摘要(Abstract)：

凝固成形和拉伸是原丝生产过程中两个十分关键的工序,它们对聚丙烯腈原丝的结构和性能有着重要的影响。纤维的拉伸强度在凝固成形过程中受到凝固浴浓度、温度和负拉伸的影响,同时在纤维的拉伸中拉伸的倍数、温度和介质等也影响着纤维的结构和性能。
Coagulation and stretch are two crucial working procedures during precursor fabrication, which play important roles in precursor structure and performance. The fiber tensile strength is affected by concentration, temperature and minus stretch during coagulation, while the fiber structure and performance are obviously in- fluenced by stretch temperature, medium and ratio.

关键词(KeyWords)： 凝固;拉伸;聚丙烯腈原丝;拉伸强度
