What are the best technologies in China?

1, the world's largest radio telescope FAST

FAST radio telescope is the largest radio telescope in the world (full name is 500-meter spherical radio telescope, referred to as FAST).

Fast is really awesome! To what extent are cattle? Let's look down

FAST built the world's largest single aperture radio telescope by using the potholes in Guizhou karst area as the telescope site, with the signal receiving area as large as 30 standard football fields. The imagination and grandeur of this project are shocking!

At present, the FAST project has entered the final stage and is expected to be put into use in September this year. Scientists and engineers in China designed and built this "Eye for Watching the Sky", which used a total of 4,450 lenses with a total weight of over 2,000 tons, which will become a new technological miracle in China and even the world.

If this is not enough, then we might as well compare it horizontally. Compared with the 100m telescope in Bonn, China, the sensitivity of FAST is improved by about 10 times. Experts say that FAST will maintain its status as a world-class device in the next 20-30 years.

2. "Artificial Sun" nuclear fusion device

The energy problem is one of the main topics facing mankind, and the Paris Agreement on climate change has just been signed. How to provide sustainable and clean energy for mankind? The "artificial sun" project is to find the answer to this question. Maybe many people don't know what nuclear fusion is, so they always know nuclear fission, right? The nuclear power technology used by mankind now is the principle of nuclear fission. But nuclear fusion is better than nuclear fission. Why cows? The fundamental reason is that it has three advantages:

(1) Nuclear fusion releases more energy than nuclear fission.

(2) There is no high-end nuclear waste, which will not cause great pollution to the environment.

(3) Adequate fuel supply. There are 654.38+ trillion tons of heavy hydrogen on the earth (every 654.38+0 liter of seawater contains 30 mg of deuterium, and the energy generated by the fusion of 30 mg of deuterium is equivalent to 300 liters of gasoline).

This means that once the nuclear fusion is successful, it can not only greatly reduce the energy cost, but also be environmentally friendly and the fuel supply is extremely sufficient. Therefore, this technology will be revolutionary for energy!

As a major national scientific project, the "Artificial Sun" thermonuclear fusion device (EAST) was established in 1998, which took 8 years to build and cost nearly 200 million yuan. On September 28th, 2006, it was successfully discharged for the first time in Hefei, Anhui. After that, the development of the experimental device won the first prize of national scientific and technological progress in 2008. The successful operation of EAST has been highly praised by experts at home and abroad. They praised "EAST is an extraordinary achievement in the world fusion engineering and an outstanding achievement and an important milestone in the development of fusion energy in the world".

At present, the International Thermonuclear Experimental Reactor (ITER) project jointly undertaken by the European Union, the United States, Japan, Russia, China, South Korea and India is one of the largest and most influential international scientific and technological cooperation projects in the world. The total investment of this project is several billion euros, with China's investment accounting for 9%. Although Dongfang is smaller than ITER, it uses advanced technology similar to ITER. More importantly, EAST was put into trial operation at least 10 to 15 years earlier than ITER, which will accumulate valuable experience for ITER plan.

If the Oriental Project is finally successful, mankind will have inexhaustible clean energy like the sun.

3. Shanghai synchrotron radiation light source device

Shanghai Light Source Project is located in Zhangjiang Hi-tech Park, Pudong, Shanghai. On June 7, 2004, the proposal of Shanghai Light Source Project was officially approved, with a total investment of 654.38+0.24 billion. 201010/9, Shanghai light source project passed the national acceptance. What kind of project is Shanghai Light Source? Generally speaking, Shanghai Light Source is the first third-generation synchrotron radiation device independently developed by China. The synchrotron radiation it produces can see the structure of cells, organisms or materials.

For example, everyone has taken X-rays in the hospital, and we can clearly see the internal situation of the human body that is invisible to the naked eye, and synchrotron radiation is very different from hospital X-rays.

Its brightness can reach tens of billions of times that of X-rays we usually use, enabling people to observe the microscopic world of matter on atomic and molecular scales. Because of this, restoring the fine cultural relics of the Forbidden City, analyzing the complex mechanism of the virus, and building the high-strength shell of the high-speed rail … these seemingly unrelated fields can all be completed with the help of this magical light.

4. Daya Bay Neutrino Laboratory

The experimental facility of Daya Bay reactor neutrino was built in a cave near Daya Bay nuclear power plant in Guangdong, and its goal was to detect neutrinos, a natural product of nuclear power plant reactors when generating electricity. In 2003, researchers from Institute of High Energy Physics, Chinese Academy of Sciences put forward the idea of searching for the third oscillation of neutrinos by using a large number of neutrinos produced by Daya Bay nuclear reactor group in China. On March 20 12, the laboratory announced the discovery of a new neutrino oscillation mode, which was an important physical achievement of the birth of China and was called a milestone in neutrino physics.

Experts said that this achievement will help solve the "mystery of antimatter disappearance" in the universe. According to the big bang theory, the universe originated from a big bang about137 billion years ago. At the beginning of the universe, energy was transformed into as much positive matter and antimatter. When these two substances meet, they will explode violently, transform into energy and annihilate. But at present, all the celestial bodies in the universe are positive matter, no antimatter celestial bodies have been found, and no violent explosion when positive and negative matter meet has been observed. Therefore, the basic research done by this laboratory is very valuable for understanding the secret of the origin of the universe.

5. Yunnan Germplasm Resources.

There are more than 6000 species of higher plants/kloc-0 in Yunnan province, accounting for about 50% of the whole country. Vertebrate 1704 species, accounting for about 55% of the country; Insect 100500 species, accounting for about 67% of the country. The establishment of Yunnan wildlife germplasm resources bank is an important scientific infrastructure for implementing the strategy of biodiversity protection and sustainable development, and it is also an important national interest. This will be of great scientific significance to the development of China's biotechnology industry, the future international resource competition and the security of national germplasm resources.

In March, 2004, the National Development and Reform Commission agreed to build the China Southwest Wildlife Germplasm Resource Bank, and included the project in the national major scientific engineering construction plan, with a total investment of 654.38+0.48 billion yuan, which passed the national acceptance in 2009.

The museum has built a conservation facility of wildlife germplasm resources with important international influence, and its conservation capacity has reached the international leading level, which is irreplaceable. It has become one of the two wildlife germplasm resources preservation facilities established according to international standards in the world. At present, the bank has collected and preserved about 4,000 species and 20,000 wild plant seed banks, and officially backed up and preserved the seeds from the Millennium Seed Bank of the Royal Botanical Garden and the World Agroforestry Center (ICRAF).

In addition, China is planning to build the world's largest particle collider. According to American media reports, with the support of international partners, scientists from the Institute of High Energy Physics of the Chinese Academy of Sciences are planning to build a Higgs particle factory by 2028. This will be a 52-kilometer-long underground loop, which can make electrons and electrons collide. The collision of these elementary particles will enable people to study the Higgs boson with higher accuracy. The accuracy of the collider will be higher than that of the smaller Large Hadron Collider at CERN. Once completed, China will break the monopoly of the United States and Europe in this field.

It can be predicted that there will be more large-scale basic scientific research projects in China in the future, and the economy will develop. China is accelerating to catch up with the West in the field of basic science.
