摘　　要：In this paper, we introduce the concept ofα-bidiagonally dominant matrices and obtain some criteria of generalized strictly diagonally dominant matrices. Thus the corresponding results of [1-4] are generalized.In this paper, we introduce the concept ofα-bidiagonally dominant matrices and obtain some criteria of generalized strictly diagonally dominant matrices.
