摘　　要：带电系统的静电势能是在系统的形成过程中,外力克服电场力做功转换而来的,其总静电能应等于诸电荷元的自能和电荷元之间的互能之和,在电场中没有电荷的地方也有能量,亦即能量定域于电场之中。The electrostatic potential energy of electrification system is formed in the system formation and is changed from the work done in the process of the outer force conquering the force of electric field. The total electrostatic energy is equal to the sum of self-energy of the charge origins plus the mutual energy between the charge origins. The energy exists even though there is no charge in the electric field. That is, energy is localized in the electric field.
