英文摘要：

The pretreating effects of poplar refiner mechanical pulp before stage Ⅱ refining with cellulase enzyme and xylanase on the modification of pulp performance and the reduction of energy consumption was researched. The effects of different dosage of enzyme on energy consumption were studied as well as the effects of different pretreating conditions on the pulping performance of poplar mechanical pulp, The results show that enzyme treatment can reduce refining energy consumption and improve pulp quality.
