摘　　要：本文以远域理论为工具引入了Ｌ－双Ｆｕｚｚｙ拓扑空间中的Ｌｉｎｄｅｌｆ性质，讨论了这类空间的一些性质。证明了Ｌｉｎｄｅｌｆ性质是闭遗传的、双强同胚不变量，最后给出了在弱诱导拓扑空间中，Ｌｉｎｄｅｌｆ性质的几个等价条件。By the use of remote-neighborhoods Lindelof property in L-bifuzzy topological spaces is introduced ,with some properties of such kind of spaces discussed;It is proved that Lindelof property is a kind ot closed hereditary and bistrong topologlcal invariant. Some equivalent conditions of Lindelof property in weakly induced topologital spaces are also given.
