摘　　要：在L-smooth拓扑空间中借助于L-smooth强半闭集给出了L-smooth sr-远域、sr-附着点、sr-聚点等概念,并以此为基础讨论了分子网的sr-收敛理论,研究了它们的一些基本性质.从而,丰富了已有的结果.The concepts of L-smooth st-remote neighbourhood, st-cluster point and st-limit point are given by means of L-smooth strong semi-closed sets in L-smooth topological spaces. Based on these concepts, st-convergence of molecule net are discussed and some of their basic properties arc studied. Therefore, the existing results are enriched .
