摘要
本文研究本征方程［Ａ］［ｕ］＝λ［ｕ］的矩阵摄动理论，进而给出了本征值λ和本征矢［ｕ］的１－３阶摄动解，并应用于微波谐振腔的具体实例。
The matrix perturbation theory to eigen equation [A][u]=λ[u]is investigated, in which 1-3 order perturbation solutions to eigen value λ and eigen vector[u]are further given.One of the applications of above theory-microwave resonant cavity is researched.
