摘　　要：纸浆硬度是衡量纸浆残余木素或脱木素程度的重要指标。本文归纳、分析、比较了几种常见的离线或在线的纸浆硬度测定方法特点,并在文献数据的基础上,通过上机实验,定量地研究了纸浆卡伯值与残余木素之间的关系。The hardness of pulp is an important index to measure the degree of delignification of pulp or contents of residue lignin.Several common methods of testing pulp hardness on off-line or on-line are summed up,analyzed and compared in this paper.On the basis of literature data,the quantitative relationship between pulp kappa number and residual lignin are also studied.
