crystalline region

The XRD results indicate that the esterification of starch mainly occurs in the amorphous region and less in the crystalline region.

XRD分析表明，酯化反应主要发生在淀粉分子非晶区，在结晶区也有一定程度的反应；

It was considered that the mechanical properties of PAN precursor was better when the orientation degree in crystalline region and overall orientation factor were about 0. 9 and 0.8, respectively.

综合考虑取向因子对纤维结构性能因素的影响，认为PAN原丝晶区取向因子约为0.9、总取向因子约为0.8时，纤维力学性能较好。
