By making use of the element properties of α-diagonally dominant matrix and adding the appropriate parameters,we present a set of determination conditions for nonsingular H-matrix and verify the effectiveness of the method  by numerical examples.

Key words: nonsingula H-matrix, &alpha, -diagonally dominant matrix, inequality, determination
