摘　　要：证明 L- Fuzzy拓扑空间中强导集的点式杨忠道定理 ,并用反例表明强导集的分子式杨忠道定理不成立。In this short paper, the C.T.Yang′s theorem concerning strong derived sets has been proved for L fuzzy points, and moreover, an example is given, which illustrates the C.T.Yang′s theorem concerning strong derived sets does not hold for L fuzzy molecules.
