摘　　要：为阐明滤嘴对卷烟主流烟气不同成分逐口释放趋势的影响规律,比较了滤嘴卷烟和无滤嘴卷烟63种烟气成分的逐口释放量,通过记录滤嘴卷烟在不同抽吸口数序号时燃烧线的位置,在未抽吸卷烟的对应位置处划线,测定了卷烟阴燃至不同划线位置的烟气成分单口滤嘴截留率,分析了滤嘴截留对卷烟烟气成分逐口释放趋势的影响特征。结果表明:①滤嘴卷烟烟气成分逐口释放趋势与沸点相关,随抽吸口数序号增加主要呈现出低沸点成分的释放量持续增加、中沸点成分的释放量先增加后降低、高沸点成分的释放量先增加后趋于稳定3种趋势。②无滤嘴卷烟烟气成分逐口释放量随抽吸口数序号增加均呈增加趋势。③滤嘴截留率随烟支变短呈增加趋势,不同烟气成分的逐口释放趋势主要取决于其逐口滤嘴截留率的变化幅度。To investigate the effects of filter on the puff-by-puff release trends of different chemical components in mainstream cigarette smoke,the puff-by-puff releases of 63 smoke components from cigarettes with or without cellulose acetate filters were compared by recording the positions of the burn line for different puff numbers on filtered cigarettes and marking at the corresponding positions of the unlit cigarettes.The individual puff filtration efficiencies of filtered cigarettes for smoke components were determined by allowing the cigarette to smolder to the marked positions,and the effects of filter filtration on the puff-by-puff release trends of cigarette smoke components were analyzed.The results showed that:1)The puff-by-puff release of smoke components of filtered cigarettes were related to the boiling points of the smoke components.With increasing puff number,there were three main releasing trends,namely,the components with lower boiling points were released continuously,those with medium boiling points were first increased and then decreased,and those with higher boiling points first increased and then stabilized.2)The puff-by-puff releases of the smoke components of the unfiltered cigarettes all showed an increasing trend as the puff number increased.3)Filter’s filtration efficiencies increased with cigarette rod shortening during smoking,the difference in the puff-by-puff release trends for different classes of smoke components mainly depended on the magnitude of changes of filter filtration efficiencies.
