摘　　要：从理论上证明了传统矢量积分法(包括位函数法)和并矢格林函数法在解决电磁场问题时所得积分解是等效的,并以求解电基本振子辐射电磁场为例,通过比较分析发现,用并矢格林函数法能够避免许多复杂运算,使求解过程方便、简捷,因此该方法在电磁场求解中具有广泛的理论和实际应用价值.Theoretically, this paper proves that the traditional vector integral method(including potential function method) and dyadic Green’s function method, when solving the electromagnetic field problems, their integrated solutions are equivalent. It takes the solution of electromagnetic field radiated by electric short dipole as an example and proves that, by comparative analysis, using dyadic Green’s function method can avoid or simplify many complex operations and the solution process becomes convenient and simple.Therefore, this method has wide application value in the electromagnetic field solution.
