摘要
为分析烟丝分布对卷烟主流烟气中氨和焦油释放量的影响,使用相同的烟用材料卷制成3种卷烟,其烟丝在烟支两端的分布分别为前端密后端疏(A)、前后端均匀分布(B)和前端疏后端密(C);比较3种卷烟主流烟气中氨和焦油释放量的差异;并应用逐口抽吸分析3种卷烟氨和焦油释放量变化的原因。结果表明:①烟丝分布改变以后,卷烟的逐口抽吸也发生了变化,从而对主流烟气焦油和氨的释放量产生影响;②与对照B相比,A和C两种卷烟焦油和氨的释放量均有所降低;烟丝分布前端疏后端密的卷烟(C)主流烟气中氨和焦油的释放量均小于烟丝前端密后端疏分布的卷烟(A)。
In order to investigate the influence of cut rag distribution in cigarette on the deliveries of ammonia and tar in mainstream cigarette smoke (MCS), cigarette samples with different filling density at two ends (Sample A, higher filling density at the lit end and lower at the filter end of cigarette; Sample B, consistent filling density; Sample C, higher density at the filter end and lower at the lit end) were made with the same materials. The deliveries of ammonia and tar in MCS were compared and the results were discussed on a puff-by-puff basis. The results showed that: 1) Puff-by-puff smoke deliveries changed with the change of cut rag distribution, then affected the deliveries of ammonia and tar in MCS; 2) Comparing with the control, Sample B, the deliveries of ammonia and tar in MCS of Sample A and C reduced somewhat, and Sample C reduced more significantly.
