摘要: 从木材的微观结构出发,应用物理力学的基本原理,建立木材比热的理论表达式.对27种不同树种的木材,在不同含水率、不同温度下,比热的理论值与相同条件下的实验值相比较,最大误差不超过11%,平均误差在5%以内.

关键词: 木材比热, 理论表达式

Abstract: In this paper, the theoretical expression of the specific heat of wood is set up from the microstructure of wood and by applying some basic principles of physicomechanics. when the theoretical values of specific heat of 27 different species of wood with different moisture contents and temperatures are compared with the experimental values in the same conditions, it has been discovered that the maximum error is less than 11%, and the average error is within 5%.

Key words: specific heat of wood, theoretical expression
