The effect of different heat treatment factor on pvc crystallinity was studied firstly in this paper 本文首先通过热处理研究了不同因素对pvc结晶度的影响。
Anneal make film easy to be crystallized too . at the same time a part of element is oxidated . 3 ) ( 2 )颗粒膜随膜厚的增加，成分含量的增多，该成分的结晶度提高。
The ideal heat treatment time was about 2 hours and the maximum crystallinity appeared at 130 掳 c 热处理时间在2h左右有较好的效果，而热处理温度在130左右出现最高结晶度。
Nano - caco _ ( 3 ) only affects blends " degree of crystallization , but do not affect the crystallization structure 一caco3只对树脂体系的结晶度有轻微的影响，不影响晶体的结构。
The research result indicated that heat treatment time and heat treatment temperature had effect on pvc crystallinity 研究结果表明：热处理温度和热处理时间对pvc的结晶度都有一定的影响。
Because chitin has a high degree of crystallinity , it can only be dissolved in expensive organic solvents 摘要由于天然甲壳素结晶度高，在湿法纺丝过程中溶解甲壳时需要使用价格较高的有机溶剂。
Low density polyethylene has a crystallinity range of 65 percent , and high density polyethylene ( has a crystallinity range ) of 85 percent 低密度聚乙烯的结晶度为65 % ，而高密度聚乙烯的结晶度为85 % 。
While adding ydh151 to this system , the torque decreased and the melting temperature and the degree of crystallization of the matrix increased 而对于hdpe基体， mmt的加入并没有影响体系的熔融温度和结晶度。
The results show that , core - shell impact modifier can act as nucleation agent , which can increase the crystallinity of nylon 11 blend alloy 实验结果显示，核-壳冲击改性剂具有成核剂的作用，有助于共混体系结晶度的提高。
( 3 ) after modification , the crystallinity and orientation of uhmwpe fiber has no obvious change , but the crystal size decreases greatly 纳米粒子的加入对纤维的取向度、结晶度基本没有影响，而纤维的晶粒尺寸大大降低。
