1987年,超导技术的研究出现了重大突破,美国、我国和日本先后制成了转变温度为98K左右的超导材料,人们已经获得液氮温区(77K)的超导体。同时,出现了世界上第一批超导技术的实际应用:美国研制出世界上第一个液氮温区超导器件——超导量子干涉器件、第一台液氮温区超导电动机、第一台采用超导芯片(约瑟夫森结)的超导高灵敏度示波器,日本研制出世界上第一条超导电磁推进船;苏联建成世界上功率最大的超导磁流体发电机;美国还正在投资建造世界上最大的加速器——超级超导质子反质子对撞机,将于1996年完
In 1987, there was a major breakthrough in the research of superconductivity. The United States, China and Japan successively produced superconducting materials with a transition temperature of about 98K. People have obtained superconductors in the liquid nitrogen temperature region (77K). At the same time, there was the practical application of the first batch of superconducting technologies in the world: the United States developed the world’s first liquid nitrogen temperature superconducting device - superconducting quantum interference device, the first liquid nitrogen superconducting motor, The first superconducting high sensitivity oscilloscope using superconducting chips (Josephson junction), Japan developed the world’s first superconducting electromagnetic propulsion ship; the Soviet Union built the world’s largest superconducting magnetic fluid power generator; the United States is still Investment in building the world’s largest accelerator - super superconducting proton anti proton collider, will be completed in 1996
