摘　　要：卷烟主流烟气粒相经二氯甲烷浸提,进行GC/MS分析,对通风稀释、加长滤嘴后卷烟主流烟气粒相45种挥发性、半挥发性中性成分的变化进行了分析研究。通风稀释20%卷烟、25mm滤棒卷烟与参比卷烟(20mm滤棒)相比,45种中性成分总量分别减少了19.0%、30.7%。通风稀释、加长滤嘴后卷烟主流烟气不同中性成分减少的程度不同,分子量较小、沸点较低的物质减少较多,而分子量较大、沸点较高的物质减少较少。Effects of ventilation dilution and longer filter on 45 volatile and semi-volatile neutral components of mainstream cigarette smoke particulate were studied by GC/MS analysis after the dichloromethane extract of smoke particulate. Results showed that the total amount of 45 semi-volatile neutral components from cigarette with 20% ventilation and 25 mm filter were reduced by 19.0% and 30.7 % compared with a reference cigarette with no ventilation and 20 mm filter, respectively. However, the degree of reduction of each component was different. Neutral components of less molecular weight and lower boiling point dropped more than those of greater molecular weight and higher boiling point.
