摘要：

A two-dimensional unsteady mathematic model about heat transfer of wood veneer mat during hot pressing was built according to the energy balance equation. This model describes the temperature variation of a wood with locations and times during hot pressing. The visual numerical solution was obtained by using the PDE tool of MATLAB and the calculated results were verified by experiments. A comparison was made between the calculated temperature curve and the measured temperature curve. The comparison shows that this model is suited for simulating heat transfer of a wood mat and the simulated results can be used to guide of the production of wood-based composites.
