【摘要】 分析了电子间在有效排斥互作用下的超导电性．发现当能带宽度Ｗ＞Ｅｃ，ｏ（）时，存在电子对；当Ｗ＜Ｅｃ，ｏ时，电子对消失．从而认为在电子对消失的区域，描写超导电性的应该是某种准粒子对，而不是电子对．更多还原

【Abstract】 The superconductivity in effective repulsive interaction between two electrons is considered. It is discovered that the electron pairs appear with energy band Width W>Ec,0 (Ec,0 = e); and they disappear with W<Ec,0 Therefore it is believed that superconductivity should be demonstrated with quasiparticle pairs in region where electron pairs disappear.更多还原
