摘　　要：利用共轭次转置阵和可逆Hermite矩阵给出了拟次酉阵的概念,从而拓广了酉矩阵和拟酉矩阵的概念,并研究了拟次酉阵的若干基本性质及其特征值和特征向量.Using conjugate sub-transposed matrices and reversible Hermite matrices, the concept of quasi-sub-unitary matrix was given. Moreover, the concepts of unitary matrices and quasi-unitary matrices were extended. Finally, some basic properties, eigenvalues and eigenvectors of the quasi-sub-unitary matrix were discussed.

关 键 词：共轭次转置阵 可逆Hermite阵 拟次酉阵
