通过X射线衍射法测定了纯化苎麻和丝光样品的纤维素I-β和纤维素II的泊松比。[200]/[004]纤维素I的泊松比为0.38。纤维素II的[200]/[004]为0.30，[110]/[004]为0.46。纤维素II的较小的[200]/[004]泊松比可归因于通过氢键和货车范德华力的更紧密的分子间缔合。纤维素II的泊松比[1（1）/bar 0]/[004]估计为负值。(C)2004 Wiley Periodicals，Inc.
Poisson's ratios of cellulose I-beta and cellulose II were determined for purified ramie and mercerized samples by X-ray diffractometry. Poisson's ratio was 0.38 for [200]/[004] of cellulose I. and 0.30 for [200]/[004] and 0.46 for [110]/[004] of cellulose II. The smaller [200]/[004] Poisson's ratio for cellulose II could be ascribed to closer intermolecular association through hydrogen bonding and van der Waals forces. Poisson's ratio for [1 (1) over bar0]/[004] of cellulose II was estimated to be negative. (C) 2004 Wiley Periodicals, Inc.
