摘　　要：为探寻通风分配对主流烟气酮类化合物释放量的影响规律,采用两种色谱分离柱的GC-MS法测定了卷烟主流烟气中酮类化合物的释放量。结果表明:(1)定性定量共鉴别出56种酮类化合物,其中有27种酮类化合物的释放量>1μg·支^(-1),且其总量占56种酮类化合物释放总量的91%以上,表明这27种酮类成分是烟气中重要的酮类化合物。(2)滤嘴通风率和卷烟纸通风率与酮类化合物释放总量呈负相关关系,R^(2)大于0.98,且滤嘴通风率对酮类化合物释放总量的影响大于卷烟纸通风率。(3)卷烟纸总通风率与烟气中56种酮类化合物的释放量及其释放总量呈负相关关系。(4)在卷烟总通风率不变的前提下,随卷烟滤嘴通风率的增加,酮类化合物释放总量呈增加趋势;相同酮类化合物释放总量,可采用不同的滤嘴通风率和卷烟纸通风率的组合设计实现。In order to explore the effects of ventilation distribution on the releases of ketones in mainstream cigarette smoke,the releases of ketones in mainstream smoke were determined by GC-MS with two chromatography columns. The results showed that: 1) A total of 56 ketones were identified qualitatively and quantitatively. Among them,the releases of 27 ketones were more than 1 μg/cig,and their releases accounted for more than 91% of the total release of all 56 ketones,which suggested that these 27 ketones were important in mainstream cigarette smoke. 2) Both filter ventilation rate and cigarette paper ventilation rate negatively correlated to the total release of ketones in mainstream cigarette smoke with coefficients of determination(R;) more than 0.98, and the effect of filter ventilation rate was greater than that of cigarette paper ventilation rate. 3) The ventilation rate of cigarette paper negatively correlated to the releases of 56 ketones and their total release. 4) At the same total ventilation rate of cigarette,the total release of ketones increased with the increase of cigarette filter ventilation rate;and the same total release of ketones could be achieved by different combinations of filter ventilation rate and cigarette paper ventilation rate.
