摘要
本文引进了具非零元素链二重几何平均对角占优矩阵的概念，讨论了它的性质及其与具非零元素链对角占优矩阵。
The concept of doubly geometric mean diagnally dominant matrices with nonzero elements chain are introduced, and the relations between the matrices and diagnally dominant matrices with nonzero elements chain as well as nonsingular H matrices are studied.
