| 摘 要： | 讨论扩大(G,H)-分次环上投射模的性质,得到扩大(G,H)-分次R-模范畴R(G,H)-Agr是个有足够多投射对象的Abel范畴,以及P是Agr-投射模当且仅当P是投射R-模等结论.

| Abstract: | Discusses the properties of projective modules of augmented (G,H)-graded rings,obtains that R(G,H)-Agr is an Abelian category with enough projective objects,and gets that P is an Agr-projective module if and only if P is an projective R-module. |
