| 摘 要： | 本文引入了（e，M）-内射模的概念．设M是任意一个固定的右R-模．移右R-模X是（e，M）-内射模，如果对任意的基本单同态f：K→M，从K到X的任意同态都能扩张到M．本文给出了（e，M）-内射模的一些性质和刻画．

| Abstract: | Let M be an arbitrary but fixed right Rmodule. A right Rmodule X is called （e,M）-injective in case for any essential monomorphism K→M, every right Rhomomorphism from K to X extends to M. Some properties and characterizations of （e,M）injective modules are given in this paper. |
