摘　　要：本文首先讨论了Ｌ─ｆｔｓ中ＬＦ集的聚点的分布；其次讨论了ＬＦ集的导集的一些性质，并给出了一般的Ｌ─ｆｔｓ中类似于杨忠道定理的结果；本文最后引进了导算子的概念，并用其刻划一般的Ｌ─ｆｔｓ．In this paper, we first study the distributional rules of the accumulation points of the LF-sets,Then we give some properties and C.T.Yang's theorem concerning derived sets in the L-fuzzy topological spaces,Finally we introduce the derived operator on Lx and by which we characterize the L-fuzzy topological spaces.
