Several new criteria are obtained for nonsingular H-matrices according to the properties of nonsingular matrices and through constructing the coefficient and selecting the positive diagonal factor.The effectiveness of the results is verified by a numerical example.

Key words: nonsingular H-matrix, irreducibility, nonzero elements chain, criteria
