分子堆积 meaning in English

packing of molecules

The obstruction that the mere fluid receives while flowing in different medium is different , make the velocity of flow different too , cause and refract light the index to be different , and between size and medium molecule of obstruction effort size and medium intensive degree that member pile up have something to do
摘要光流体在不同介质中流动时所受的阻力不同，使得流速也不同，导致折光指数不同，而阻力的大小与介质分子间作用力大小及介质分子堆积的密集程度有关。
The crystalline structure changes of pp induced by pan - milling were characterized by x - ray diffraction and raman spectroscopy . xrd analyses show that when pp was co - milled with uhmwpe , crystal transformation of pp occurred , its crystallinity and crystallite size decreased , whereas , only slight reduction of crystallinity and crystallite size were observed and no crystal transformation was found when pp was co - milled with wtr chips , and amorphization of pp was strongly enhanced by co - milling pp with iron
采用x -射线衍射研究了聚丙烯碾磨粉碎过程微观结构变化， uhmwpe存在下pp发生晶型转变、结晶度降低和晶粒尺寸减小；弹性材料wtr抑制pp塑性变形，碾磨导致分子堆积有序区域膨胀，晶面间距增大，结晶度下降；刚性材料金属铁与pp产生强烈摩擦，加快晶粒细化，晶格破裂导致非晶化。
