中文摘要：
研究了沙柳P-RC APMP进行酶处理后浆料性能的变化。结果表明，与空白样相比，聚木糖酶处理、漆酶／介体处理和漆酶／聚木糖酶处理对浆料光学性能的影响各不相同，浆料裂断长分别降低了9．5％、0．8％和6．7％，耐破指数分别降低了11．0％、4．1％和13．8％，撕裂指数分别提高了8．3％、8．0％和1．3％；扫描电镜观察发现，聚木糖酶处理后浆料纤维表面细纤维化程度变大，漆酶／介体处理后浆料纤维表面比较光滑，并出现部分表皮大块脱落的现象，与前述纤维相比，漆酶／聚木糖酶处理后的纤维分丝帚化程度最高；x射线衍射分析发现，酶处理后浆料纤维素的结晶度均下降，分别降低了6．0％、5．9％和2．4％。
英文摘要：
The effect of enzyme pretreatment on the properties of Salix Psammophila P-RC APMP was studied. The effects on optical properties of the pulp from pretreated Salix Psammophila by xylanase, laccase medium and laccase/xylanase were all different, the breaking length of the pulp reduced by 9.5%, 0.8% and 6.7%, and the bursting index reduced by 11.0%, 4.1% and 13.8%, the tearing index im- proved by 8.3% , 8.0% and 1.3% respectively compared with the pulp from unpretreated new material. X-ray diffractometer analysis indi- cated that the crystallinity of the cellulose reduced after enzyme pretreatment.
