摘要
对电子束辐照处理后的滤纸、木屑和稻草三种纤维素材料的Ｘ衍射行为进行了较为系统的研究。结果可见，这三种植物纤维素材料的相对结晶度都随辐照剂量的增加而减少。同时还发现它们的Ｘ衍射峰峰位都随辐照剂量增加而向小角方向位移，并呈线性关系。实验还发现木屑所含大量木质素并没有在电子束辐照场中对纤维素晶区起保护作用。
The X-ray diffraction spectra of filter paper, saw dust and rice straw were studied after they were irradiated with electron beam. The results show that the relative crystalline degrees of these three celluloses decrease linearly and the position of their X-ray diffraction peak shifts towards smaller angles with the increasing irradiation dose. It is also shown that xylose in saw dust cannot protect the crystalline structure of cellulose against the electron beam exposure.
