摘　　要：本文研究了X-扩张模.利用A( X,M)-c-内射模的概念,获得了A( X,M)-c-内射模的有限直和仍是A( X,M)-c-内射模的一个充分必要条件,并推广了相应的结果.In this paper we study X-extending module by the concept of A（X,M）-c-injective modules. A necessary and sufficient condition that the finite direct sum of A（X, M）-c-injective modules is also A（X,M）-c-injective is given. Some known results in this direction are extended.

关 键 词：A(X M)-c-内射模 基本A(X M)-c-内射模 X-extending模
