| 摘 要： | 本文在BCS理论的基础上考虑了电子-原子实的作用对T_c的影响,这个影响相当于电子之间的一个关联作用,由此利用Gorkov的电子对格林函数方法得到T_c公式。用这个模型对最近的高温超导能作一些解释。

| Abstract: | In this paper , the effect of electon-atomic core interaction on Tc of superconductor is considered besides the effect of electron-phonon interaction in BCS theory. It is assumed that such interaction between electron and atomic core can lead to an effective attraction between electrons, A new Tc function is obtained by means of Gorkov's Green function of electron pair. It is shown that our model can give some explanation of high Tc superconductivity. |
