摘　　要：给出广义电磁场矢量和并矢波动方程的格林函数积分解,在物理定律和边界条件的约束下,用并矢分析的方法证明了两解的同解性,并对自由空间并矢格林函数的对称性进行了并矢分析展开验证。结合并矢分析法求解电磁场的两个应用实例,表明并矢分析法相对于传统方法具有简捷明了的特性。This paper gives the two Green＇s function integral solutions of the electromagnetic general Maxwell vector and dyadic wave equations. The equality between the two solutions has been demonstrated applying the dyadic analysis method on condition of obeying the electromagnetic physical principals and boundary conditions. It verifies the symmetry of the dyadic Green＇s function of the free space by expanding the function using the dyadic analysis. Two applications of solving the electromagnetic fields using the dyadic analysis method show that the dyadic analysis method in solving the electromagnetic fields is simpler and quicker than the traditional analysis methods.
