摘　　要：指出了已有文献中非奇异H矩阵判定定理的某些条件是平凡的,并且进一步给出了新的非奇异H矩阵的简捷而实用的充分性判别准则。This paper shows that those thermore, it obtains several practical exampleto illustrate the advantages of sufficient conditions for nonsingular H - matrices in literature are trivial. Fursufficient conditions for nonsingular H - matrices. Finally it gives a numerical presented results.
