摘　　要：针对玻璃导体中存在的“混合碱效应”，以０．５０Ｐ２Ｏ５－０．５０［ＸＮａ２Ｏ－（１－Ｘ）Ｌｉ２Ｏ］体系玻璃为例，根据弱电解质理论，通过一种假设溶液模型导出了具有一种形成体和两种改良体的三元混合玻璃的总电导率随两种改良体氧化物含量而变化的数学表达式．xperiments prove that 'Mixed Alkali Effect' exists in glass solids. In this paper 0. 50P2O5 -0. 50[XNa2O - (1 - X) Li2O] series is taken as an example. Based on a Weak solution theory', a solution model is supposed, in which a three-element mixed glass consists of one kind of formation element and two kinds of improved elements. The electric conductivity of this model glass varies with the quantity ratio of the two improved elements of oxides, and the mathematical expression is given.
