| 摘 要： | <正> 结晶学家认为低分子物结晶虽可能存在一定缺陷和变形,但一般都具有一定的晶胞参数。这一概念对于高分子物结晶已不再正确。Bosley认为成形、热处理、冷却速率和杂质的存在皆可引起晶格变形;Fakirov故意在PET中加入少量杂质,却未引起变形。至今,PET已累积了7组晶胞参数,8个计算所得的晶区密度显示了较大幅度的波动(见

| Abstract: | Analysis of these experimental results indicated that the crystal structure of polymer fibers differs from that of the small molecular weight substances in that the crystal cell parameters of the former are much more influenced by the internal stresses left in the fiber during the heat setting of the drawn polymer fibers. |
