China’s major scientific and technological achievements
In 2021, a number of major scientific and technological innovation achievements in China were unveiled one after another: the birth of the world’s first cloned monkey, the completion of the deepest scientific drilling well in Asia, the “artificial sun” reaching 100 million degrees for the first time… These achievements reflect China’s great strides in the field of science and technology Progress.
1. The world’s first somatic cell cloned monkey was born in China
On January 24, the Chinese Academy of Sciences announced that the world’s first somatic cloned monkey “Zhongzhong” was born on November 27, 2017, and on December 5, the second cloned monkey “Hua Hua” was born. The international authoritative academic journal “Cell” published the results online as a cover article.
2. China’s first electromagnetic detection test satellite was successfully launched
On February 2, China’s electromagnetic detection test satellite “Zhangheng-1” was launched at the Jiuquan Satellite Launch Center. This marks China as one of the few countries in the world with high-precision geophysical field detection satellites in orbit.
3. The deepest scientific drilling well in Asia is completed
On May 26, the Songliao Basin Continental Deep Scientific Drilling Project, the Songke No. 2 Well, exceeded its target and successfully completed the well. The final drilling depth was 7,018 meters, making it the deepest continental scientific drilling implemented by Asian countries and the deepest drilling implemented by the International Scientific Drilling Program (ICDP) in the 22 years since the establishment of the International Scientific Drilling Program (ICDP).
4. The first trial voyage of the heavy dredging device “Tian Kun” was successful
On June 12, the first self-propelled cutter suction dredger in Asia, Tiankun, which was independently designed and built by China, completed its first trial voyage. The “Tiankun” is 140 meters long, 27.8 meters wide, and has a maximum excavation depth of 35 meters. meters, the total installed power is 25,843 kilowatts, the designed dredging is 6,000 cubic meters per hour, and the rated power of the reamer is 6,600 kilowatts.
5. Yuan Longping’s team successfully tested “Desert Sea Rice”
On July 22, the Qingdao Sea Rice R&D Center announced that more than 80 varieties of rice, including “sea rice”, which were tested by the “sea rice” team of Academician Yuan Longping, matured in batches, and the output exceeded the world average of 4.539 tons per hectare of rice. Yield. This marks the staged success of Yuan Longping’s “sea rice” team’s trial planting in the Dubai desert.
Sixth, the domestic large-scale amphibious aircraft successfully made its first flight on water
On October 20, the domestic large-scale waterway amphibious aircraft “Kunlong AG600” successfully took off and landed for the first time on water at Zhanghe Airport in Jingmen, Hubei. It is another important breakthrough made by China in the field of large aircraft, filling the gap in China’s development of amphibious aircraft.
7. The “lung” of the fourth generation nuclear power passed the acceptance
On October 31, the world’s first pebble bed modular high-temperature gas-cooled reactor steam generator successfully passed the acceptance inspection. The steam generator is one of the most critical equipment in the high-temperature gas-cooled reactor nuclear power system, which is called “the lung of nuclear power” in the industry.
8. China’s “artificial sun” achieves 100 million degrees operation for the first time
On November 12, the Institute of Plasma of the Chinese Academy of Sciences released news that the fully superconducting tokamak nuclear fusion scientific device (EAST), known as the “artificial sun”, has achieved many major breakthroughs such as 100 million degrees Celsius plasma operation.
9. The Change-4 probe of the lunar exploration project was successfully launched
On December 8, China successfully launched the Change-4 probe at the Xichang Satellite Launch Center with the Long March 3B carrier rocket, opening a new journey of lunar exploration. Subsequent experience of earth-moon transfer, near-moon braking, and circum-moon flight, finally achieved the first human soft landing on the far side of the moon.
10. Beidou-3 began to provide global services
On December 27, Ran Chengqi, director of the China Satellite Navigation System Management Office and spokesman for the Beidou satellite navigation system, announced at a press conference of the State Council Information Office that the basic system of Beidou-3 had been completed and began to provide global services on the same day. This marks the expansion of the service scope of the Beidou system from regional to global, and the Beidou system has officially entered the global era.
