| 摘 要： | 用锥型量热计研究了三种烟叶在暴露于不同辐射热通量下的燃烧特性。实验结果表明，在较低的辐射热通量下，烟叶的燃烧过程主要是以阴燃为主，；在较高的热通量下，烟叶先发生着火燃烧，再转为阴燃。

| Abstract: | The combustion characteristics of three kinds of tobacco leaf have been studied using the Cone Calorimeter at three heat fluxes,i.e.10kW/m\ 2,20kW/m\ 2and 30kW/m\ 2.The results show that at lower heat fluxes the combustion of tobacco is characterized as smouldering. At higher heat flues e.g. more than 20kW/m\ 2,the tobacco become ignited first, then flame extinguishes itself a few seconds later (after ignition) and the combustion is converted into smouldering. |
