【摘要】 用红外光谱法和X射线衍射法,分别测定了经60Coγ射线辐射和高能电子辐射后精制棉纤维素的结晶度指数和相对结晶度.证实当吸收剂量范围为2×103Gy到80×103Gy时,辐射对棉纤维素的结晶度基本上没有影响.同时也比较了两种测定方法的优缺点.

【Abstract】 After being radiated by 60Co γray and high energy electron,the crystallinity index and relative crystallinity of refined cotton cellulose were determined by imfrared spectra and X-ray diffraction,respectively.It is found that the crystallinity of the cotton cellulose is retained basically as the absorption dose varied from 2×103Gy to 80×103Gy.The advantage and disadvantage of the two determination methods were also compared.
