聚类分析在卷烟配方中的应用

The Application of Cluster Anlysis on Cigarette Blending

为研究卷烟配方中叶组配方的等级替代问题,对豫中豫南不同等级烟叶36个样品的常规化学成分及营养元素、烟气成分和感官质量评吸指标进行了聚类分析,利用统计分析软件SPSS11.0提供的方法进行层次聚类法,根据结果确定其在配方中的用途。结果表明,(1)大多数样本的品质指标存在相似性,少数样本则存在较大的差异;(2)属于同一类群样本的品质指标差异较小,属于不同类群样本的品质指标差异较大;(3)进行卷烟配方时,当需要的某一等级原料不足或缺乏时,可根据烟叶质量的相似性,从相同的类群中寻找。

In order to find out a method on substitute of different grades , we analysised the different grades tobacco of middle and southern of Henan province, including routine chemical components, smoke components and smoking quality. And then use the statistic analysis software SPSS11.0 to defined the usibility of these tobacco leaf in prescription. The result showed： （1） most of the samples have the comparability, only little of these samples exist obvious difference, （2） the quality index in a group have little diference,otherwise difference is obvious.（3） in the process of prescription, we can use the quality simility to find the substitute when a kind of tobacco leaf in prescription is limited or absence.
