With increasing blow up ratio , both the axial orientation and the crystallinity of tubular films increase . with increasing draw down ratio , only the axial orientation increases while the crystallinity does not change significantly 管膜的结晶度随吹胀比的增加而增大,当拉伸比增加时结晶度没有明显变化。
With the temperature increasing , the grains of the lanio3 samples grew large steadily and the crystallinity became better . it can be seen that the lattice were prolonged along the a axle while shrinked along the c axle 随着烧结温度的升高, lanio _ 3样品的晶粒尺寸变大,结晶完善,晶格在a轴方向上伸长,在c轴方向上收缩。
The result showed that with increasing of hard segment content , the crystallinity of copolymer increased , thehard se gment content and the molecular weight of polyether were influence on the mechanical properties of copolymers 结果表明,共聚物的结晶度随聚酯硬段含量的增加而增加,而其力学性能则受聚酯硬段含量和聚醚分子量的影响。
With an increase of nmmo concentration of coagulation bath or concentration of casting solution , the crystallinity of membrane increases . however , an increase of temperature of coagulation bath is accompanied by a decrease of crystallinity of membrane 膜的结晶度随铸膜液浓度、凝固浴浓度、刮膜速度的增加而增大,随凝固浴温度的升高而降低。
When polyester fiber is subject to different draw ratio and heating temperature during high speed spinning , it will result in changes of the original molecular orientation and crystallinity of the fiber , thus affecting its physical properties 摘要在高速纺丝过程中对聚酯施以不同的拉伸倍数与温度,会造成纤维结晶度与取向度的变化,从而影响纤维的物理性能。
