本文给出电子多声子作用对电子寿命影响的一般讨论方法,同时给出温度T》德拜温度TD的表达式,指出YBaCuO体系中电子多声子作用对高温超导性可能是重要的。A general approach for analysing the effect of electron-many phonon interaction on electron life time and the corresponding expressions are present for the case of temperature T》 Debye Temperatule TD. It is pointed out that the electron-many phonon interaction may be important for 90 K superconductivyty in Y1Ba2Cu3O7-δ.
