摘要
利用θ-开集引入了拓扑空间的θ-Ti(i=0,1,2,3,4)分离性概念,给出了它们的刻画,证明了它们都是θ-拓扑性质和拓扑性质,它们与T分离性的关系为:
In this paper θ-Ti （i=0,1,2,3,4）separation concepts on general topology are introduced by θ-open sets, Characterizations of them are given. It is proved that they are θ-topological and topological properties. It is proved that relation between θ-Ti separation and T separation are：
θ-T4→θ-T3→θ-T2→θ-T1→θ-T0

T4→T3→T2→T1→T0
