摘　　要：为明确滤嘴通风对卷烟主流烟气成分释放的影响,采用GC-MS方法分析了不同圆周卷烟样品中主流烟气气相和粒相成分的分布,考察了不同滤嘴通风率对卷烟样品主流烟气成分释放的影响。结果表明:①随着滤嘴通风率的升高,主流烟气气粒相共存成分中气相占比呈逐渐升高的趋势。②滤嘴通风后,主流烟气中气相和粒相烟气成分释放量的降幅与其沸点之间呈较强负相关关系,粒相成分释放量的降幅明显高于气相。③纯气相成分、气粒相共存成分释放量的平均降幅高于焦油,纯粒相成分释放量的平均降幅低于焦油。滤嘴通风率越高,常规卷烟主流烟气中纯气相、气粒相共存及纯粒相成分释放量的降幅均越大。滤嘴通风会引起主流烟气中不同香味成分比例的变化。④随着烟气成分沸点的升高,滤嘴通风后不同圆周卷烟烟气成分释放量的降幅均呈先减小后增大再减小的变化趋势。滤嘴通风率相近条件下,随着卷烟圆周的减小,较高沸点烟气成分释放量的降幅与焦油释放量的降幅之间的差异更为显著。To clarify the effects of filter ventilation on the releases of chemical components in mainstream cigarette smoke,a GC-MS method was used to analyze the distributions of gas and particulate phase components in mainstream smoke from cigarette samples of different circumferences.The effects of filter ventilation rate on the releases of mainstream smoke components from the cigarette samples were investigated.The results showed that:1)The proportion of gas phase components in the coexisting gas and particulate phase components in mainstream smoke gradually increased with increasing filter ventilation rate.2)There was a strong negative correlation between the reduction in the releases of the gas and particulate phase components and their boiling points,and the reduction in the releases of the particulate phase components were generally higher than those of the gas phase components in the mainstream smoke of the filter-ventilated cigarettes.3)The average reduction in the releases of the gas phase components and coexisting gas and particulate phase components was higher than tar,while the average reduction in the releases of the particulate phase components was lower than that of tar.For the conventional cigarettes,the reduction in the releases of the gas phase components,coexisting gas and particulate phase components,and the particulate phase components increased with increasing filter ventilation rate.The proportions of different aroma components in mainstream cigarette smoke varied with filter ventilation.4)As the boiling points of smoke components increased,the reduction in the releases of smoke components from cigarettes of different circumferences with filter ventilation first decreased,then increased,and finally decreased again.Under similar filter ventilation rates,the reduction in the releases of smoke components with higher boiling points differed more significantly from that of tar with decreasing cigarette circumference.
