摘　　要：研究了漆酶NS51003/介体体系(LMS)改性对未漂马尾松TMP纸浆H2O2漂白性能的影响,探讨了不同H2O2用量及漂白时间对纸浆光学性能、强度的影响。结果表明,LMS处理后纸浆的可漂性提高,白度增值最高可达4.04%ISO;成纸不透明度及吸收系数均有一定幅度下降;光散射系数几乎不受影响;纸页返黄值上升,物理强度均得到明显的改善。The masson pine unbleached TMP was treated with laccase together with a mediator and thereafter bleached with hydrogen peroxide（H2O2）. The influence of such factors as the dosage of H2O2 and the bleaching time on the pulp whiteness, bulk and strength were analyzed in this paper. At the optimum conditions, the TMP brightness increased 4.04%ISO compared to the sample pulp; the opacity and the light absorption coefficient decreased; the light scattering retained stabilization, the tensile index ,the PC and the tear index increased visibly.
