| 摘 要： | 直内射的概念是(拟)内射的推广,它是由W.K.Nicholson于1976年首先引进的。本文研究直内射模的性质,并且给出一个R-模是直内射模的充分必要条件。

| Abstract: | The concept of direct injectivity as a generalization of (quasi) injectivity was introduced by W. K. Nicholson in 1976. In this paper we investigate properties of direct injective modules, and attempt to obtain a necessary and sufficient condition for a R-module to be direct injective. |
