摘要:研究了各种未打浆纸浆的纤维直径、长度与粗度的关系，并探讨了纤维长度与粗度对成纸性能的影响。结果表明，纤维的直径、长度与粗度成线性关系；且纤维长度与粗度均对成纸的吸水性、气孔率与气孔有效直径有增强作用。

Abstract:This study dealt with the effects of fiber length， coarseness and length distribution on the stereo structural properties of paper produced from unbeaten pulp.At the same time， the relationship between weight average fiber length and stereo structural properties of paper was investigated.In this investigation， it was found that a positive relationship was observed between weight average length and stereo structural properties of paper.The correlations between length and stereo structural properties of paper were very good.Regression analysis indicated that stereo structural properties of paper was more clearly a function of fiber length and coarseness．
