摘　　要：根据热力学第二定律和非平衡热力学原理,推导出木材中由于热质传递引起的熵产的表达式。分析表明:在一般情况下,和单独的热质传递相比,由于热质传递的耦合作用引起的熵产可忽略不计。According to second thermodynamics law and ninequilibrium thermodynamics, expressions are derived for entropy generation due to heat and mass transfer processes in wood. The analysis shows that in general the entropy generation due to the coupling effect betwwen heat and mass transfer is negligible.
