摘　　要：求解了运动媒质中电磁势方程的格林函数，给出了无界空间的推迟势．结果表明，运动电磁媒质中的格林函数仍具有δ函数形式，场点对源点的时间响应特性不仅与媒质参量有关，而且与媒质运动速度有关．Solving the Green's functions of electromagnetic potential equations in moving medium,the retarded potentials in unlimited space are obtained. The results indicate that Green's function still is provided with δ-function form, and the time response of the field to source is not only related to medium parameter, but also related to moving velocity of the medium.
