摘　　要：介绍超导腔热击穿原理 ;讨论了超导体热击穿磁场与超导材料 RRR值之间的定量关系 ;同时介绍一种非常实用的超导腔体 RRR值的测量方法涡流法无损测量原理及其实现方法 ;最后给出了国内外两种典型超导铌材料In this paper, the thermal break down of superconducting cavity is introduced and the relation between the possible maximum magnetic field and RRR value is discussed. A kind of nondestructive RRR detection technique-Eddy Current method and its experimental setup are also introduced. Finally, some results of RRR test for two kinds of Niobium materials are presented.
