摘　　要：各向同性线性电介质在外电场作用下极化,其极化与外场及介质本身的几何形状有关,本文从导出椭球形介质的退极化因子入手。As dielectric matter is polarzatied in the applied electric field, its polarzation depends on the applied electric field and the geometry of the dielectric matter. In this paper, starting from the deduction of the depolarzation factor of ellipsoid, we systematically explain physical meaning of the depolarzation factor.

关 键 词：退极化因子 极化强度 有效介电常数 电介质
