The heating process of cured tobacco leaves will largely affect the final composition and content of gas products. The knowledge of the instant thermophysical properties of an individual tobacco leaf are important and necessary for deep understanding and further predicting the process. In this work, the thermal conductivity and volumetric heat capacity of a single tobacco leaf are simultaneously measured using an advanced transient electrothermal technique, in which the heating temperature can be well controlled by simply adjusting the feeding current. The measured thermal conductivities and volumetric heat capacities at different temperatures in the beginning stage of heating shows that the thermal conductivity of a single tobacco leaf decreases against the temperature and dominate the heat transfer process in the tobacco leaves, while the volumetric heat capacity is almost constant in the low temperature range.

烤烟叶的加热过程将在很大程度上影响气体产品的最终成分和含量。了解单个烟叶的即时热物理特性对于深入理解和进一步预测该过​​程非常重要和必要。在这项工作中，使用先进的瞬态电热技术同时测量单个烟叶的热导率和体积热容，其中通过简单地调节馈电电流可以很好地控制加热温度。加热开始阶段在不同温度下测得的热导率和体积热容表明，单片烟叶的热导率随温度的升高而降低，在烟叶内的传热过程中占主导地位，
