During the drying process of MV, for the whole board, the effect of thermal diffusion on moisture movement is not significant, but it can cause a leveling of moisture profile in a local range of wood.

在微波真空干燥过程中，就整个板材而言，热扩散效应对木材中水分迁移的影响不大，但在局部的有限范围内，它对自动平衡木材内含水率具有显著的作用。

When various manipulations disturb the thermal boundary layer inside or the condensate film and gas-vapor diffusion layer outside, the heat transfer effect will be better or be worse off.

各种操作条件只有影响到管程的温度边界层或壳程的冷凝液膜层和气-汽扩散层，才能强化或恶化传热过程。
