摘要：
A method for estimating the degree of crystallinity of cellulose in various physical forms through optimization procedures based on pulse NMR data is considered. A mathematical model adequately describing the decrease in the magnetization is chosen; the parameters of this decrease make it possible to determine the degree of crystallinity of polysaccharides.
