On Properties of the k-Row Orthogonal Matrix

The concepts of orthogonal matrix and symmetric matrices have been given,center symmetry of the k-row orthogonal matrix discussed before the following conclusions are drawn: k-row orthogonal matrix is a centrosymmetric matrix;k-row orthogonal matrix transposes matrix transpose rows and columns transposed matrix and its inverse matrix and the adjoint matrix are centrosymmetric matrix;orthogonal matrix of several k-rows is still the center symmetric matrix.
