摘　　要：为研究打孔通风在加热卷烟中的作用,制备了在烟支降温段通风率为0、15%、25%、35%的4个通风梯度的加热卷烟,分析了不同通风率样品的气溶胶温度变化及烟碱和甘油的转移行为。结果表明:①在0到35%的通风率范围内,气溶胶最高温度和平均温度与卷烟通风率线性负相关,且前4口气溶胶的温度随通风率增加下降趋势较明显。②随通风率增加,滤嘴段的烟碱截留率非线性下降,烟芯段的烟碱残留率非线性上升。通风率由0升高至25%,气溶胶烟碱转移率非线性上升,在通风率为25%~30%之间存在一个拟合最大值,其后呈下降趋势。③随通风率增加,滤嘴段的甘油截留率非线性下降,降温段的甘油截留率略有下降,烟芯段的甘油残留率、气溶胶甘油转移率均非线性上升。④降温段通风能提高烟碱和甘油气溶胶转移率,其直接原因是增大通风率能降低烟碱和甘油的截留率。To study the effect of perforated ventilation in heated tobacco products,tobacco stick samples were prepared at four ventilation rates(0,15%,25%and 35%)in the cooling section.Aerosol temperature and the transfer behavior of nicotine and glycerol were analyzed.The results showed that:1)Within 0 to 35%ventilation rates,there were linear negative correlations between the maximum and average aerosol temperatures and the ventilation rate.The aerosol temperatures of the first four puffs showed a distinct downward trend with increasing ventilation rates.2)As the ventilation rate increased,the retention rate of nicotine in the filter section decreased non-linearly,while the residual nicotine in the tobacco section increased non-linearly.As the ventilation rate increased from 0 to 25%,the transfer rate of nicotine in aerosol showed a nonlinear increasing trend.There was a maximum fitting value for the transfer rate of nicotine in aerosol between 25%and 30%ventilation rate,then it decreased.3)As the ventilation rate increased,the retention rate of glycerol in the filter section decreased non-linearly and that in the cooling section decreased slightly,and the residual rate of glycerol in the tobacco section and the transfer rate of glycerol in the aerosol increased non-linearly.4)Ventilation in the cooling section could increase the transfer rates of nicotine and glycerol in the aerosol by reducing their retention rates.
