摘要
在引入区间α－二重几何平均对角占优矩阵概念的基础上，讨论了区间Ｈ－矩阵的判别条件，把黄廷祝（１９９４）的结果推广到区间矩阵的情形，得到了区间Ｈ－矩阵的几个充要条件和充分条件，从而推广和改进了黄廷祝，李有明等人相应的结果。
Abstract The interval α double geometric mean diagonally dominant matrices, the interval strictly α double geometric mean diagonally dominant matrices, the interval quasi α double geometric mean diagonally dominant matrices and the irreducible α double geometric mean diagonally dominant matrices are defined. Using these concepts, some equivalent conditions and sufficient conditions for interval A matrices are obtained. And some results in Ref are generalized and improved.
