1987年,赵忠贤及合作者发现液氮温区高温超导体,并在国际上首次公布其元素组成为钇钡铜氧。国际上很多实验室验证了中国的工作,掀起国际高温超导研究热潮。赵忠贤因此于1987年获得第三世界科学院物理奖,这是中国科学家首次获此奖项。1989年,其因“液氮温区氧化物超导电性的发现”获国家自然科学集体一等奖。2014年初,时隔20余年,赵 In 1987, Zhao Zhongxian and his collaborators discovered the high-temperature superconductor liquid nitrogen temperature zone, and the first time in the world announced its elemental composition of yttrium barium copper oxygen. Many laboratories in the world have verified the work of China and set off an upsurge of international HTS research. Zhao Zhongxian therefore won the Third World Academy of Sciences Physics Prize in 1987, which is the first time that Chinese scientists have won this award. In 1989, due to “liquid nitrogen temperature oxide superconductivity found ” won the first prize of the National Natural Science collective. In early 2014, after more than 20 years, Zhao
