The results showed that gas permeation mainly occurs in amorphous region of the PMP, but also in the crystallineregion.
结果表明,气体的透过主要发生在PMP的无定形区域,但也在PMP的晶区进行。

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