摘　　要：本文对谐振电偶极子辐射场公式进行拓展,采用叠加原理,得出了匀速转动电偶极子的电磁场表达式。同时,基于Matlab数值计算软件,将抽象化的电磁场表达式通过动态形式展现出来,使得对于旋转电偶极子的电磁场传播特性能够得到更加直观的认知,为电偶极子辐射的研究和教学提供一种新方法。In this paper, the radiation field formula of the resonant electric dipole is extended, and a formula of electromagnetic radiation field of the electric dipole with uniform rotation is obtained by using the principle of superposition. Based on the numerical calculation software of Matlab, the abstract equations of electromagnetic field are displayed in animate forms. So the propagation feature of electromagnetic field radiated by the rotating electric dipole can be more intuitively recognized, which provides an alternative approach for the research and teaching of electric dipole radiation.
