摘　　要：从０．７Ｂ：Ｏ３－０．３［ＸＮａ２Ｏ－（１－Ｘ）Ｌｉ２Ｏ］体系玻璃的电导率随摩尔分数Ｘ而变化，且在Ｘ＝０．５附近出现极小值这一实验事实出发，在考虑到所用溶液模型的同时，着重指出了带电体离子间的相互作用，从中导出了总电导率的数学表达式，因而更加圆满地解释了这种混合玻璃电导率下降的特殊现象。in consideration of the used solution model,and specially point out theinteractions between the charged ions,the relationship of the total conductivity of theglass 0. 7B,O3-0. 3[XNa2O-(1-X)Li2O]was derived from the experimental results thatthe conductivity depends on the mole portion X,and there is a minimal value at X=0. 5,so it was satisfactorily explained as a specific phenomenon that the conductivity of themixing glass decreases.
