摘　　要：本文对液氮温区的大块体超导材料的约瑟夫逊效应进行了实验研究.我们证实在未加工成任何弱连接形式的体超导材料上也会观察到约瑟夫逊效应.这对于搞清液氮温区超导材料的特性及其应用都具有一定的参考价值.Experimental studies were made in Josephson effect of bulk superconductive materials at liquid nitrogen temperature. Our studies have come to prove that Josephson effect can surely be observed in the bulk superconductive materials without being manufactured in any kind of weak links. The results of our studies are significant for probing the characteristics of superconductive materials at liquid nitrogen temperature and for the applications of these materials.
