摘　　要：给出开性度模糊拓扑空间的分解定理和判定定理，引入保度开（闭）映射的概念并讨论其简单性质，最后证明了一个形成新开性度模糊拓扑空间的定理。Decomposition theorem and a decision theorem of gradation of open-ness of fuzzy topological spaces are given in this paper.The concept of gra-dation Preserving open(closed)mapping and then study their properties are-obtained.The theorem of induced gradation of openness of fuzzy topologicalspaces is also discussed.
