通过用柱形水力旋流器对漂白化学热磨机械浆进行筛分的实验，获得了分流与流场相互关系的新认识。

After research on the fractionation of softwood BC TMP pulp fiber by a cylindrical hydrocyclones, a new knowledge of the relationship between split ratio and flow field in hydrocyclones was gained.

过氧化氢在没有大量减少纸浆产量情况下，具有消除发色基团的良好选择性，所以它在高白度机械浆的生产中是主要的漂白化学品。

Hydrogen peroxide decreases the pulp yield slightly and has the good selectivity to eliminate the chromophores. So it's an important bleaching agent in the high-brightness Mechanical pulp production.
