It is shown that every finitely generated right R-module is almost injective if and only if every cyclic right R-module is almost injective, if and only if R/J(R) is a right SV-ring with Loewy(RR)2 and there is a finite set of orthogonal idempotents {ei}iI in R such that eiR is an injective local right R-module of length two for every iI and J(R)=iIJ(eiR).

在具有循环几乎单射模块的环上

证明了每个有限生成的权利 电阻-module 几乎是单射的当且仅当每个循环权 电阻-module 几乎是单射的,当且仅当 电阻/J(电阻) 是权利 -环与 洛维(电阻电阻)2 并且有一个有限的正交幂等集 {电子一世}一世一世电阻 以至于 电子一世电阻 是一个内射的地方权利 电阻-每个长度为 2 的模块 一世一世J(电阻)=一世一世J(电子一世电阻).
