1·Carbon fiber is produced by dry-wet spinning of copolymerized PAN followed by preoxidation and carbonization.
本文采用干湿法纺制共聚丙烯腈纤维，并进行预氧化，碳化制成碳纤维。
2·Catalyst processing method is used to speed up the preoxidation of polyacrylonitrile fibre. The catalysis results are evaluated with the aid of DSC curves.
为加快聚丙烯腈纤维的预氧化速度，采用催化剂处理方法，借助于DS C曲线来评定催化效果。
