支持向量机结合近红外光谱法测定杉木木质素的含量
Determination of Lignin Content of Chinese Fir Wood by Support Vector Machine and Near-infrared Spectrometry
摘要
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 establish a model for determing lignin content.The square sum of relative calibration error and relative prediction error were 0.007433 and 0.001219,respectively,which demonstrated that this method is precise for determination of lignin content of Chinese fir wood.关键词
