on the 14th Five-Year Plan and the long-term goals for 2035. What excites me most is that the per capita GDP will reach the level of moderately developed countries by 2035. Judging from the economic indicators, developed countries have a single indicator, that is, the per capita GDP reaches 12,400 US dollars, which is the lowest threshold of OECD. Of course, it is only a threshold. If you want to become a developed country, you obviously have to meet various cultural, social, legal, regular and spiritual requirements.

  There are 31 developed countries in the world, of course, many of them exceed $12,400, but they are not listed as developed countries because they are not good in other aspects. Environmental conditions, whether men and women are equal, if men and women are not equal, you can hardly say that this is a developed country. If the environment is very bad, the public security is very bad and the order is very chaotic, it is not a country ruled by law, and no matter how high the per capita GDP is, it is not a developed country. Based on culture, society and the rule of law, the requirements are very high, with a total of only 31. Moreover, we have to reach the level of moderately developed countries, which is now more than 10 thousand dollars. According to such a requirement, I calculate that by 2035, we should reach the level of per capita GDP close to 25 thousand dollars, which may be called the economic index of moderately developed countries by current standards. At the same time, in the humanities, society, environment, the rule of law and other aspects, we should comprehensively promote the modernization of China society, including the modernization of state governance, which are among the connotations of moderately developed countries.

  There are still 15 years from today to 2035, and the complexity of the difficulties we may face in these 15 years may exceed that in the past 40 years. Because today’s international environment has become very complicated, how can we deal with it? It is necessary not only to promote economic development, but also to cope with the changes in the complex international environment. Therefore, in this process, new requirements are put forward for the talent training of higher education in China.

  In the process of moving from a well-off level to a moderately developed country, we have to overcome a major trap, which is called the "middle income" trap. The so-called "middle income" trap is that it is difficult for some emerging economies and some countries to cross the threshold of $12,400 in the process of economic development. Or even if it is crossed, it is difficult to stay in the ranks of developed countries for a long time because of various factors, such as talent, science and technology, currency devaluation and insufficient innovation ability, and it is a common phenomenon.

  How did China overcome the "middle income" trap during the Tenth Five-Year Plan period? To lay a solid foundation for us to rush to moderately developed countries is what we must think during the "14 th Five-Year Plan" period. Of course, the most important thing here is that we must adhere to the general direction of reform and opening up. Only by adhering to reform and opening up can China have the opportunity to rush to moderately developed countries; Second, we must take the road of market economy; Third, we should adjust some economic development strategies according to the changes at home and abroad, such as the dual-cycle development strategy. We should promote domestic demand, promote economic development, and promote economic development through the growth of domestic demand, then the income level of China residents will be improved.

  At the same time, China’s higher education shoulders the responsibility of cultivating talents with high quality that match those of developed countries. What is very important here is its scientific and technological innovation ability, innovation ability and scientific and technological level, and its thinking must not be bound. Once bound, its innovation ability will drop greatly. In many countries, the core of the "middle income" trap is the decline of innovation ability. Higher education cannot provide high-quality talent support for developed countries, so it declined, so it came back. Higher education in our country shoulders the responsibility of the times and the historical mission. They should have a strong sense of innovation, scientific and technological ability to keep pace with the times, and a sense of responsibility to keep pace with the times. These are all great responsibilities that higher education will face in the future.

  A series of reforms we are doing now are moving in this direction. Thank you all.

On the 10th anniversary of the P series, Huawei launched a "treasure box": subverting the folding screen mobile phone experience

After the large-screen straight-board form of smartphones became popular in people’s lives, it has been a well-developed design for so many years, and in the past two years, there has been almost no gap in configuration. Manufacturers have less and less room to play, and consumers have less and less choice. It is easy to experience aesthetic fatigue.

However, in the past two years, there have also been some very fresh blood in the mobile phone market, that is, a new form of folding screen mobile phone. According to the latest authoritative data released by iResearch, in the context of the continuous decline in the overall shipment of smart phones, the shipment of folding screen mobile phones in China in the past two years is growing, and it is expected that the global shipment of smart phones will rebound in the future.

These data also mean that the folding screen will be the next trend in the mobile phone market, and Huawei has realized the layout in advance before the trend arrives. In the past two years, it has continuously promoted the iteration of folding screen mobile phones.This year’s Mate X2 is already very mature, accounting for nearly 70% of the Chinese folding screen mobile phone market, and has become the absolute leader in the folding screen market.

However, Huawei is not satisfied with this, but hopes to stand higher and fly farther in the future of the folding screen.

On December 23rd, Huawei officially released the first vertical folding screen mobile phone Huawei P50 Pocket, which is Huawei’s new layout in the folding screen market and a new breakthrough on the occasion of the tenth anniversary of the birth of the P series.

First of all, it can be seen at a glance from the appearance that the Huawei P50 treasure box is a stylish and portable folding screen mobile phone, which is folded up and down and has a smaller body.

Huawei’s first longitudinal folding flagship, creating a new generation of water drop hinges to "erase" creases

As a folding screen mobile phone, a foldable screen must be a top priority in design. The Huawei P50 treasure box has innovatively adopted a new generation of water drop hinges unique to the industry, allowing the phone to form a water drop-type screen space at the bend, solving the problem of the fuselage gap in the folded state.

At the same time, Huawei also uses a multi-dimensional linkage lift design in the folding structure, which can push the screen as the screen unfolds and folds, making the folding screen smooth and smooth. The crease problem is also greatly reduced. In actual use, it is almost impossible to feel the many pain points of the previous folding screen mobile phone, allowing the folding screen mobile phone to enter the practical stage.

In addition, Huawei did not focus all its energy on folding design, but still brought a screen with excellent display quality.Equipped with a 6.9-inch flexible inner screen, it supports up to 120Hz smart refresh rate, 442ppi, 1.07 billion color, etc., and adopts a 21:9 ratio, whether it is swiping text information or watching games, it can bring a broader field of vision and a stronger sense of immersion.

This screen is also covered with a new nano-optical film, which can achieve ultra-low screen reflectivity, effectively reducing the impact of screen creases on the visual experience, and will no longer have creases all over the eyes under strong light.

The first double-sided three-dimensional micro-engraving process makes the mobile phone as bright as a diamond, the perfect folding screen flagship for the lady

On the back design, the crystal diamond white color scheme of Huawei P50 treasure box adopts unique double-sided three-dimensional micro-engraving process glass, and engraves 1000 diamond-shaped squares, which can bring reflected light and shadow like diamonds and achieve new aesthetic breakthroughs.

It is not difficult to see from the design of this back case,Huawei P50 treasure box will be a folding screen phone that is highly sought after by female users, allowing female users to hold it in their hands like a vanity case, which is completely different from previous folding screen phones that were mostly male and favored hardcore technology.

It is worth mentioning that the Huawei P50 treasure box also continues the P50 series double ring rear camera scheme in the ID design. The two rings on the top of the back make it clear at a glance that it belongs to the P50 series, which is in the same vein as the P series Vientiane double ring design.

But the difference is that the ring under the Huawei P50 treasure box is actually a delicate round screen.It can conveniently display time, notifications and other information, and can operate main functions such as notifications, schedules, calendars, music, weather, wallet payment, etc. without opening the lid.

HarmonyOS + folding screen ecological alliance makes folding screen easy to use and easy to use

With the blessing of Hongmeng Ecology, the HarmonyOS service card was brought.You can directly open the services of many third-party applications such as Alipay, Autonavi Maps, Meitu Xiuxiu and other third-party APP.These are the ecology and innovation that Huawei has continuously developed in the field of folding screens in recent years, which will eventually make folding-screen mobile phones easier to use.

It is reported that Huawei has taken the lead in establishing a folding screen ecosystem alliance since launching folding screen products in 2019, and through close cooperation with developers, has promoted the adaptation of third-party apps and folding screens.

In addition, based on its strong soft and hard coordination and ecological capabilities, Huawei can also make the inner and outer screens work in perfect relay on the P50 treasure box.

For example, after receiving a notification on the external screen and clicking on the preview, opening the screen will directly enter the notification interface, and the reply message will arrive instantly; while on the phone, it is more convenient. When an incoming call is made, the external screen will directly display the incoming call information. In this case, the screen can be opened to answer directly. The experience is similar to the flip machine in earlier years, and the whole process is very smooth and natural.

Top three-camera module + secondary screen preview, Huawei P50 treasure box can be called a selfie artifact

The most important thing is that the addition of this sub-screen also makes the selfie effect more powerful, you can directly link with the main camera module, preview the picture in real time and complete the selfie, in the 40 million pixel primary color lens + 13 million pixel ultra-wide-angle lens + 32 million pixel hyperspectral lens Under the combination of three cameras, it can bring stronger and more natural selfie image quality, blurring effect, etc., seconds become selfie artifact.

In addition, the Huawei P50 treasure box rear camera module also integrates a 10-channel multispectral sensor, flash, hyperspectral fill light, laser focus sensor, based on the hyperspectral fill light and macro shooting capabilities, Huawei has brought a new shooting gameplay – fluorescence photography.

This function allows users to use the Huawei P50 treasure box in their hands to take beautiful fluorescent pictures that are difficult to see with the naked eye in nature, such as shooting flowers in a dim light environment, you will see a different fantasy world. And with the blessing of the hyperspectral imaging system, Huawei Mirror also brings professional-grade skin detection function. Through AI accurate identification, hyperspectral depth analysis, real-time sunscreen detection, intelligent reminders, and sun protection suggestions are given.

This combination of top-level hardware, innovative interaction, and application ecology has allowed Huawei’s P50 treasure box to truly transform from usable to easy-to-use and easy-to-use, and even endowed it with fashionable attributes through ID design, which is no longer exclusive to hardcore players. This has greatly promoted the further popularization of folding screen mobile phones.

If you have the opportunity to experience the Huawei P50 Pocket, you must give it a try. It may change your previous opinion of folding screen phones.The Huawei P50 Pocket is priced at 8988 yuan and will be officially launched at 18:08 on December 23 in Huawei Mall, major e-commerce platforms, Huawei Authorized Experience Stores, and Huawei Authorized Distributors.

Huawei also launched a broken screen service treasure and an extended service treasure for the P50 treasure box. The broken screen service treasure covers the inner and outer screens, and you can enjoy a low-cost service fee to change the screen after the broken screen. You can also get a battery renewal service within two years when you buy with the new machine. The extended service treasure is to extend the one-year warranty service period for the equipment host on the basis of the standard warranty service period. Users who need it can go to Huawei malls, retail stores, and service stores to buy with the new machine.

5G commercial start-up operators push various promotions to further reduce the price of 5G mobile phones

  CCTV News:Personal mobile phone users will be able to use the 5G communication service from today (1st). In order to welcome the official commercialization of 5G, the three major operators have also launched a variety of promotional measures in combination with the newly launched 5G package.

  Yin Shaochun, Deputy General Manager of China Unicom Marketing Department:We are now carrying out the package reservation activities for old users through the mobile phone business hall. The current policy is that there will be a 30% discount for those who have been online for more than three years, and a 20% discount for those who have been online for less than three years.

  

  Lu Liangjun, Deputy General Manager of China Telecom Marketing Department:China Telecom launched cloud VR, cloud games and ultra-high-definition video when it was officially commercialized. It combines the characteristics of high traffic of 5G with the characteristics of cloud network integration of China Telecom, which will bring users a better audio-visual experience.

  China Mobile said that it will further reduce the price of 5G mobile phones and lower the threshold for users to replace 5G mobile phones.

  Shou Jianguo, Deputy General Manager of China Mobile Marketing Department:In the second quarter of next year, we will launch a mobile phone with a gear of 2000 yuan, and in the fourth quarter of next year, it is possible to launch a mobile phone with a gear of 1000 yuan. Then, in order to further lower the threshold for customers to replace 5G, China Mobile has also launched supporting preferential activities such as installment purchase of 5G mobile phone credit and worry-free replacement.

  The person in charge of the operator also said that at present, 5G is still in the initial stage of commercialization, and the network coverage is not perfect. There may be some problems in the use process. With the gradual advancement of commercialization, the construction of 5G networks will be accelerated.

Astronomers’ research shows that if there is no sun, the average surface temperature of the earth will drop to below-17.78 degrees Celsius in a week, and it will drop to-73.33 degrees Celsius in a year. Most plants will die in a few weeks, and then most life will disappear because of the disappearance of the sun, and everything will be dead.

  Now we know how important the sun is to us! However, something unfortunate happened. Recently, foreign scientists’ research on the metal abundance of the sun shows that we may overestimate the life of the sun by one billion years, and the sun may die one billion years earlier than we expected.

  Elemental abundance controls the sun’s life gate

  It is understood that scientists have previously deduced that the life of the sun is about 10 billion years based on the standard solar model that ignores the rotation effect, which is a theoretical value simulated by the stellar evolution program, not a real value. And this value only refers to the central hydrogen combustion life in the theory of star evolution.

  "This is not to say that the sun really can only exist for 10 billion years. The accurate statement should be called the main sequence life of the solar model. In theory, the sun will become a red giant in about 10 billion years, but it still exists and will emit more sunlight. " Associate Professor Yang Wuming from the Astronomy Department of Beijing Normal University told the Science and Technology Daily reporter.

  He said that there are many preconditions to get the theoretical value of 10 billion years, and it is necessary to assume the initial element abundance of the sun and the physical process inside the sun. The life of the solar model is different with different initial element abundances. Because it is impossible to really get the initial element abundance of the sun and determine its internal physical processes, the life of the sun and even other stars cannot be accurately estimated.

  Twenty years ago, astronomers’ direct and indirect measurements of the sun showed that the metal abundance of the sun was around 1.8%; However, the latest solar spectrum measurement shows that the metal abundance of the sun is only 1.3%, which is far lower than the previous measurement results, and correspondingly, the life of the sun will be reduced by 1 billion years.

  The so-called solar metal abundance is the general term for the abundance of solar elements except hydrogen and helium. This metal is different from what we usually call metals. Because the contents of hydrogen and helium in the sun account for the vast majority, astronomers call all the heavier elements in the sun "metals". Although the content of these metals is small, it affects the fate of the sun.

  Because the electrons of metal elements easily absorb photons, which hinders radiation, the higher the metal abundance of the sun or star, the higher the opacity. The opacity of the sun or star is closely related to its life, temperature, brightness and other properties. Sani Vaniotch, a physicist who studies solar metal abundance at Stockholm University in Sweden, said that a very small amount of metal is enough to completely change the behavior of a star, and metal abundance can basically tell you how the star will die.

  Influence of atmospheric model on solar lifetime estimation

  The solar spectral measurement used in the latest research usually means that astronomers get the spectral lines of all measurable elements such as hydrogen, carbon, nitrogen, oxygen and iron through solar spectral analysis, and then compare them with the spectral lines given by the solar atmospheric model. When the two are consistent, the abundance of elements such as hydrogen, carbon, nitrogen, oxygen and iron used in the atmospheric model is considered as the element abundance of the solar photosphere. "However, this method cannot obtain the relative abundance of inert gases such as helium, neon and argon. The abundance of helium on the surface of the sun can only be inferred by helioseismology. " Yang Wuming said.

  After the latest measurement results come out, many people are wondering: Why is there such a big difference between the solar metal abundance measured before and after?

  In this regard, Yang Wuming explained that the old solar metal abundance was derived from the one-dimensional atmospheric model of local thermal balance combined with the observed spectral lines; The new solar metal abundance is derived from the three-dimensional atmospheric model of non-local thermal balance combined with the observed spectral lines. The old one-dimensional atmospheric model is considered to ignore many physical factors. Some scientists think that the new atmospheric model is closer to the real situation, and it is the improvement of the atmospheric model and the update of the transition probability data of atoms and molecules that cause the difference in the abundance of old and new metal elements.

  In the evolution of stars, if other conditions remain unchanged, the decrease of metal abundance will lead to the energy generated by the central nuclear reaction radiating outward more easily. However, the energy tends to radiate outward, which will cause the star to contract more easily and increase the density and temperature of the center of the star. More importantly, the increase of density and temperature will accelerate the hydrogen combustion rate, which will lead to the shortening of the total time of central hydrogen combustion, that is, the main sequence life of the solar model will be shortened. However, if other conditions change, such as the increase of hydrogen abundance or the influence of the sun’s rotation on its evolution, then the aforementioned life reduction does not exist.

  So, how to verify which method is more correct in the future?

  In Yang Wuming’s view, the answer to this question lies in which metal abundance measurement is more accurate and whether the helioseismology inversion result is reliable. Only by giving the correct abundance of solar elements can we determine how long the life of the sun is. If we can give a new solar model of gold abundance consistent with the helioseismology inversion results, all related problems will be solved.

  Life geometry is related to the theory of stellar evolution.

  Chen Pengfei, a professor at the School of Astronomy and Space Science, Nanjing University, said that he was inclined to think that the initial life span of the sun was correct, and the life span of the sun would not be reduced by one billion years. "For several reasons, I prefer to think that the original model is correct: first, the measurement results of metal abundance in the solar wind by satellites support 1.8%; Secondly, the density of photosphere on the surface of the sun is high enough, so it is reasonable to adopt the approximation of local heat balance model in the past; Thirdly, the new model takes into account the inhomogeneity of the solar atmosphere, which is indeed an improvement, but it also ignores other factors, such as the influence of magnetic field; Fourth, to take a step back, even if the results of the new model are correct, because the distribution of metal abundance may be uneven, the metal abundance on the surface of the sun may be different from that inside. " Chen Pengfei said.

  At the same time, Yang Wuming also agrees that the initial solar life is correct. He said that the life of the sun has not been overestimated by 1 billion years, and that the life of the sun is overestimated because only the reduction of metal abundance is considered. When the influence of hydrogen abundance increase and rotation on the evolution of the sun is considered, the life of the sun will not be reduced.

  However, the astrophysicist Martin asp Lund of the Australian National University insists that the 1.3% solar metal abundance is correct. He said that all aspects of astronomy will be affected, and an accurate understanding of the evolution of stars has laid the foundation for almost everything.

  So, if astronomers do overestimate the life of the sun by one billion years, what theories need to be revised?

  In Yang Wuming’s view, if the life of the sun is really overestimated by 1 billion years, it shows that the theory of stellar evolution established by astronomers before is not complete, so they need to re-examine the theory and model of stellar evolution established before. For example, the standard theory of star evolution ignores the influence of star rotation, but in fact all stars are rotating. We have reached the time when we need to seriously consider the influence of rotation on the evolution of stars. Astronomical research on star clusters and galaxies depends on the theory of stellar evolution to a certain extent. If the theory of stellar evolution is wrong, the previous understanding of star clusters and galaxies needs to be adjusted.

Rafinha: I want to stay in Barcelona for many years. Red and blue new hairstyle? I had this intention long ago.

Live on May 21 ST, after Barcelona won the championship four rounds ahead of schedule, it lost to Royal Society 1-2 in today’s game. After the game, Rafinha was interviewed by beIN Sports.

More than 88,000 spectators witnessed Barcelona winning the Cup, and the Brazilian striker couldn’t hide his excitement: I want to stay in Barcelona for many years.

In addition, Rafinha dyed her hair red and blue, to which he explained: My new hairstyle? Araujo and I had this idea before in Gated, but I didn’t want to do it in that game, because we still needed a victory to ensure the championship.

Rafinha also talked about wearing the Brazilian flag to celebrate: whenever possible, I will carry the national flag with me. This is the place where I was born, and the Brazilian people love me very much. At such a special moment, they will always be with me.

Rafinha has played 47 games this season, contributing 10 goals and 12 assists.

Pull your hips! Li Kaier was naturalized and thoroughly sleepwalked, and two points and five points made three noes, which can drive the China team?

On April 22nd, Beijing time, did the China Men’s Basketball Team really consider returning the goods? The Timberwolves are now 0-3 behind the Nuggets, and Kyle Anderson once again gave a depressed performance in the crucial third game.

Since Li Kaier heard the news that he might be naturalized by the China men’s basketball team, Anderson has been in a daze recently. Except for the infighting being punched by Gaubert, he played very badly in every game. In the face of the Nuggets, he was the absolute core of the bench. He scored 1 of 7 in 29 minutes, but only got 2 points, 2 rebounds and 5 assists, as well as 2 mistakes and 5 fouls.

In 29 minutes, 2 minutes and 5 fouls, Anderson’s performance was too low, and the positive and negative values were the lowest in the audience. After three playoff games, his three positive and negative games were all ranked in the bottom four of the team. In the first game against the Nuggets, he made 5 of 11 shots and finally got 11 points, 1 rebound and 3 assists. His performance was not very good. The team was defeated by nearly 30 points. At that time, Anderson’s play was questioned by many people.

In the second game against the Nuggets, he played well. He scored 10 points, 7 rebounds and 4 assists in 4 out of 5, but there were also 4 fouls. More importantly, the team lost the game again. To be honest, Anderson really didn’t make any contribution in this game today. The whole game was completely sleepwalking in offensive and defensive aspects, which can be said to be almost every game.

It can be said that you used four words to describe Anderson’s performance in this game, which really means no speed, no breakthrough, no attack and no rebound. The defense is still as hard as ever, and the organization of the whole team is more serious, but that’s all. The problem is that you don’t have the advantages mentioned above. You can’t even carry the Timberwolves. Can you carry the China men’s basketball team? He stood beside Wolves with Gaubert, Downes and Edwards, and a veteran Conley in the NBA.

It’s not the same when you come to the China men’s basketball team. The weakened version of Gaubert qi zhou, the absolutely all-round scaled-down version of Downs Zeng Fanbo, Edwards and Zhang Zhenlin standing next to you are nothing to compare with. How can the defender Guo Ailun compare with Conley? Can you move the China men’s basketball team? Li Kaier, who has none of these advantages, is of great significance and value to the China men’s basketball team? It seems that he won’t play ball since the news of naturalization came. I wonder if he wants to finish the game early and go through the formalities? The heart is gone. Where’s the Timberwolves? Or is the ability not so good?
