I browse news sites as usual, the news of the 2022 Nobel Prize in Physics attracted me, we congratulate Alain Aspect, John F. Clauser and Anton Zeilinger Won the Nobel Prize in Physics, their main contribution lies in the experimental research work in quantum optics and atomic physics, especially the pioneering work in verifying Bell's inequality.
As Armstrong said when he landed on the moon in 1969, "That's one small step for mankind, one giant leap for mankind", we admire the pioneers explore the world and paint a better future for mankind，with their efforts,our world is a better place,beautiful and harmonious. However, the birth of these physics and astronomy is their collision of ideas in the laboratory, reasoning of data, and experiments; As an old Chinese saying goes, if a worker wants to do a good job, he must first sharpen his tools. These laboratories and scientific instruments are beneficial to their research, and diesel generator sets are used as emergency or prime power sources to provide power for these laboratories and experimental equipment.
In 2020, the 500-meter-aperture spherical radio telescope in China was officially put into operation and opened to the global scientific community. In mid-2022, an international team led by Li Di, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences, passed the "Multi-Science Target Simultaneous Survey (CRAFTS) of China Sky Eye FAST. )” priority major project, and found the only case of persistently active repeating fast radio storm FRB 20190520B so far. After that, the team organized multiple international equipment to observe the sky and the earth, and integrated data from radio interference arrays, optical, infrared telescopes, and space high-energy observatories to locate FRB 20190520B in a metal-poor dwarf galaxy 3 billion light-years away from us. The source region has the largest electron density known so far, and the second FRB persistent radio source counterpart (Persistent Radio Source, PRS) has been discovered so far. The above findings reveal that the complex environment around active repeating bursts has characteristics similar to super-bright supernova explosions, challenging the traditional view of FRB dispersion analysis, and laying the foundation for building the evolution model of FRBs and understanding this violent cosmic mysterious phenomenon . The result was published in the international academic journal Nature on June 9, 2022, Beijing time. This time, the emergency power guarantee for FAST is the land use diesel generator. It has the advantages of low fuel consumption, high power, high product stability, good emission performance, good environmental applicability, and convenient use and maintenance.
