| 摘 要： | 本文应用不可逆过程热力学研究木材干燥过程中的热质迁移现象，从中得到结论：木材中的湿度梯度和温度梯度在引起物质流的同时、产生热分子压力效应亦可引起热流的交叉作用．由此提示：在建立热流宏观规律时，应考虑热分子压力效应对热传导的影响

| Abstract: | The transport phenomena of the heat and that of the mass were studied in this paper by applying the thermodynamics of irreversible processes. The conclusion has been made that there is a cross transport phenomena in which a mass flux and a thermo molecular effect of pressure which produce a heat flux are produced by the gradient of the moisture and that of the temperature in wood. Influence of thermo molecular effect of pressure on heat transfer has to be considered to set up macroscopic law of the heat flux, therefore. |
