将超声波应用在木质纤维素预处理及其酶解糖化过程中，通过SEM、FTIR研究了处理前后纤维素的形态结构和结晶性能，并考察了不同预处理方式对原料 成分的影响和超声波对酶解糖化率的影响。结果表明，超声波作用能有效的破坏纤维素分子中的氢键，降低其结晶程度，而且能有效地提高木质素的脱除率和酶解糖化率。对超声波作用于酶解过程中的机理进行了初步探讨
Both pretreatment of lignocellulose and its saccharification process are treated with ultrasonic wave. The morphology, structure and crystal performance of the original and treated lignocellulose sample were characterized by SEM and FTIR. Moreover, the changes of raw materials caused by different pretreatment ways and the affect of saccharification rate brought about by ultrasonic wave were also studied. The result shows that the ultrasonic wave decreases the crystallinity of lignocellulose destroying the intermolecular hydrogen bonding effectively and improves the degradation rate of lignin and the saccharification rate of zymohydrolysis availably. The mechanism of activation of ultrasonic wave in zymohydrolysis process was discussed primarily.
