负U中心模型的超导转变温度及同位素效应

Superconducting Transition Temperature and Isotopic Effect of a Negative U Center MOdel

针对高温氧化物超导体，根据有关理论及实验研究结果，给出一个简单的负Ｕ中心模型，研究了超导转变温度及同位素效应，并得到与实验相符的结论。

A sim ple negative U center medel,whiCh is in connection with high Tc oxide supercoductiors,has been given on the basis of the theoritical and experimental results.The transition temperature and the isotopic effect have been investigated.The results are consistent with the experiments.
