| 摘 要： | 利用麦克斯韦方程组和场的轴对称性,分别对含不稳定电荷源和不稳定电流源的轴对称非静态空间电磁场进行了研究.首先,导出了3个基本表达式,然后,以对称轴的已知不稳定场量作为初始值,通过不断迭代并总结其规律,给出由对称轴上的已知不稳定场量来表示轴外任意一点电磁场的无穷级数表达式,最后,对结果进行了验证,对其敛散性进行了分析.

| Abstract: | By using the Maxwell's equations and axial symmetry,the axial symmetric unstable electromagnetic field with unstable charge source and unstable current source is studied.First,three elementary expressions are derived,then,the infinite series expression of electromagnetic field is obtained by using the known field expression in axial.At last,the convergence results is varified. |
