There is a electric potential value according to every point in the electric field. The potential values of continuous charged bodies were computed. The computing results were shown through Mathematica software. The method of computing potential value was summarized.% 电场中任意点都具有一定的电势。计算了几种连续分布的带电体周围的电势，把结果用Mathematica软件加以演示，总结出了连续分布电荷电场中电势的计算方法，其结果一目了然。
