摘　　要：采用模糊关系方程法研究了植物纤维浆料流变特性,分析了浆料纤维长径比、浆料浓度、浆料温度和浆料气液比对浆料流变性的影响,建立了估计模型y=(0.72∧x1)∨([0,0.5]∧x2)∨(0.32∧x3)∨([0,1]∧x4).结果表明,利用此模型估计植物纤维浆料流变特性效果较好.植物纤维浆料的流变特性受到以下因素影响的程度大小排列如下:浆料纤维长径比(即纤维种类)>浆料浓度>浆料温度>浆料气液比.The rheological properties of plant fiber pulp was studied using the method of fuzzy relation equation,and the effects of pulp factors including fiber length-diameter ratio,concentration,temperature and gas-liquid ratio on rheological properties were analyzed,and a estimating mold,y=（0.72∧x1）∨（∧x2）∨（0.32∧x3）∨（∧x4）,was set.The results showed that the estimating consequent by the mold was perfect,moreover,the rheological properties of plant fiber pulp were influenced by following factors（from greatly to little）： pulp fiber length-diameter ratio〉pulp concentration〉pulp temperature〉 pulp gas-liquid ratio.
