摘　　要：借助θ-闭包引入BOs-θ连通性,WPOs-θ连通性及POs-θ连通性等概念,并研究了其若干性质,得出一族两两非WPOs-θ隔离的WPOs-θ连通集之并是WPOs-θ连通集,一族两两非POs-θ隔离的POs-θ连通集之并是POs-θ连通集。The concepts of BOs-θ connectedness, WPOs-θ connectedness and POs-θ connectedness were re- searched by θ-closure in the L-bitopologieal space. Their properties were investigated; The Union of a family WPOs-θ connected sets which cannot be WPOs-θ separated each other is WPOs-θ connected sets ; The Union of a family POs-θ connected sets which cannot be POs-θ separated each other is POs-θ connected sets.

关 键 词：L-双拓扑空间 BOs-θ连通性 WPOs-θ连通性 POs-θ连通性
