| 摘 要： | 以相互作用能为基础阐明静电场中自能与相互作用能之间的联系和区别，总结出带电系统自能和相互作用能的计算方法，并从理论上证明带电体系统的自能永远大于零，而相互作用能却可以为正、为负、为零.

| Abstract: | Correlations and differences between self-potential energy(PES)and interactive potential energy (PEI)of static electric fields were discussed. A summary was given to methods of calculating PES and PEI of charged systems. It was proved that in a charged system,PEs is always greater than zero,but PEI can be positive,negative or zero. |
