摘　　要：BCS超导电性微观理论中提出超导材料的超导转变温度Tc由θ(临近费米界面电子之间的相互吸引),λeff=N(O)V(N(O)在费米界面每单位能量的一种自旋Bloch态密度;V=<Vkk′>平均,电子对在-ω<ε<ω在区域中跃迁的矩阵元Vkk′能为衡量的平均矩阵元)决定,并给出计算公式.基于高Tc超导材料的特征,用电负性均衡原理分析了由于在高Tc超导材料中的元素有化学键的形成,N(O)和V具有特殊的变化,电声子机制可以产生高Tc超导电性。On the basis of the characteristics of the highTcsuperconductors,the principle of the electro-negativity equalization was used to analyze and study the formation of chemical bonds of the elements in the highTcsuperconductors and the Tccomputing formula in the theory of BCS,Tc=θDeλe1ffwhereλeff=N（O）V,（N（O）is a kind of the density of the Bloch state in each unit energy on the Fermi face;V=Vkk＇averagewhile the transition matrixVkk＇of the electronic pairs in the range of -ωεωis the average matrix element of constant energy）,both of them are of special change.Thus a conclusion is made that the mechanism electrons media possible formation the highTcsupercomputer.
