| 摘 要： | 本文系统地研究了YBa2-xSrxCu3O7-δ中超导电性与物相以及结构变化之间的关系。发现当0c并不随Sr的含量而单调变化。在x=1.0处,Tc出现一峰值。同时,超导临界温度与样品的晶体结构之间呈现出强烈的相关性:随着正交性的增强(即a,b间差值的增大),Tc单调地上升。本文还就S关键词：

| Abstract: | The relation between superconductivity and phase structure of YBa2-xSrxCu3O7-δ system has been studied systematically. It is found that when 0c increases monotonously. The mechanism of the effect of Sr atom on Tc and superconductivity have also been discussed. |
