| 摘 要： | <正> 高聚物薄膜如聚对苯二甲酸乙二酯(PET),聚碳酸酯,硝酸纤维素等经铀核裂变碎片轰击后,再用化学试剂蚀刻,可以显示核裂片在高聚物薄膜内的经迹,这已在核物理研究中得到很好的应用。本文应用核经迹法对PET不同取向和结晶程度的试样进行了观察,认为该方法对于研究高分子聚集态结构是有深入探讨意义的。

| Abstract: | 235U fission track observations have been performed for PET samples stretched and heat treated under different conditions.These damage tracks may be revealed and made visible in an ordinary optical microscope by treatment with KOH solution that rapidly and preferentially attacks the damaged material.As the stretching and annealing of PET films caused change in the state of mae-romolecular aggregation in the film, the diffusion-etching rate of KOH solution will be accordingly changed. Anisotropy in the diffusion-etching rate gives usanisotropy in the diameter of track cross-section. |
