摘　　要：用AU-MTPE90酶和酸性木聚糖酶对搓磨分丝后的马尾松木片进行预处理,并利用纤维质量分析仪研究酶用量对纸浆纤维的影响。结果表明:AU-MTPE90酶和木聚糖酶处理后,马尾松浆料纤维的平均长度提高,细小纤维含量降低;AU-MTPE90酶预处理浆料的卷曲度跟扭结度都增大,木聚糖酶预处理马尾松浆料后的卷曲度和扭结度均降低。We used AU-MTPE90 enzyme and xylanase to pre-treat screw compressed Masson pine wood chips. By using FQA to study the effect of enzyme dosage to pulp properties. The result showed that： the average fiber length increased greatly after pretreated by AU-MTPE90 enzyme and xylanase, while the amount of fines decreased .The curl index and kink index declined after pretreated by AU-MTPE90 enzyme, while after xylanase prtetreament, the curl index and kink index increased.
