| 摘 要： | 不同产地和采收期的同种中药材在感官上很难区分.提出一种在自然态下采用PEN3电子鼻鉴别不同产地和采收期中药材的方法.首先通过电子鼻获取样本的气味信息,综合气味信息各方面的特征组成一个特征集合,采用逆向反馈方法提取特征,获得最能区别样品的特征子集,利用PCA+LDA算法对样本进行分类,最后运用欧式距离、马氏距离对未知样本...

| Abstract: | It is difficult to distinguish the same kind of Chinese herbal medicines(CHMs)with different growing areas and harvesting dates.An electronic nose(E-nose)PEN3 was used to discriminate the CHMs with different growing areas and harvesting dates under natural state.Firstly,odor information of samples was obtained by E-nose,and feature set was constituted by all aspects of the representative characteristics of odor information.Then,negative feedback was applied to extract features,and the most effective feature... |
