| 摘 要： | 从木材的化学组成和微观结构出发,应用统计热力学原理和类比推理方法,从理论上研究和推导木材弦向导温系数的理论表达式。应用该表达式计算28种木材的弦向导温系数,并与同条件下的试验值相比较,理论计算的最大误差为12.9%,平均误差为8.3%。

| Abstract: | The theoretical expression of wood thermal diffusivity in tangential direction was derived by statistical thermodynamics and analogy from chemical elements and microstructure of wood.Theoretical values of wood thermal diffusivity in tangential direction were calculated with the derived expression for 28 tree species.The maximum deviation is 12.9% and average deviation is 8.3% are found between existing experimental values and theoretical ones for the investigated species under the same condition as this wor... |
