The concepts of a net of LF sets and its convergence in an LF topological space are introduced, their properties are systematically studied, and more interesting results are obtained.
在LF拓扑空间中引入LF集网及其收敛性等概念，系统地研究了它们的性质。

This article has introduced topological space Xs property of sequencable convergence and proved that this property is quotient property.
引进拓扑空间x的可序列收敛性质，证明了这一性质是可商的性质。
