摘要
对拓扑空间的开子空间的性质进行了研究,得出了定理1和定理2,并着重对S 闭空间的遗传性进行了探索,获得定理3和定理4,从而得出S 闭性是正则开可遗传性.
The properties of opened subspace of topology space are researched and theorem 2.1 and theorem2.2 are obtained.Then the genetic properties of S-closed space are studied and theorem 2.3 and theorem 2.4 are obtained.So a theory is given that S-closed property is opened genetic property.
