摘要：利用X射线衍射仪，对γ射线辐照处理前后的竹材进行X射线光谱分析，得出竹材结晶度和微纤丝角在辐照过程中的变化规律。随着辐照剂量的增加，竹材纤维素结晶度呈现先升高后降低的趋势，微纤丝角变化不明显，表明微纤丝角不是影响辐照过程中竹材物理、力学性能变化的主要因子。

Abstract：The microfibril angle and crystallinity of bamboo treated with γ rays were tested by X-ray diffraction (XRD). The result indicated that crystallinity in bamboo increased when irradiation dose was less than 100 kGy, while the irradiation dose was raised to about 100 kGy, crystallinity in bamboo reduced. But during the whole irradiation process, the influence on microfibril angle was not obvious, so it was not the dominant factors on variation in physical-mechanical properties of bamboo during the process of irradiation.
