摘要
在对空间变量进行变换的基础上,引入木材等效导热系数及其与弦向、径向、顺纹3个主导热系数之间的数量关系,简化了各向异性木材中热传导的非稳态偏微分方程;再应用数学物理方法求解各向异性木材传热过程中温度场时空分布的解析解.
The time-dependent partial differential equation of the heat transfer in anisotropic wood was simplified when a equivalent thermal conductivity of wood was introduced and the quantity relation between equivalent thermal conductivity and three principal conductivity of anisotropic wood was set up on the basis of space variable transformations.The analytic function of the temperature field from heat transfer in anisotropic wood was solved by means of the methods of mathematical physics.
