摘　　要：文中研究了一般范畴中态射 =1d2 的广义逆 ,若有态射′1,′2 满足′11d =d =d2 ′2 时 ,用d的M P逆给出了的广义逆存在的充要条件 ,同时得到了相应广义逆的表达式 ,推广了以往文献的有关结果 。The generalized inverse of the morphism product  1d 2 is studied. Suppose that  ′ 1 and  ′ 2 are satisfied:  ′ 1 1d= d= d 2 ′ 2 ,and then the necessary and sufficient conditions for the existence of the generalized inverse of  1d 2 are obtained by the Moore Penrose inverse of d, with the characterization of the generalized inverse given. The results and using random appering in references are extended.
