关于分次内射模的几点注记

Some Remarks on Graded Injective Module

分次内射模是分次模范畴三大模类之一，本文对分次内射模的性质作了一些研究，得到了它的一些等价刻划，并给出了分次内射模与内射模之间的一个关系。

Graded injective module is one of three modules in graded category of modules. This note contain some characteristic properties of graded injective modules. A relation is also given between graded injective module and injective medule. These results extend the conclusions in R - mod.
