摘　　要：稀土应用于混合阔叶材硫酸盐浆的氧碱漂白中，引起纸浆质量和性能的变化。本文介绍了用Ｒｕｌａｎｄ法分析纸浆的绝对结晶度，研究了稀土氧碱处理后纸浆结晶度的变化，对稀土在纸浆氧漂中的行为及其对纸浆纤维素的作用进行了探讨。Properties of kraft pulp were improved in oxygen bleaching when rare earth was introduced as protective agent.In this paper,absolute crystallinity of pulp was deteminded by Ruland method and changes of pulp crystallinity was studied.The mechanism of reaction between rare earth and pulp fiber was discussed preliminarily.
