| 摘 要： | 运用近红外光谱技术结合偏最小二乘法(PLS),对所采集光谱进行一阶导数和二阶导数处理,并对未处理原始光谱、一阶导数处理光谱和二阶导数处理光谱分别在7个不同波段范围内建立红松含水率预测模型.结果表明红松样本近红外光谱经一阶导数处理,波段在1 000～2 100nm范围内所建模型最优,其校正集相关性系数为0.992 5,校...

| Abstract: | A study was conducted to examine the feasibility of using near infrared(NIR) spectroscopy analysis combinded with parial least squares regression(PLS) analysis to predict moisture content(MC) of Korean pine wood samples.The NIR spectra were pretreated with the first and the second derivatives.MC prediction models for Korean pine wood were developed based on the original NIR spectra,the first derivated NIR spectra and the second derivated NIR spectra at seven varied wave lengths.The optimal model was shown b... |
