1·The PHB homopolymer is a stiff and rather brittle polymer of high crystallinity, whose mechanical properties are not unlike those of polystyrene, though it is less brittle.
在PHB的均聚物是一种高结晶度，其不同于那些不聚苯乙烯力学性能，比较脆硬聚合物，虽然它是那么脆弱。
2·With the rise of the coal rank, the crystallinity of kaolinite and its order in the anthracite bed go up.
随着煤变质程度的升高，煤层夹矸中高岭石的结晶度、有序度也随之升高。
3·Some important characteristics of polymers include their size (or molecular weight), softening and melting points, crystallinity, and structure.
聚合材料具有一些重要特性，包括尺寸(或分子量)、软化及熔化点、结晶度和结构。
4·The results showed that the effects of ECAE processing on density and crystallinity of PP were minor.
研究表明，一次和二次ecae加工对P p结晶度和密度的影响较小。
5·To detect the crystallinity and orientation of fibroin fibers.
测定丝素纤维的结晶度和取向度。
