为研究卷烟燃烧状态对巴豆醛主流烟气释放量及转移分布的影响，通过改变卷烟纸透气度调控卷烟裂解/蒸馏状态，考察了卷烟样品燃吸时巴豆醛逐口主流烟气释放量、滤嘴截留量、燃烧锥中残留量及其在卷烟不同部位的分布规律。结果表明：①随着抽吸口序的增加，主流烟气中巴豆醛释放量总体上呈上升趋势，但与燃烧锥中巴豆醛残留量无明显相关性；②卷烟逐口燃烧所产生巴豆醛的主流烟气转移率为36%~48%，滤嘴截留率为12%~34%，燃烧锥中残留率为16%~27%，烟丝吸附率低于13%；③卷烟逐口主流烟气中巴豆醛的释放量与卷烟纸透气度无相关性。“,”In order to investigate the effects of cigarette combustion status on the delivery, transfer and distribution of crotonaldehyde in mainstream cigarette smoke, the delivery in mainstream cigarette smoke, retention by filter, residue in combustion cone and distribution among different cigarette parts of crotonaldehyde were studied on a puff-by-puff basis by adjusting cigarette pyrolysis/distillation status via changing the air permeability of cigarette paper. The results showed that: 1)With the puffing going on, the crotonaldehyde delivery in mainstream cigarette smoke increased in general, whereas it did not obviously correlate to the residue of crotonaldehyde in combustion cone. 2)The rates of mainstream smoke transfer, filter retention, and residue in combustion cone of crotonaldehyde on a puff-by-puff basis were 36%-48%, 12%-34%, and 16%-27%, respectively. The adsorption rate of cut tobacco to crotonaldehyde was less than 13%. 3) There was no correlation between the puff-by-puff delivery of crotonaldehyde in mainstream cigarette smoke and the air permeability of cigarette paper.
