1.
Based on the definition of fuzzy semi-preopen sets, the concepts of fuzzy lower and upper almost semi-precontinuous mulitifunctions as well as fuzzy almost semi-precontinuous mulitifunctions are introduced.
在模糊半预开集的基础上,引入了模糊下与上几乎半预连续多值映射的概念,借助于映射F*与F*研究了它们的性质及其等价刻画。

模糊预半开集
4) fuzzy neighborhood
模糊邻域
1.
The concepts of fuzzy ball,fuzzy press-ball and fuzzy neighborhood were proposed in this paper,which were employed to describe the fuzzy nature language words nearby a point or about a number .

准半开邻域
6) strongly semiopen neighborhood
强半开邻域
1.
In this paper, weak T*-separation axioms in topological molecular lattices are introduced and studied by using strongly semiopen neighborhoods.
利用强半开邻域引入和研究了拓扑分子格的弱Ti*分离公理,这是TI*分离公理的 推广(I=1,2,3,4)。
补充资料：半预聚物工艺
分子式：
CAS号：
性质：又称半预聚物工艺。在用预聚法制备聚氨酯制品时，若聚合反应物料的异氰酸酯基同羟基的比例大于2，生成的预聚物两端为异氰酸酯基团，体系内保有一部分未反应的活性异氰酸酯，此体系称准预聚物，以这种准预聚物为基础进行扩链或聚合的工艺即准预聚物工艺。
