摘　　要：通过态射的正则性,讨论加法范畴中态射的广义Moore-Penrose逆.给出了正则态射的广义Moore-Penrose逆存在的几个充要条件以及广义Moore-Penrose逆的表达式.The generalized Moore-Penrose inverses of morphisms in an additive category with an involution are studied by regularity of morphisms. Some necessary and sufficient conditions for existence of the generalized Moore-Penrose inverses of regular morphisms and some expressions of the generalized Moore-Penrose inverses are given.
