<正>分析了稻秸木材复合工艺配比及防水剂的添加量（0.8%、1.2%、1.6%、2.0%）对稻秸木材复合中密度纤维板性能的影响。结果表明：采用稻秸与木材原料分别进行纤维分离，再混合后施胶的复合工艺，当草木配比为1：1，肪水剂加量为1.2%，脲醛树脂胶粘剂的施胶量为12%时，生产出的稻秸/木材中密度纤维板，除吸水厚度膨胀率外，各项性能均能达到中密度纤维板标准要求。

The properties of xylooligosaceharides separation by gel permeation chromatography was investigated. Xylooligosaecharides was separated with Bio-Gel P-4 by the first time and Bio-Gel P-2 by the second time. The results showed that the purity of fraction xylobiose, xylotriose, xylopentaose, xylohexaose and xyloheptaose separated with Bio-Gel P-4 were 98.18%, 88.54%, 97.52%, 78.80% and 86.67%, respectively. The content of arabinosyl groups in xylooligosaccharides was 14.75%, and xylobiose and xylotriose were not substituted with arabinosyl groups. The purity of fraction xylotriose can be raised from 88.54 % to 94.19% with Bio-Gel P-2 by the second separation.
