摘　　要：通过均匀设计试验法和回归分析得出落叶松锯屑液化工艺各因子之间的交互作用。使用凝胶渗透色谱仪对8种不同合成条件下的落叶松锯屑液化物样品进行检测,分别求得数均分子量和重均分子量。结果表明:无论液化条件如何,液化物的分子量仍是以大分子为主,且在液化物中以这样的高分子量片段为主。By means of uniform design experimentation and regression analysis, the interaction between various factors involved in the liquefaction process of larch sawdust is obtained. Through gel permeation chromatography, inspection is conducted of samples of liquefied larch sawdust obtained under 8 different synthesis conditions, with number-average molecular weight and weight-average molecular weight obtained respectively. The result shows that no matter what liquefaction conditions, the molecular weight of liquefied samples is dominated by large molecules, to be exact, high molecule weight segments.
