摘　　要：本文分析了引起并影响固体电解质材料晶界电行为的因素及研究多晶固体电解质材料晶界效应的各种模型,重点讨论了"砖块模型"(brick-layer model)及其适用范围。Grain-boundary effect is an important topic in the study of the electrical properties of solid electrolytes. This paper presented a brief review on this issue. The factors that arouse and influence the grain-boundary blocking behavior were analyzed and some existing models, especially the widely-adopted ＂brick layer model＂, for describing the gain-boundary effect were discussed.

关 键 词：晶界效应 固体电解质 溶质偏析 砖块模型
