This paper mainly uses fpn-injective right R-modules to investigate fpn-injective covers,gives a characterization of the existences of monomorphic fpn-injective covers of right R-modules,and proves that every R-module M has a monomorphic fpn-injective cover :E→M if and only if R is a right fpn-hereditary ring.
通过fpn-内射模类来研究模的fpn-内射覆盖,给出了单的fpn-内射覆盖的存在性刻画,证明了每个右R-模M都有单的fpn-内射覆盖φ:E→M当且仅当环R为右fpn-遗传环。

右半遗传环
5) right cosemihereditary ring
右余半遗传环
6) graded right V-ring

1.
We prove that S is a graded right V-ring if and only if R is a graded right V-ring,S is graded PS-ring if and only if R is a graded PS-ring,and S is a Von Neumann regular ring if and only if R is a graded Von Neumann regular ring.
本文引进了分次环的分次Excellent扩张概念,设S=⊕_(g∈G)S_g是R=⊕_(g∈G)R_g的分次Excellent扩张,证明了S是分次右V-环当且仅当R是分次右V-环,S是分次PS-环当且仅当R是分次PS-环,S是分次Von Neumann正则环当且仅当R是分次Von Neumann正则环。
