叠加原理在分离变量法解静电问题中的灵活应用

Agile Application of the Principle of Superpoiction in Solving the Electrostatic Prottem bey Using the separation of Variatles

本文阐述了势叠加原理结合分离变量法求解静电问题时，无电荷区分离变量势选取的非唯一性。

In this papre, we elaborate the non-uniqueness of selecting electing electric potential in non-electric charge region to solve electrostatic problem by using the principle of superposition and the separation of variables,and explain it with an example.
