摘　　要：本文研究Gorenstein投射模的特征模,给出了右凝聚环是左完全的一些等价刻划,得到了Gorenstein投射模类是预包类的一个充分必要条件.We investigate character modules induced by Gorenstein projective mod- ules. In particular, we give a necessary and sufficient condition for a right coherent ring to be left perfect. As an application, we characterize when the class GP of Gorenstein projective left R-modules is preenveloping.
