摘要
在Ｌ－Ｆｕｚｚｙ拓扑空间中给出了半内部、半闭包，半边界和半正则的定义，讨论了它们的性质，并借助于它们给出了半开集、半闭集、正则开（闭）集的等价刻划。
In this paper,the concepts of semi-interior,semi-closure,semi -boundany and semi-regular in a L-Fuzzy topological space are defined and studied.With the concepts,Some equivalent characteriztions of semi-open(closed)set,regular open (closed)set are given.
