| Abstract: | 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. |
