摘　　要：在次对称矩阵定义的基础上给出了K-(反)次对称矩阵的概念,利用次对称矩阵的研究方法及特殊矩阵K的性质,推出了K-(反)次对称矩阵的若干性质,研究了几个与K-(反)次对称矩阵相关的问题,并讨论了K-次对称矩阵和K-次正交矩阵之间的关系,得出了一些新的结果.The concept of the K-（anti）sub-symmetric matrix is derived from the definition of sub-symmetric matrix.Some properties about K-（anti）sub-symmetric matrix are discussed on the basis of the research methods of sub-symmetric matrix and the properties of special matrix K.Some K-（anti）sub-symmetric related issues are investigated and the relations between K-（anti）sub-symmetric matrix and K-（anti）sub-orthogonal matrix are discussed.Some new results are obtained.
