| Abstract: | In this paper,O-subcongruent of matices was introduced by the concepts of sub-congruent and O-congruent.The fact that O-subcongruent is a kind of equivalent relation was proved.Meanwhile,this paper also gave some necessary and sufficient conditions for O-subcongruent of matices.Then by the properties of sub-orthogonal matrix,the relations of their determinant were gained. |

| Keywords: | full-transposed sub-transposed O-subcongruent sub-orthogonal matrix |
