摘要
为了分析云南烤烟化学成分与烟气成分的相互关系,采集了586个云南烤烟样品的22个化学成分和4个烟气成分,在MATLAB 5.0平台下,以22个化学成分构建的275个交互项数值为自变量,烟气成分数值为因变量,建立二次多项式逐步回归模型。模型分析结果显示,烟叶中的燃烧性成分与烟气成分呈显著相关关系;烟气总粒相物、焦油及烟碱量与烟叶中的碱性成分呈显著相关关系。
To investigate the relationship between chemical components and cigarette gas components of flue-cured tobacco in Yunnan province,4 chemical components in cigarette gas and 22 chemical components in tobacco leaves of 586 flue-cured tobacco leaf samples collected from Yunnan tobacco-growing area were studied.According to the data of the chemical and cigarette gas components of 586 samples,275 interaction values which are constructed by the 22 chemical indices used as independent variables and smoke index value used as the dependent variable in the MATLAB 5.0 platform.The model of smoke gas components and chemical components of tobacco leaves was established by quadratic polynomial stepwise regression.The result showed that there was significance correlation between combustible components of flue-cured tobacco leaves and smoke components,and there were significant correlations between TPM,Tar,nicotine of smoke and alkaline chemical compositions.
