| 摘 要： | 实验得知0.5Li_2S-0.5GeS_2玻璃的电导率高于0.4Li_2S-0.6GeS_2玻璃的电导率。当在这两种组成的玻璃中分别掺杂 LiI 后,则后者的电导率可高于前者。在0.4Li_2S-0.6GeS_2玻璃中同时掺杂LiBr 和 LiI 后,其电导率约为掺杂一种同量盐玻璃电导率的两倍。本文用弱电解质理论解释了Li_2S-GeS_2玻璃经掺杂 LiBr 和 LiI 后电导率变化的原因。

| Abstract: | The electric conductivity of 0.5Li_2S-0.5GeS_2 glass is higher than0.4Li_2S-0.6GeS_2 glass.But the electric conductivity of latter has higher value than theformer when these two glasses mix LiI respectively.If two kinds of additive salt LiI andLiBr are add to the glass of 0.4Li_2S-0.6GeS_2 the electric conductirity of this doping glass isabout one time higher than adding the same quantity of only one.This change in electricconductivity caused by adding LiI and LiBr to Li_2S-GeS_2 base galss can be understood inweak dielectric theory. |
