　　Xinhua News Agency, Guiyang, July 3 rd Title: Revealing the world’s largest "pot cover": 4,450 reflection units spell out the world’s largest and strongest "Eye of the Sky"

　　Xinhua news agency reporter

　　Remember what the "pot cover antenna" looks like?

　　On July 3, 2016, the world’s largest "pot cover" with a diameter of 500 meters was erected in Guizhou karst tiankeng.

　　It is the 500-meter spherical radio telescope, the largest and most powerful single-aperture radio telescope in the world.

　　It is called "Eye of the Sky", which is used to listen to the sounds in the depths of the universe and observe the mysteries of the universe.

　　Start with Xue Huadian on old TV.

　　When the old TV can’t receive the signal, the screen is not blank, but Xue Huadian is flashing. In fact, these Xue Huadian are electromagnetic wave signals, including radio emission from space.

　　In 1933, scientists in bell laboratory accidentally discovered the stable radio emission from the center of the Milky Way with a highly sensitive receiver, which opened the door to radio astronomy.

　　Anyone who has used the "lid antenna" knows that the larger the lid aperture, the clearer the TV picture. For radio telescopes, the larger the aperture, the farther you can see. Radio astronomers all over the world are pursuing to build a larger-caliber "pot cover" to improve the sensitivity of radio telescopes.

　　Peng bo, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences and deputy manager of the 500-meter spherical radio telescope project, said that the radio telescope had been short of funds at the beginning of its design and construction, but scientists were unwilling to reduce its caliber no matter what it was reduced.

　　"Space is mixed with all kinds of radiation, and distant signals are like cicadas in thunder, and there is no super-sensitive ‘ Ear ’ I can’t tell it at all. " Nan Rendong, chief scientist and chief engineer of the 500-meter spherical radio telescope project at the National Astronomical Observatory of the Chinese Academy of Sciences, said.

　　Previously, the most sensitive radio telescopes in the world were the 100-meter telescope in Bonn, Germany and the 300-meter telescope in Arecibo, USA. The former can move and "shake its head", while the latter is built with the help of karst potholes on Puerto Rico island.

　　At the 1993 International Radio Union Congress, astronomers from 10 countries, including China, proposed to build a new generation of radio "big telescopes", eager to go back to the original universe and solve many difficult problems in astronomy before the radio wave environment was completely destroyed.

　　"Building the world’s first large-caliber radio telescope is the dream of teacher Nan Rendong and several predecessors, which embodies the ambitious ambition of China astronomers." Peng bo said.

　　At the end of 1995, more than 20 universities and research institutes in the United Nations of Beijing Observatory set up the China Promotion Committee of Radio "Large Telescope", and put forward the karst engineering concept of building a spherical reflector, namely "Arecibo antenna array", by using Guizhou karst depression.

　　Since then, scientists in China have further promoted the concept of karst and proposed to independently develop a new karst unit, namely a 500-meter spherical radio telescope.

　　In order to set up a new generation of radio "big telescopes", scientists have turned over the karst mountain areas in Guizhou through satellite remote sensing. Peng bo recalled that at that time, the Observatory commissioned two institutes to conduct independent search and select from more than 300 candidate potholes. As a result, Dawodang, located in Pingtang County, Qiannan Prefecture, got the highest score twice.

　　The conditions provided by natural karst potholes in Guizhou have always been the most unique and the largest and strongest foundation for China Radio Telescope in the world.

　　Not just a big circle — — What is the strength of China Radio Telescope?

　　Whether you are near a large radio telescope, climbing the observation deck on a nearby hill or watching a virtual reality video, you can intuitively feel its first feature — — Big. Scientists describe it as a "giant eye for watching the sky".

　　Wang Qiming, chief engineer of the 500-meter spherical radio telescope project at the National Astronomical Observatory of Chinese Academy of Sciences, said that more than 10,000 tons of steel were used only for the ring beam, cable net and six towers supporting the feed cabin.

　　"The total reflecting surface of the telescope is 250,000 square meters, which is equivalent to the size of 30 standard football fields. Although the reflective panel is only 1 mm thick, it also uses more than 2,000 tons of aluminum alloy. " Wang Qiming said.

　　However, the large radio telescope is by no means a "stupid" metal pile, it is the most sophisticated astronomical instrument. Due to the adoption of the feed platform with optical, mechanical and electrical integration and the secondary adjustment of the parallel robot in the feed cabin, it can realize millimeter-level pointing tracking without rigid connection between the feed and the reflecting surface, ensuring accurate gathering and monitoring of weak radio signals in the universe.

　　The construction technology of the large radio telescope is also improving. Wang Qiming said that due to strict requirements, this big scientific project has promoted the improvement of equipment manufacturing capabilities in many fields:

　　— — The cable net with active reflection surface has the characteristics of high elasticity, tensile resistance and fatigue resistance, and its ultra-high stress amplitude of 500 MPa is 2.5 times that of the national standard;

　　— — More than 2,000 hydraulic actuators that help the reflector to be displaced can achieve accurate positioning and coordinated movement through expansion and contraction, and can also report their own state information to the control system to meet the movement requirements such as timely tracking and source change.

　　— — Dynamic optical cable, which undertakes the mission of transmitting all kinds of data and information, can withstand repeated bending, winding and torsion and other mechanical properties and harsh natural environment tests.

　　"Our original design concept originated from the Arecibo telescope in the United States. But compared with Arecibo, the active reflector system is our biggest innovation. " Peng bo said that the cable net structure of a large radio telescope can change with the movement of celestial bodies, driving 4,450 reflecting units on the cable net to form a 300-meter instantaneous paraboloid in the direction of radio power supply, which greatly improves the observation efficiency.

　　Arecibo telescope is a fixed telescope, which can only scan a 20-degree strip area in the sky by changing the position of antenna collapse. The active reflector allows the China Radio Telescope to have a wider observation range, covering 40-degree zenith angle.

　　The working frequency of large radio telescopes is relatively wide. Peng bo said that the feed cabin is equipped with a multi-band and multi-beam feed and receiver system covering the frequency of 70 MHz ~ 3 GHz.

　　Zheng Xiaonian, deputy director of the National Astronomical Observatory of the Chinese Academy of Sciences, said that the German Bonn telescope with a diameter of 100 meters was once called "the largest machine on the ground", and the sensitivity of the China Radio Telescope was improved by about 10 times. The 300-meter-caliber Arecibo telescope in the United States has been unsurpassed for more than 50 years. Compared with it, the comprehensive performance of China Radio Telescope has been improved by about 10 times.

　　Take root in the karst sinkhole and look at the deep space of the universe

　　"Like other radio telescopes, the two main scientific goals of the China Radio Telescope are to patrol the neutral hydrogen in the universe and observe pulsars. The former is to study the large-scale physics of the universe to explore the origin and evolution of the universe, and the latter is to study the material structure and physical laws in extreme States." Zheng Xiaonian said.

　　The earth’s atmosphere leaves two windows for human beings to explore the universe, one is optics and the other is radio. For astronomers, if the optical telescope is a microscope, then the radio telescope is a CT machine, which can obtain the ultra-fine structure of celestial bodies.

　　"There are seven sets of receivers, because the frequency of observation in different bands is different, and the observation and research goals are different." Peng bo said that in the eyes of large radio telescopes, the universe and cosmic celestial bodies are a three-dimensional presentation.

　　For more than half a century, the energy collected by all radio telescopes in the world has not turned a page, and the joining of China Radio Telescope will greatly accelerate this speed. And the energy collected means the amount of information to interpret the mysteries in the depths of the universe.

　　"Since the birth of the radio telescope, humans have discovered about 2,500 pulsars. If the working hours of the China Radio Telescope are all used to observe pulsars, it is expected to double this number within one year." Peng bo said that pulsars can be used for pulsar navigation, pulsar timing array and other application targets.

　　Nan Rendong believes that large radio telescopes may also find some unprecedented pulsar phenomena, such as a pulsar paired with a black hole, which may produce a breakthrough theory.

　　Every little progress in the development of physics is accompanied by great difficulties and twists and turns. But at every stage of human civilization progress, physics has always stood at the forefront of liberating productive forces. Peng bo said that scientists used Arecibo telescope to discover gravitational waves and won the Nobel Prize in physics, while China Radio Telescope provided a great opportunity for natural science, especially physics-related fields.

　　"The answer is yes to whether the large radio telescope that the public is very concerned about can be used to find extraterrestrial civilization." Peng bo said that it is a weapon to detect exoplanets, especially terrestrial planets. Because of its improved sensitivity, it can see farther and fainter celestial bodies. By detecting interstellar molecules and searching for possible interstellar communication signals, the probability of finding extraterrestrial civilization is 5 to 10 times higher than that of existing equipment.

　　On July 3rd, after the installation of the feed cabin and the reflector panel was completed as planned, the large radio telescope will be debugged for more than two months, and it will be officially completed and put into use at the end of September. However, in order to optimize all functional parameters, it needs to be continuously debugged and improved in two or three years of observation.

　　"After the completion of the large radio telescope, it will become the ‘ Sharp weapon ’ To maintain the status of world-class equipment in the next 10 to 20 years. " Zheng Xiaonian said, "I hope that China scientists will use it to produce results as soon as possible." (Note holder Qi Jian; Participating reporters Wu Jingjing, Hu Xing and Yang Weihan)

What is culture? Writing is "recording, expressing and commenting", while culture is "analysis, understanding and tolerance". The characteristics of culture are: history, content and story. Many philosophers, sociologists, anthropologists, historians and linguists have been trying to define the concept of culture from the perspective of their respective disciplines. The above is a slightly official interpretation. I only interpret the word "culture" from a personal point of view or a biased point of view. Culture is root-seeking and positioning!

Searching for roots means knowing where you come from.

As individuals, seeking roots means knowing who our ancestors are, and then we have some traditional clan genealogy. Who are our parents, grandparents and great-parents? I have been looking for it all the time. In the past, some people said that this person is well-rooted, well-born, and there are no unscrupulous people in the clan for three generations. He is a reliable person. What I am talking about here is his origin. Some big families have also formed their own clan culture. For example, Zeng Guofan once left a 16-character proverb: "If you are frugal, you will prosper, and if you are diligent, you will be healthy; Be diligent and frugal, and never be poor. " Manage the family by frugality.

Zeng GuofanI have always asked my family to live frugally and stay away from luxury. When he met aristocratic men in Beijing who were blindly extravagant, corrupt and profligate, he refused to let his children live in Beijing. His original wife has been leading her children to live in their hometown in the countryside, and the plaques of "Xiangfu" and "Houfu" are not allowed to hang outside the door. Zeng Guofan demanded that "we should be honest and frugal, and swear not to send any money to our families." My wife has no spare money at home, and cooks and textiles herself.

Diligent in learning. In addition to "frugality", Zeng Guofan’s other requirement for his children is "diligence". Zeng Guofan insisted on writing letters to his children, correcting poems for them and discussing various problems in his studies and life. He wrote to his son, Ceng Jize, asking him to dress neatly after getting up every day, to greet his uncle and uncle first, and then to clean all the houses before sitting down to study, practicing 1,000 words every day.

Zeng Guofan also urged his family to keep studying every day, and drew up a strict study plan for the whole family many times: "My family’s men are indispensable in reading, writing and writing. Women are indispensable for clothing, food, coarse (work) and fine (work). "

Attach importance to family education. Zeng Guofan had three sons and five daughters, and his youngest daughter, Ceng Jifen, lived to be 91 years old. In 1875, Ceng Jifen married Nie Jia in Hunan. Zeng Guofan stipulated that each daughter’s dowry should not exceed 200 taels of silver when she gets married, and there is also a homework list written by her father. Zeng Guofan wanted to train his daughter to be a diligent housewife. In fact, her daughter did better than her father expected.

A good clan culture can make a family flourish, as well as a nation. The nation is talking about history. China has a long history of 5,000 years. China people are honest, hardworking, brave, simple and intelligent, and there are many cultural classics handed down, such as the Book of Changes, the Tao Te Ching, the Analects of Confucius and Mencius. All dynasties pay attention to cultural inheritance, and all dynasties pay attention to the compilation of historical books, such as Zi Zhi Tong Jian, which we are familiar with. For this inheritance that we should criticize, we should take what we have and give up, publicize it well, and abandon what does not meet the needs of contemporary society. China is also known as the country of etiquette, especially Confucius has always emphasized the rites of Zhou, and people pay attention to etiquette when they communicate with each other. The younger generation should salute when they see their elders, and the lower level should salute when they see their superiors. Confucius has always emphasized benevolence, righteousness, propriety and wisdom, including the wisdom of the sages. If we don’t pay attention to inheritance and study, we won’t know our own culture. Then you don’t know your position.

As a country, it also needs cultural orientation, such as the 24-character socialist core values: prosperity, democracy, civilization, harmony, freedom, equality, justice, the rule of law, patriotism, professionalism, honesty and friendliness.

Culture is positioning.The Tang Priest has a classic sentence in Journey to the West: The poor monk Tang Xuanzang came from the Tang Dynasty in the east and went to the Western Heaven to worship the Buddha for Buddhist scriptures! This sentence illustrates the problem, always know.Who are you? Where are you from? What are you doing? Where are you going? This is positioning.I’m Tang Xuanzang: I’m invited by the king of Tang to learn from the scriptures. My mission is to learn from the scriptures and constantly beat myself. I can’t complain about the superior king of Tang, the imperial court or bow to difficulties. At present, some Chinese people, as Chinese people, complain about the country all day, especially abroad, and forget who they are. Eating China’s water and food, instead of cursing the motherland and cursing mothers, such people are called unfilial descendants and forget their roots, but if they are also like this abroad, their nature will change, that is, the scum of the nation will become fake foreign devils. Especially in today’s epidemic, some clowns are jumping up and down and gossiping.

where i was from?The word "filial piety" is interpreted in Shuo Wen Jie Zi as being obedient to the old. Performance is inheritance, inheritance, and the premise of inheritance and inheritance is recognition, and recognition contains the meaning of respect and affirmation. Personally, we should recognize our parents, that is, respect and affirm their advantages, and our lives are subject to their parents, so we should know how to be grateful; The traditional genes of parents should be recognized, such as hard work, kindness and other good things, of course, they should be critically inherited and objectively evaluated, and they should be divided into two and not go to extremes. A family is like this, and so is a country and a nation. Don’t always scold your mother, you are not filial, and the luck of unfilial people is not much better! Because some genes in your parents come to an abrupt end on you, denying your ancestors, and your soul track has changed. . . . .

When it comes to filial piety, it means recognition first, and recognition at its peak means worship, and worship means reverence. China’s gods are all human beings, such as Fuxi, Guan Gong, Zhao Gongming, Yue Fei, etc. If we worship Guan Gong because of his loyalty, our fate will only change if we become such a person. Of course, more people pray for Guan Gong to protect and take care of themselves, because he has skill and he is a god, but the prerequisite for this kind of god to bless you is that you need it. We worship Guan Yu, and more importantly, we should straighten our mentality, learn to let go and become loyal people. When we worship a bodhisattva, we learn to be like a bodhisattva, learn to help others, and there is a saying that helping others is actually helping ourselves. The ancients paid attention to helping others and helping themselves. What kind of person you worship must be, so it will work, otherwise you can only be given a sentence: don’t burn incense at ordinary times, cram for the Buddha’s feet temporarily. Buddha can’t help you if you don’t do a good job in the early stage and worship Buddha temporarily.

Culture includes a lot of contents, too. Culture is condensed in the material and dissociated from the material. The history, geography, customs, traditional customs, lifestyle, literature and art, code of conduct, way of thinking and values of a country or nation that can be passed down are endless. Let’s stop here today! If you are not finished, please leave a message in the comments section!

Is it true that "birds fly away with husband and wife, and people are virtuous and have high character"? People will have different moods in different environments, do different things, and their thoughts will change. It is said that many astronauts, and foreign astronauts, look back in space and see that the earth is so small. In an instant, I also feel that human beings are small, even forgetting the nationality, and I hope that the "global village" will unite. Challenging the mysterious space together, although few astronauts talked about it, according to the network, most astronauts and foreign astronauts should have the same mood at that time.

Many people say that looking at the earth from space is a word "beauty". In fact, I think it should be more thorough. Some people think that if leaders of various countries go to space to see the earth, there may not be so many disputes. The idealist’s idea is really beautiful. "A leopard cannot change his spots." It’s not who is slipped into space that can change the world pattern. The greed, desire and the law of the jungle of human nature can only become more and more obvious. How can it become more and more noble? People are not gods. If human beings could have a bigger pattern, the world would have been in harmony. Maybe all mankind will be promoted to the first level of civilization through cutting-edge technology.

The greedy desire that human beings can’t change is just like dogs can’t change eating shit and cats love eating fish. It’s hard to hear, but it’s true. Humans always think that the world belongs to me, and they are always willing to position themselves as masters and creators, so their possessiveness is very strong. As long as they rule a country or rule the earth, everything on the earth is not ours. Perhaps all this is not human’s original intention. Humans can only control their own behaviors and desires, but can’t decide higher-level things at all. In fact, it is God’s will that created human beings and human nature, which cannot be easily changed by human beings. In fact, we are more like the "turkey" in the TV series "Three-body".

Maybe you think I’m talking nonsense, but isn’t Einstein talking nonsense? Does Yang Zhenning, a Chinese scientist, also talk nonsense? They all tend to be God-like creators, so I said that there is no problem with the existence of God. When I say providence, I mean God! Although Einstein and China’s Yang Zhenning are both great scientists and physicists. Celebrities, maybe they are just idols of human beings, with a little more ideas. As carbon-based human beings, we have not yet broken through the first-class civilization of the universe. How can you see through so many things? Perhaps, as I said before, this phenomenon is called a myth before the problems that human beings can’t solve.

We pay attention to science in everything, but how did Einstein and Yang Zhenning get the first driving force before the Big Bang in the universe? That’s why everyone is more inclined to have a creator. Maybe the first driving force of the universe is naturally formed, and what about the driving force of natural release? Personally, I think that life on our earth basically belongs to carbon-based life. The study of all the stars and various phenomena in space is only in one point to observe the whole universe. If we humans move towards the first level civilization, we may know more mysteries in the universe and space.

For the vast mysteries of the universe, human beings are nothing more than children picking up shells at the seaside. It may be a joke to look back at human science when we enter the next level of civilization, because all phenomena of celestial bodies are just guesses, so we can only rely on guesses. If a policeman solves a case by guessing, then we all know that this is nonsense. Isn’t it nonsense for a scientist to guess? Therefore, I think that after the arrival of silicon-based life, the theories of these scientists are all fart or even worthless. At least silicon-based life can go to danger in person and engage in scientific research in space.

Silicon-based life is more suitable for all kinds of harsh environments, and perhaps no oxygen mask is needed at all. I think these great scientists live by guessing there, so it is better to study life and make human life stronger and wiser. Only we are strong. We can conquer a more powerful universe. Humans may not understand it, but human wisdom has developed artificial intelligence robots, which will not be tired or sleepy. Maybe artificial intelligence will tell us in the future.

According to the Survey data in November, Windows 11 is gradually approaching to achieving two-digit market share. The company is based on the latest data of 60,000 Windows 10 and Windows 11 computers. There are currently 8.6% of the computer running Windows 11, 3.8% higher than last month.

Windows 10 version 21H2, this latest version of the operating system starts to be launched on PCs that are not qualified to use Windows 11, this version also appears in the view of Adduplex this month. By the end of November, its market share is 3.7%, and is currently in Windows 1022 (11%), Windows 10 20H2 (31.8%) and Windows 10 21H1 (36.8%).

Microsoft has repeatedly expressed that it will accelerate Windows 11, which in facts also show their attitude, Win10 is already in the past, and Windows 11 is their focus.

"Based on the active promotion update experience and user feedback we have seen so far, we advance the promotion of the promotion than our previous expectations, and now make Windows 11 upgrades more widely provided to eligible Windows 10 devices," Microsoft WINDOWS service and delivery executive John Kelps said.

It is worth mentioning that Microsoft has indeed expanded the WINDOWS 11 push, as long as your device meets the standard, you can upgrade free.
