摘      要：I. INTRODUCTIONTc of the oxide Bi-Sr-Cu-O system without lanthanide is 20 K. Doping Ca in proper amount will make it show 85 K superconductivity accompanied by 110 K superconducting trace. Y. Koike et al. have obtained Bi2Sr2CaCu2Oy single crystal and measured its fundamental superconductivity parameters. Endo et al. have prepared single-phase 110 K Bi-
