fine dispersion meaning in English

精细分散

Compared with the two kinds of composites , silicate layers gained much finer dispersion in the pvc matrix due to the special process
将两种体系复合材料的力学性能相对比表明原位插层体系各项力学性能均明显优于熔融插层体系。
Other work has concentrated on materials ranging from nonprecious metal catalysts such as cobalt and chromium to catalysts consisting of fine dispersions of particles embedded in porous composite structures
其他研究工作则著重于别的材料，涵盖钴或铬等非贵金属，以及成份为嵌于多孔复合物结构中的微小颗粒的触媒。
The structure of the composites was characterized by x - ray diffraction and transmission - electric microscope . the experimental results showed that the in - situ intercalation realized much finer dispersion of the silicate layers in the pvc matrix than the melt - blending intercalation . as for as the properties of the composites , the well - dispersed organoclay in the composites improved the properties of the materials , especially for the viscat softing temperature
本文主要通过x射线衍射、透射电子显微镜对复合材料的结构进行表征，结果证明：原位插层复合材料中粘土片层基本剥离，均匀的存在于聚氯乙烯树脂基体中；熔融插层体系中粘土的分散状态明显劣于原位插层体系，粘土以一定量片层堆积的形式存在。
