摘要
指出与象电荷有关的系统的互能、互作用力和真实电荷系统的互能、互作用力分别相等，自能。
It is pointed out that the interaction energy and interaction force of a charge system involving image charges equals those of a real charge system respectively and the self energy and total energy of a charge system involving image charges not equals those of a real charge system.
