研究发现滤纸纤维素材料在电子束辐射裂解过程中，Ｘ射线衍射峰（００２、１０１、１０１峰）的峰位均随辐照剂量的变化呈规律性变化。根据实验数据分析，电子束射线裂解了纤维素晶格和非晶处界面的分子，引起纤维素微晶尺寸变小，使纤维素Ｘ衍射峰发生向小角方向位移。实验中还发现辐照的滤纸放置４个月后，其００２峰的峰强明显小于辐照后立刻测得的数据，这可用辐照后效应来解释。 It was found that the peaks of the X-ray diffraction peaks (002, 101, and 101 peaks) of filter paper cellulose materials changed regularly with the irradiation dose during the electron beam radiation pyrolysis. According to the experimental data analysis, the electron beam ray cleaves the molecules at the interface between the cellulose lattice and the amorphous interface, causing the size of the cellulose crystallite to become smaller and displacing the X-ray diffraction peak to a smaller angle. Experiment also found that the irradiated filter paper placed 4 months after the peak intensity of 002 was significantly less than the data measured immediately after irradiation, which can be explained by the post-irradiation effect.
