且仅当如果ker=ker，其中s，t∈S=End，那么Ss=S_t；(2)如果右R-模M是自生成子，那么右qpm-内射模M的自同态环是右pm-内射环。

In the second section, we extend the conception of right pm-injecitve from ring to module and obtain the notion of right qpm-injective module.

第二部分把右pm-内射概念从环推移到模上，引入右qpm-内射模的概念。

The result is that:(1) A right R-module M is right qpm-injective module if and only if for any s.t S = End with ker = ker, then Ss = St.

所得到的结果是：(1)右R-模M是右qpm-内射模当。
