| 摘 要： | 关于静电场中电势零点的选择,在原则上是可以任意选定的,而在某些情况下电势零点的选择要受到一定的限制。本文将从数学和物理的角度说明其选择的任意性,以及如何选择电势零点才既有物理意义又方便解题。最后讨论零点不同的电势如何进行叠加。

| Abstract: | Zero potential selection of electrostatic field can be randomly in principle,however,it's limited in some case.This article account for randomcity of the selection from mathematics and physics viewpoint and discusses about how to choose the electric potential zero point which seems to have much meaning of physics and to solve a problem conveniently.Eventually,it debates how to superpose the electric potential when the zero point is different. |

| Keywords: | static field electric potential reference point infinite point superpose |
