低温超导材料研究进展

Research Progress on Cryogenic Superconducting

超导体由于具有零电阻效应、迈斯纳效应和约瑟夫森效应,使得超导技术在现代化工业建设中起着至关重要的作用。超导体可分为高温和低温两类,而低温超导材料具有更广泛的应用。简单介绍了低温超导体的性质,综述了低温超导磁体、Nb基和其他低温超导材料的性能及应用,提出了低温超导技术中所用材料及在焊接技术上存在的问题,并展望了其发展方向。

Having the zero resistance,meissnerts effect and Josephson effect of the superconductors,superconducting technology plays an important role in the modern industry.Superconductors contain high temperature superconductors and cryogenic superconductors,but the latter has more widely usage.The properties of cryogenic superconductors were simply introduced,the performance and application of cryogenic superconducting magnet,Nb based cryogenic superconducting materials and other cryogenic superconducting materials were reviewed,the prQblems of the using materials in cryogenic superconducting technology and the welding technology were projected,and the development was prospected.
