摘要
本文给出了s-纯拟内射模的概念,讨论了s-纯拟内射(预)覆盖一些性质.并证明了s-纯拟内射模关于直和因子封闭.
In this paper, the s-pure quasi-injective modulesare intriduced and some properties of sZpure quasi-injectivemodules are studied. It is prove that s-pure quasi-injective modules is closed under direct summand. Some properties of s-pure quasi-injective （pre）cover and s-pure quasi-injective cover are discussed.
