摘要:制备了不同卷烟纸透气度、定量、助燃剂钾钠比、麻浆含量、助燃剂含量及灰分含量的滤嘴无通风中支卷烟，对其逐口通风率进行测定。结果表明，卷烟纸透气度对中支卷烟静态通风率影响较大，呈正相关关系，麻浆含量和助燃剂钾钠比对卷烟纸通风率有一定影响，卷烟纸定量、助燃剂含量、灰分含量对卷烟纸通风率影响较小。中支卷烟第2口的通风率高于静态通风率，随着抽吸的进行，不同卷烟纸参数的卷烟，其逐口通风率递减5%左右。随着卷烟纸透气度的增大，抽吸时逐口间通风率相差值明显增大。

Abstract:Medium-sized cigarettes without filter ventilation with different cigarette paper air permeability， weight， potassium-sodium ratio of combustion enhancer， hemp pulp content， combustion enhancer content and ash content were prepared and the puff by puff ventilation rates of each cigarette were measured. The results showed that air permeability of cigarette paper had a large impact on the static ventilation rate of medium-sized cigarette， which was positively correlated， and hemp pulp content， potassium-sodium ratio of combustion enhancer had a certain effect on ventilation rate of cigarette， and weight of cigarette paper， combustion enhancer content， and ash content had little effect on the static ventilation rate of cigarette. The ventilation rate of the second puff of medium-sized cigarette was higher than the static ventilation rate. As smoking progressed， the puff by puff ventilation rate decreased by about 5% for cigarette with different cigarette paper parameter. As the air permeability of cigarette paper increased， the difference in ventilation rate between puffs increased significantly.
