从对ZnO和SrTiO3的晶体结构参数的计算出发，论述了铜和碱金属原子在这两种晶体中所处的位置。实验结果证实，同一种原子在不同的材料中可以起不同的作用。文章还讨论了这些杂质对压敏陶瓷的压敏电压、电容量、有效相对介电系数影响的机理。

According to the crystal structures of ZnO and SrTiO3，the positions of copper atoms and alkali metal atoms in the ceramic materials are discussed．It is shown as experiment result that the same atoms could have different roles in different crystal structures．The mechanism that copper atoms and alkali metal atoms have effects on breakdown voltage，capacitance and effective relative pemrmittivity of varistor ceramics are researched in the paper．
