摘要
仿紧性是模糊拓扑学中的重要概念,在LF闭包空间中仿紧性的基础上,介绍了可数仿紧性,并刻画了其基本特征.研究了LF闭包空间中可数仿紧性的性质:对C∨ech闭包算子的像集可遗传,是"L-好的推广",具有LF弱同胚不变性.
The paracompact is the important property of the F-topology spaces.The concept of countably paracompact is introduced based on the paracompact in LF cloure spaces.Its characteristics are studied.The properties of countably paracompact in LF cloure spaces are investigated：hereditary with respact to sets asC∨echcloure operator,it is proved that the countably paracompact is ＂L-good extension＂,and with weakly invariant with embryo.
