| Abstract: | In this paper,the s-pure quasi-injective modulesare intriduced and some properties of s-pure 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. |
