由于高温超导氧化物在低于Ｔｃ的温度下热导低，因此，高温超导电流引线引起了人们的广泛注意．Ｖ．Ｐｌｅｃｈａｃｅｋ和Ｊ．Ｈｅｊｔａｍａｎｅｋ曾报道过冷等静压（ＣＩＰ）制造的Ｂｉ－２２２３管状电流引线，其临界电流密度（Ｊｃ）在７７Ｋ下为１０００Ａ／ｃｍ２．澳大?
Due to the low thermal conductivity of HTS at temperatures below Tc, high temperature superconducting current leads have drawn much attention. V. Plechacek and J. Hejtamanek reported a Bi-2223 tubular current lead made by cold isostatic pressing (CIP) with a critical current density (Jc) of 1000 A / cm2 at 77K. Australia?
