摘　　要：采用逐步判别分析法以卷烟烟丝化学指标为自变量对不同品牌的卷烟进行判别分析,构建判别函数,并对判别函数的判别效果进行检验。结果表明,总糖、pH值、总挥发碱、果糖、葡萄糖、蔗糖、马来酸、柠檬酸、油酸、己酸、辛酸、苯甲酸、癸酸、3-羟基-2-丁酮、2-羟基-3-甲基-2-环戊烯-1-酮、氧化异佛尔酮、金合欢基丙酮、寸拜醇等18个变量进入判别函数,由判别函数的方差分析可知判别函数具有显著意义;用自身验证法和交互检验法对原样品进行回判,回判准确率均为100%,新样品的判别准确率达到100%,判别效果良好。Stepwise discriminatory analysis of cut tobacco from different cigarette brands was carried out. A discriminant function was developed and verified. Result indicated that 18 variables, i.e.,total sugars, pH, total volatilealkali, fructose, glucose, saccharose, maleicacid, citricacid, oleic acid, caproicacid, caprylicacid, benzoicacid, capricacid, 3-hydroxy-2-buty- lone, 2-hydroxy-3-methyl-2-cyclopenten-l-one, keto-isophorone, farnesylacetone, thunbergol, were included in the discriminant function. ANOVA showed that the discriminant function was of high significance. The original samples were re-discriminated by using the methods of self and mutual test with a discrimination accuracy of 100% . The discrimination accuracy for new samples was up to 100% . The discriminant function had a very good effect in discrimination and hence merits recommendation for extension in actual application.
