The gel dynamics experiments showed that the gel formation law was similar with the other polymer systems, which wasrelated with dense surface under the soft coagulating condition and the thickening gel; the square of gel thickness was linear with coagulation time. The qualitative analysis of the surface puckers of fibers spun from wet spinning and dry-jet wet spinning was made. The positions where the die swell appeared were not the same and the die swell appeared at the air gap where the fiber would markedly been elongated and vary little in the coagulant, thus the surface of fiber spun from dry-jet wet spinning was more smooth. The radial component concentration gradient was responsible for the radial structure of PAN fiber spun from dry-jet wet spinning. The thicker surface with microvoid structure of

对湿纺和干湿纺进行比较表层沟槽的产生进行定性分析，原因在于孔口胀大区域出现在不同位置，在干湿纺中，溶液的孔口胀大出现在空气层，并在该区完成大部分形变，进入凝固浴后形变很小，纤维表面较为光滑；干湿纺PAN纤维径向结构存在差异，这与丝条内组分由于双扩散进行导致径向上存在浓度差异直接相关；凝固强度较大的体系，可以获得厚度较大且孔结构尺寸较小的皮层；含较少缠结的PAN原液在纤维成形后截面很圆整，但原液缠结浓度增大时成形后圆整度下降；PAN纤维成形是一个远离平衡的过程，凝固作用缓和的体系可以使成形过程靠近平衡，可获得更大尺寸的孔洞结构；原液中少量的非溶剂添加剂显著改变纤维径向结构，可获得孔洞尺寸更小和更为均一的径向结构，这与径向浓度差异的减小、分相时间的集中相关；PAN原液的成形纤维表面依赖于凝固强度；由AFM对相近凝固条件下成形的PAN膜进下
