为考察加热状态下烟叶的烟气释放特征，利用实验室加热装置对烤烟（B2F、C3F）、白肋烟（B2F、C3F）及香料烟（B1、B2）3种类型烟叶在200~400℃进行加热，并测试烟气粒相物、烟碱、水分和焦油的释放量。结果表明：①在加热状态下，不同类型及部位烟叶的烟气释放具有相似的变化趋势，粒相物、烟碱、水分及焦油的释放量均随加热温度升高而逐渐增加；②当加热温度高于250℃，烟叶的烟气烟碱释放比例显著高于烟叶的游离烟碱比例，释放烟碱不仅来自烟叶自身游离烟碱的迁移，还包括烟叶中结合态烟碱的热解释放；③烟叶在加热状态下的烟气水分释放量很高，释放水分不仅来自烟叶自身水分的迁移，还有相当部分的水分来自烟叶的热解过程。

In order to investigate the smoke release characteristics of tobacco under heating, flue-cured (B2F and C3F), burley (B2F and C3F) and oriental (B1 and B2) tobaccos were heated in a laboratory heating device at 200-400 ℃, and the deliveries of TPM, nicotine, moisture and tar in smoke were analyzed. The results showed that: 1) Under heating status, the tobacco leaves of different kinds and stalk positions presented similar trends, the deliveries of TPM, nicotine, moisture and tar increased gradually with a rise in heating temperature. 2) When the heating temperature was higher than 250 ℃, the nicotine release ratio in smoke was significantly higher than the free nicotine ratio in corresponding tobacco leaf, it suggested that the nicotine in smoke was not only from the migration of free nicotine but also from the thermal decomposition of bound nicotine in tobacco. 3) The higher moisture level in the smoke of heated tobacco, was not only from the migration of moisture in leaf but also from the pyrolysis of tobacco.
