摘　　要：给出两个矩阵范畴MZ和MZ[i]中态射满单分解的等价条件,并利用该等价条件讨论了这两个范畴中态射Moore-Penrose逆之间的关系.This paper gives the equivalent conditions of the epic-monic factorization of related morphisms in matrix category in Gauss integral domain and integral domain, and then studies the relationship between Moore-Penrose inverses of related morphisms of the two categories with the equivalent conditions.

关 键 词：满态射 单态射 满单分解 MOORE-PENROSE逆
