In order to study the delivery behavior of ammonia and its correlation with routine analytes in mainstream cigarette smoke, including tar, nicotine and moisture content, 8 cigarette samples of different specifications and price categories were tested. The contents of ammonia, tar, nicotine and moisture content in particulate matters were determined respectively puff-by-puff; and the correlation of ammonia with tar, nicotine and moisture deliveries was analyzed. The multiple linear regression equation was developed. The results showed that: 1) Ammonia delivery increased linearly puff by puff, which was extremely significantly positively correlated to the contents of tar and nicotine and negatively correlated to moisture content. 2) The developed regression equation fitted pretty well.%为了解卷烟在逐口抽吸过程中氨的释放特性以及氨与常规烟气检测成分焦油、烟碱、水分的相关性,选取8种不同规格不同档次的卷烟,逐口测定了烟气粒相物中氨和常规烟气检测成分焦油、烟碱以及水分的含量,分析了卷烟在逐口抽吸过程中氨的释放特性以及氨与烟气焦油、烟碱、水分的相关性,并建立了以焦油、烟碱、水分为自变量的氨释放量多元线性回归方程.结果表明:卷烟主流烟气中氨的释放量逐口线性增加；氨与烟气焦油量及烟碱量呈极显著正相关,氨与烟气水分呈负相关；建立的数学回归模型拟合效果较好.
