摘　　要：在吸烟机上,研究了不同抽吸条件下,卷烟主流烟气中苯并[a]芘以及TPM、烟碱和CO释放量的差异。研究表明减少烟蒂长度、提高抽吸频率、增加抽吸容量均能引起主流烟气苯并[a]芘以及其他有害物质释放量的增加,但并不呈线性。某一抽吸参数的变化,对主流烟气苯并[a]芘释放量的影响最小,对烟碱的影响最大。但相对于标准抽吸条件,如果减少烟蒂长度、高频率、高容量这其中的任何2种或3种吸烟方式同时采用,主流烟气中苯并[a]芘释放量的增加幅度却大于烟碱。The difference of deliveries of Benzo[a]pyrene, TPM, nicotine, and CO in mainstream smoke was studied with alternative puffing regime using smoking machine. Results showed that decreasing butt length, increasing puffing volume and shortening puffing alternation can all increase yield of BaP, TPM, nicotine and CO in mainstream smoke. However, no linear relationship was found. Effect of changing a certain puffing parameter on the delivery of nicotine is greater than on that of BaP, but the conclusion would be reverse if two or three puffing parameters were altered simultaneously.
