| 摘 要： | 用小角X射线散射法对辐照聚乙烯在不同条件下拉伸及热处理后的长周期进行了研究。在室温拉伸时长周期减小,拉伸试样再热处理时,长周期又逐渐增加。这可用结晶的破坏以及重结晶来解释。

| Abstract: | Long period of irradiated polyethylene strectched and thermally treated under different conditions has been studied by small-angle X-ray scattering.It is shown that long period reduces when the samples are stretched at room temperature. However it increases after thermal treatment. These results can be explained by the breakdown of crystalline structure at first and recrystallization afterwards. |
