摘　　要：一般情况下在感生(涡旋)电场中是不能引入电势和电势差的概念的,但当有导体参与时,自由电子在涡旋电场的作用下重新分布,出现了电荷的堆积,因而建立了静电场,从而可以比较电势的高低.接入常用的磁电型电压表对该电势差进行测量和计算,会发现不同的连接方式,测量和计算的结果不同;甚至会发现同时接入多个电压表时,各块表的测量和计算结果也不相同.The concepts of the electric field potential and the electric potential difference can not be introduced in the induced （vortex） electric field under normal circumstances, but when there is conductor, the free electrons in the vortex electric field redistribution and accumulation, which established the electrostatic field, and allowed us to compare the level of potential. The electrical potential difference was measured and calculated by using commonly magnetoelectric voltmeter,it was find that the measurement and calculation results are different for different connection methods, and even find the voltage measurements and calculation of tables is not the same for the voltage tables connected together.
