一种水相脱卤催化剂的红外光谱解析

水相脱卤催化剂PVP-PdCl2-MnCl2/GLM-PEG400,用于催化难溶于水的芳香卤化物水相脱卤,对芳香卤化物呈现出高的脱卤活性.通过IR光谱表征探讨了催化剂各组分在催化脱卤中的作用.     

L-型模糊格蕴涵代数

This paper introduced the concept of L-fuzzy sub lattice implication algebra and discussed its properties. Proved that the intersection set of a family of L-fuzzy sub lattice implication algebras is a L-fuzzy sub lattice implication algebra, that a L-fuzzy sub set of a lattice implication algebra is a L-fuzzy sub lattice implication algebra if and only if its every cut set is a sub lattice implication algebra, and that the image and original image of a L-fuzzy sub lattice implication algebra under a lattice implication homomorphism are both L-fuzzy sub lattice implication algebras.
