摘要
本文根据任意介质中电磁场的Ｍａｘｗｅｌｌ方程解，求出了薄园盘介质在Ｐ不断改变情况下在远处所产生的电磁场．这种典型的计算方法，对于解决实际问题具有指导意义．
In this paper, we shall use solutions of Maxwell equations for electric and magnetic fieds in arbitrary media, Let us find the time-variable electric and magnetic fields thin P of the disk-shaped electric meson suddenly changes at a large distance r >>a>>d from it. This example involves a variety of typical computations, it is much more meaningful and universal.
