摘要
提供一种与能带计算相容的相稳定性判定方法，通过对过渡合金Ａ１５相的计算，所得结果与能带计算十分接近，证明该法的有效性。同时还根据判定结果推测了Ａ１５超导现象的机制，为高ＴＣ提供了新的理论证据。
The aim of this paper is to present a new method in determinating the phase stability of alloys in relating to the Energy Band Calculations. Through the calculations of A15 alloys, the results are quite equivalent to those given by the Energy Band Calculations. This proves the effectiveness of the method. At the same time, the results are made to discuss the mechanism of superconductivity,and a new criterion of high Tc is also given.
