本文以多孔介质传热传质理论为基础，结合高频-对流联合加热干燥过程中热质传递的机理及特 性，通过质量、动量、能量守恒方程等建立了高频-对流联合加热干燥过程中锯材热质传递数学模型并给出相应定解条件。模型中每个自变量及因变量都有独立的控制方程，利用控制容积法建立相应控制方程的差分格式，将耦合偏微分方程按步骤解耦，以便于利用Matlab 或FORTRAN等编程求解时，达到每个自变量均可以独立求解的目的。

The research based on the theory of porous medium heat and mass transfer，combined with the mechanism and characteristics of heat mass transfer in radio-frequency and convective drying，establish the mathematical model and give the definite condition through mass momentum and energy conservation equations. Each independent and dependent variable has independent control equation. Use the finite volume method to establish difference equation for to decouple the coupled partial differential equations，so that each independent variable can be solved independently when programming in Matlab or FORTRAN .
