摘　　要：给出了k-广义酉矩阵的概念,研究了它的性质及其与酉阵、辛阵、Householder阵、Hermite阵、Hamilton阵及广义逆矩阵之间的联系,从而推广了酉矩阵、Hermite阵、斜Hermite阵及Householder阵的相应结果,并将正交阵的广义Cayley分解推广到了广义酉矩阵.　The concepts of k-generalized unitary matrix are given,its properties and relations between they and unitary matrix,symplectic matrix,Householder matrix,Hermite matrix,Hamilton matrix and generalized inverse matrix are studied.Moreover,the corresponding results on relations among unitary matrix,Hermite matrix,anti-Hermite matrix and Householder matrix are popularized,especially the Cayley decomposition of orthogonal matrix is extended to generalized unitary matrix.

关 键 词：k-广义酉矩阵 酉矩阵 广义Hermite阵 广义逆矩阵 辛矩阵
