| 摘 要： | 推导出了烟草导热系数与湿基含水率的关系式，并用实验测定值检测了推算式的精度。对于烟叶堆积床，推算值与实验测定值的绝对平均偏差为1．75％，算术平均偏差为0．15％；对于烟丝堆积床，推算值与实验测度值的绝对平均偏差为2．36％，算术平均偏差为0．25％。其精度均满足工程需求。该关系式也可推广应用于其他含湿多孔介质导热系数的计算。

| Abstract: | The relation ship between thermal conductivity and w ater content of tobacco is presented in this paper. The accuracy of the recommen ded formula is checked by experimental data. The calculated results agree very w ell with the experimental data. For leaf tobacco stack, the absolute average dev iation is 1.75%,and the arithmetic average deviation is 0.15%, while for cut tobacco as compared with 2.36% and 0.25%, respectively, for cut tobacco. The for mula can be also used to calculate other porous material. |
