As the last piece of reflective surface unit complete hoisting, the preparation for 22 years of 500 - meter aperture spherical radio telescope (English abbreviation: FAST) the end of the principal part of the project. After put into operation, it will become the major science and technology infrastructure of cas a 17 members of the family.
For big science device, built is just the beginning, the use of good is the key. This is located in guizhou, the world's largest radio telescope can be used to listen to the radio waves from deep space, explore the universe change, extraterrestrial nova and living organisms. FAST was known as the "third eye", is expected to assist scientists in China hit a Nobel Prize. At present, there are 10 Nobel is based on astronomical observation results, among them, there are 6 items from radio telescopes.
As one over seventeen, behind the FAST refraction is the trend of China's scientific research unit "bigness", and China struggling to pursue science and technology infrastructure level determination. Unlike a slowing economy, scientific research is the center of the China in the future planning. Spending on research and development at present, China is now more than 2% of GDP, higher than the European Union, and is expected to reach 2.5% by 2020, overtaking the United States.
Done through large-scale investment and construction, is completed through the long-term stable operation and continuous science and technology activities, achieve important science and technology of large facilities.
Completed China's first big science device can be traced back to October 16, 1988, Beijing electron-positron collider (BEPC) for the first time the electron-positron collider. It with atomic bombs, hydrogen bombs, satellites, was the world's only in the tau lepton and charmed particle near the threshold study tau - large electron-positron collider charm physics experiment device, by far the highest brightness can also is the area of the collider.
China's use of Beijing electron-positron collider, usable value to describe. Since its completion, China has made a number of major achievements in the 90 s, as one of the high-energy physics research center of the world. At the same time, it also implements "dual-use" in one, is China's large-scale public synchrotron radiation experimental platform. In addition, the large electron-positron collider upgrade, also promoted the strength of China's manufacturing enterprises and collaborative research ability.
Currently, distributed in 10 provinces, there are 23 is running or under construction of the country's big science equipment, seven have approved facilities, involving the time standard distribution, remote sensing, particle physics and nuclear physics, astronomy, synchrotron radiation, geology, Marine, ecological and biological resources, energy and national security, and many other fields. The facilities of the application object is different, one kind is on a particular subject in the field of major goals of science and technology of construction, such as Beijing electron-positron collider, lanzhou heavy ion research unit, etc.; One kind is multiple disciplines in the field of basic research and applied basic research and applied research services, public experimental facilities, with strong support ability such as Shanghai light source, hefei synchrotron radiation devices, etc.; Another kind is for the national economic construction, national security and social development to provide basic data of public welfare facilities of science and technology, such as China's remote sensing satellite ground station, long short wave system, etc.
These big science device is one of the win technology say credentials in China. Large area area multi-object fiber spectroscopic telescope (also called guo shoujin astronomical telescope, English abbreviation: the LAMOST) with 4000 root optical fibers, with large diameter (4 meters) long and large field of view (5 c), spectrum to get the highest rate in the world of the glasses. According to the Chinese academy of sciences, major infrastructure sharing service platform of science and technology is introduced, since the official survey in September of 2012, three years, the LAMOST observation area 2669 days of external release 5.69 million spectral data, leads the world in all known spectral survey projects.
Big science unit as a research tool, the inspection standard is scientific research achievements transformation. As of November last year, the LAMOST has to help 84 SCI papers. Mass spectral data of the LAMOST astronomers were benefit, found a super-fast's nearest star it field velocity distribution of the new structure, the sun also precisely measure the sun's rate of this credit, the red giant surface gravity.
In march, at the national center for scientific protein (Shanghai), the researcher through the center of the protein frozen electron microscopy facilities, cracked the mechanism of the hand, foot and mouth disease virus antibody. This troubled millions of children diseases will probably developed the corresponding specific drug.
The BBC post commented: "China scientific research is showing rising ambition."
