| 摘 要： | Since the discovery of high temperature supercon-ductivity by Bednorz et al. in 19861], many series of cu- prate superconductors have been synthesized. Critical temperature has been improved continuously. But no verdict has been given upon what mechanism causes su- perconductivity. CaCuO2 conductive layers are the parent structure of the high Tc cuprate superconductors, such as Cu-12 (n-1)n2], Tl-12(n-1)n3] and Hg-12(n-1)n4,5] super- conductor families. In 1988, infinite-layer (Ca0.86S…
