Abstract: Block H-matrices play an important role for convergence of block iterative methods of the system of linear equations.In  this paper,on the basis of determining point H-matrices,the authors get some sufficient conditions for nonsingular H-matrices by applying block matrix technology,improving and extending some of the recent corresponding results.

Key words: block H-matrix, diagonal dominance, block diagonal dominance, sufficient condition
