速生材制浆性能与其材性的多元非线性回归分析及预测方法

Forecasting Methods of Pulping Properties of Fast-Growing Woods with Multiple Nonlinear Regression

采用多元非线性回归方法分析速生阔叶木材的制浆得率与其化学组分、纸浆的抗张指数、撕裂指数分别与纤维形态的相关性,建立速生材制浆性能的预测模型,选取代表性的速生木材进行材性分析和制浆性能试验研究,用实测值与预测模型算出预测值进行对比。结果证明:预测值与实际测定值拟合得很好,预测模型的精度高。

In this paper,multiple nonlinear regression was used to analyze the relativities of pulping yield and chemical composition,tensile index and tearing index and fiber morphology.The prediction model of pulping properties of fast-growing woods has been established.Chemical composition and pulping properties of three representative fast-growing woods have been studied to verify forecasting models.The result shows that the forecasting value fitting well with the actual value,and the prediction models are feasible.
