摘　　要：在弱L-余拓扑空间引入Cδ-远域和-αCδ-远域,定义了紧集和紧空间的概念,给出紧集的等价刻画.通过引入具有有限交性质的弱闭集族给出紧空间的一个新特征.Some concepts, such as Cδ-remote neighborhood,a -Cδ-remote neighborhood family,compact set and compact space in the weakly L-catopology spaces are defined. The equivalent conditions of compact set are investigated. And we introduce the weakly closed subsets which have the finite intersection property and by that we portray the characterization of compactness.
