摘要/Abstract

摘要： 根据木材的细胞结构,从导热与导电宏观规律的相似性出发,应用类比推理方法推导出木材径向热导率的理论计算公式。应用该公式计算20种木材的径向热导率,并与同条件下的实验值进行了比较。理论值的最大误差为12.4%,平均误差在5%以内。

关键词: 木材, 类比推理, 热导率

Abstract: The theoretical formula of wood's radial thermal conductivity was derived through anal-ogism in accordance with the cell structure and thermal conductivity of the wood. With the formula derived, the theoretical values of thermal conductivity of 20 species of trees were calculated and comparison was also made with the experimental values under the same conditions. The resultsand average error 4.9%.

Key words: thermal conductivity, analogism, wood
