摘　　要：首先介绍基于积分方程的矩量法原理及其特点。基于传统矩量法在解决电大尺寸电磁场问题上的局限性,分析几种典型的改进矩量法,包括快速多极子方法、小波矩量法、混合算法和自适应积分法。几种方法通过不同的途径减小了计算量,所以将几种方法结合起来使用,可以有效地解决电大尺寸电磁场问题。运用改进的矩量法,突破了传统矩量法解决电大尺寸电磁场问题的局限性。The principle and characters of MoM based on integral equation are introduced. Several non - traditional MoM including FMM, wavelet - MoM, hybrid technique and AIM are analyzed based on the limitation of traditional MoM on solving problem of electrically large problem. Thus different method can reduce eomputational effort through different way, so the large electromagnetic problem can be solved effectively through association of several methods. The limitation traditional MoM on solving problem of electrically large problem is broke through using non - traditional MoM.
