摘要
以更简洁的方法导出用电势和电荷密度表示的静电相互作用能的普适公式。该公式通常含有1/2系数因子,它的特点是不涉及极化强度等不易获得的量,使用更为方便。利用该公式对含极化电荷场的能量进行了分析,得出自由电荷场与极化电荷场间的相互作用能具有1/2系数因子的结论,从而更正了"在任意情况下相互作用能都没有1/2系数因子"的错误认识。
The general formula is one whose characteristics is not related to such quantity as polarized intensity often has with a 1/2coefficient gene of interactional energy in the static field with electricity force and electricity density in a more compact and convenience way. A conclusion of 1/2 coefficient gene is in the formula of interactional energy between free electricity field and polarized electricity field which is drawn from analyzing the energy in the polarized electricity field thus correcting the wrong cognition that there is no such gene in any condition.
