摘  要:
本文利用电子鼻检测仅知生产日期的天然苹果香精样品,并对所获数据进行PCA及DFA分析,结果表明:生产日期与产品质量有着密切的联系,其中牟平总公司样品以2004年10月31日为界分为两大组群,白水分公司2005年的样品明显区别于2004年的样品。

摘  要:
In this paper,the natural apple essence samples known only for the production date were identified by using electronic nose. Then, the acquired data were analyzed by principal component analysis(PCA) and discriminant factor analysis(DFA). The results indicated: the product quality is closely related to its production date. The samples of Mouping Corporation were divided into two groups with Oct 31, 2004, and Baishui Corporation samples of the year 2005 can be obviously differentiated from samples of the year 2004.
