静电场中极化介质的能量及能量密度
摘要
本文给出了在场源不变和电势不变的条件下
静电场中移入有限体积的介质后电场能量的变化
并且推出极化介质的能量表达式
同时指出这两种条件下表达式不同的物理意义.
Abstract
The energy variance of a static electric field when a dielectric of finite volume is presented under conditions of constant field source or boundary potential unchanged is discussed. The expressions of the polarization energy of the dielectric in both conditions is deduced and the difference of the physical meaning of this two expressions is pointed out.
