摘　　要：以球形或椭球形颗粒介质为例,从颗粒介质内外电势分布出发,得出了颗粒介质内部退极化场,从而进一步讨论了退极化因子和形状因子的关系.Based on the spatial distribution of electric potential of a sphere or ellipsoid in a matrix, the depolarizing field inside the sphere or ellipsoid is investigated. Furthermore,the relation between depolarizing factor and shape factor is obtained.
