摘要
提出声子是木材中热传导的能量运载者．应用物理力学的原理和方法，推导出木材径向导热系数的理论表达式．应用该表达式计算了１８ 种木材径向导热系数，最大误差为１３．７％ ，平均误差为５．３％ ．
It is suggested that the phonon is the carrier of the transmission of thermal energy in wood in this paper. The theoretical expression of the thermal conductivity of wood in the radial direction is developed on the basic principles of the physical mecha nics. Then, the thermal conductivity of 18 species of trees can be calculated by the formula with the maximum relative error 13.7%, the average relative error 5.3%. Compared with the experimental value in the same condition, the calculation result is satisfactory.
