| 摘 要： | 目的]研究不同风格及产地的卷烟。方法]样品原始近红外光谱分别经过最小-最大归一化、一阶导数、一阶导数＋矢量归一化、一阶导数＋最小-最大归一化、二阶导数和连续小波变换（CWT）等方法处理后进行了主成分分析（PCA）,建立了以马氏距离为基础的卷烟识别模型。结果]小波变换模型有更好的样品识别能力,模型校正集样品的识别率为96.9%,检验集样品识别率为100%.分类可视化结果表明样品对本类型卷烟风格特征的表达最突出,国内烤烟型卷烟的国外混合型特征最不明显,国外混合型卷烟的国内烤烟型特征最不明显,国外烤烟型卷烟的国外混合型特征最不明显。结论]采用近红外光谱技术可对不同风格及产地的卷烟进行正确识别。
