为更精确地拟合卷烟感官舒适性指标与部分烟气化学成分之间的关系，除传统的线性回归模型外，新引入3种非线性回归模型进行比较研究。同时，对检测的42种烟气化学成分采用逐步回归方法进行变量选择，以确定影响10个卷烟感官舒适性指标的关键烟气化学成分。研究结果表明：(i)模型拟合方面，在9个感官舒适性指标上非线性模型具有更好的预测性能，其中有3个指标非线性模型统计上显著优于线性模型；(ii)化学变量选择方面，苯甲酸、氨和巴豆醛等3个化学成分对感官舒适性存在负面影响，甲酸等14个化学成分对感官舒适性存在正面影响，羟基乙酸、亚油酸和游离烟碱等3个化学成分对不同的感官舒适性指标有正面或负面不同的影响。研究结果可为卷烟产品研发提供科学依据。

Three non-linear regression models were introduced to study relationship between cigarette sensory coziness and chemical composition in smoke. To identify 10 chemicals key to sensory coziness index, variable selection using stepwise regression method was performed with 42 measured chemicals. Results showed that (i) in terms of model fitting, non-linear models had better prediction performance than their linear counterparts on 9 sensory coziness indexes, among which 3 indexes boasted significant statistical supremacy on non-linear models;(ii) in terms of variable selection, 3 chemicals, namely benzoic acid, ammonia and crotonic aldehyde, had negative effects on sensory coziness, while 14 chemicals, such as formic acid, had positive effects, and other 3 chemicals, namely glycolic acid, linolic acid and free nicotine, had either positive or negative effects on different sensory coziness indexes. Such results can provide a theoretical foundation for developing cigarette products.
