Experimental research on defects of L-shape laminates in vacuum-bag process;

L形層板真空袋成型缺陷的實驗研究

Also,the properties of operators ω and the concepts of induced L-smooth topological space,weakly induced L-smooth topological space and stratified L-smooth topological space were given.

引入L-fuzzifying拓撲空間及生成L-smooth拓撲空間的概念,研究了-Lfuzzifying拓撲空間(X,τ)與其相應的生成-Lsmooth拓撲空間(LX,ω(τ))的關系;介紹了ω算子及其運算性質;給出并研究了L-smooth誘導空間,L-smooth弱誘導空間,L-smooth滿層空間的定義和它們之間的聯系。
