摘　　要：介绍一种计算感生电场的数值方法,它既可用于计算柱形分布均匀变化磁场所产生的感生电场,也可计算分布在任意界面上的变化磁场所产生的感生电场,并给出了一些计算实例.A simple numerical method to calculate the induced electric field is presented at the level of the college physics.One can obtain not only the distribution of the induced electric field produced by the uniform variable magnetic field in the cylindrical space, but also the distribution produced by the variation of the magnetic field with arbitrary formal interface. Some examples are also given.
