结晶度

To detect the crystallinity and orientation of fibroin fibers.

测定丝素纤维的结晶度和取向度。

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。

The resource of ramie is abundant in China, therefore, how to utilize it efficiently and profitably is of great importance.

但是，苎麻纤维素结晶度、取向度高，从而限制了其产品的深度开发和利用。

X-ray diffraction techniques were used to measure the degree of crystallinity and the orientation of flax fiber during retting.

采用X射线衍射法研究温水浸渍法脱胶和酶法脱胶过程中亚麻纤维结晶度、取向度的变化情况。

The findings showed that the crystallinity of flax fiber increased in a certain degree and the orientation had no significant change after both retting techniques.

结果表明：无论是温水浸渍法脱胶还是酶法脱胶，亚麻纤维的结晶度在脱胶过程中经过一系列的变化，最后都有一定程度的提高，而亚麻纤维的取向度在脱胶过程中自始至终都无明显变化。

Sound velocimeter and X-ray Diffractionwere used to measure the crystallization and orientation of the fiber.

通过采用声速仪、X-射线衍射等分析与检测手段对纤维取向度和结晶度进行了测定。

One novel polysaccharide—bacterial celluloseproduced by Acetobacter xylium have many distinguishing features, such as high purity, high crystalline great strength , high hydrophilic and good adsorption capacity.

细菌纤维素是微生物发酵过程中分泌的胞外多糖，由于其结构规整，聚合度强，纯度极高，结晶度高等特点，使其具备了独特的性能如高的吸水持水性和高的吸附性能等日益受到人们的关注。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。

We have successfully synthesized two high-performance polys, 6F-PEEK and m-TPEEK.

但无定形区的老化并不能从根本上影响较高结晶度的PEEK的结晶行为，无定形区的总量没有明显变化。

The results show that HDPE pipe prepared by vibration extrusion has higher crystallinity, higher melting temperature, larger lamellar thickness, larger crystal size, and more perfect crystals, and the slow crack growth resistance of HDPE pipe is improved.

结果表明：振动挤出的HDPE管材结晶度提高，熔点升高，晶片变厚，晶粒尺寸变大，结晶完善，耐慢速裂纹增长性能提高。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
