| 摘 要： | 采用支持向量机(SVM)结合近红外光谱(NIR)技术建立测定杉木中木质素的定量分析模型。以47个杉木样品作为实验材料,用常规方法测定了样品中木质素的含量,用近红外光谱仪采集相应的光谱,对光谱数据进行平滑、求导、小波压缩以及归一化,结合支持向量机,以径向基(RBF)作为核函数,建立了测定杉木中木质素含量的模型。校正相对误差的平方和为0.007433,预测相对误差的平方和为0.001219。结果表明,该方法测量比较准确,可以用于杉木中木质素含量的预测。

| Abstract: | Via near-infrared spectroscopy(NIR)combined with support vector machine(SVM),a model for determining lignin content of Chinese fir wood was established.Forty-seven Chinese fir samples were used as experimental material.Lignin content of samples was measured according to wet-chemical method.The spectra of Chinese fir samples were recorded by near infrared spectrometer.The spectral data were pretreated by smoothing,derivating,compressing and scaling.Radial basis function(RBF) was used as kernel function to es... |
