无限大带电体之间的静电势能的计算

Calculation of the Electrostatic Potential Energy Between TwoInfinite Charged Bodies

通过求解静电场的泊松方程以及静电场基本概念的运用 ,给出无限大带电体之间的静电势能的两种简便计算方法 ,与教程常用方法相比更易于掌握 .对掌握量子力学中利用微扰法和变分法计算氦原子基态能量、以及掌握电磁学中静电势能的计算等问题有很好的帮助 .

Two simple methods for calculating the electrostatic potential energy between two infinite charged bodies are introduced,using Poisson equation and the basic concepts on electrostatic field respectively.These two methods are easier to master than the usual one.It helps to get a good understanding of the problems such as the calculation of helium atom ground state energy using the perturbation theory or variational method in quantum mechanics,the calculation of the electrostatic potential energy in magnetoelectricity,etc.
