摘要：

Taking the two-local-spin-mediated interaction (TLSMI) as the pair potential for the Cooper pair and considering the long-range phase coherence (LRPC), the empirical formula of T-c versus hole doping is explained and the physical picture for the pseudogap and the gap in superconductive state is set up. The superconductivity in PrBa2Cu3O7-delta and CuCl at high pressure and Fe1-xS is discussed.
