抽吸间隔时间对卷烟焦油释放量的影响

进行了抽吸间隔时间的长短对卷烟抽吸口数、烟气焦油、烟碱和CO释放量的影响实验。抽吸间隔时间分别设置为 30、4 0、5 0、6 0、70、80、90和 10 0s ,测定了 2种牌号的卷烟。结果表明 :①抽吸间隔时间越短 ,每支卷烟的抽吸口数、焦油、烟碱和CO量越大 ,这与国外的研究结果比较一致 ;②无论抽吸间隔时间长短 ,每口烟气的焦油、烟碱和CO等化学物质的量基本上保持不变

Influence of Puffing Interval on Tar Delivery of Cigarette Smoke

The variation of puff number and tar, nicotine, and CO deliveries of cigarette smoke with puffing interval was tested. The puffing interval was 30, 40, 50, 60, 70, 80, 90, and 100 seconds respectively. Two brands of cigarette were determined. The results showed that 1) the puff numbers and tar, nicotine, and CO deliveries of cigarette smoke were increased with the decrease of puffing interval, and 2) the tar, nicotine, and CO deliveries per puff cigarette smoke were almost constant with the change of puffing interval. It was concluded that puffing interval could directly influence the puff number and tar, nicotine, and CO deliveries of cigarette, but its effects on the tar, nicotine, and CO deliveries per puff cigarette smoke were negligible.
