The results also suggest that only wood particle with moisture content near fiber saturation point can reach the required final moisture content after one drying process, and ailflow temperature and flux can improve the drying capacity significantly.

气流温度和流量对提高系统的能力有明显的增强作用，它们是干燥能力改变的重要影响因素；在带载率增加的情况下，干燥后的终含水率略有增加，系统的去水能力随着带载率的提高几乎线性地相应提高。

In the process of wood drying, because that the dry rate on the surface of wood is ten times than which inside, the moisture content of wood on the surface reduce to the fiber saturation point first, and begin to shrinkage, but the moisture inside content of wood is far higher than the fiber saturation point, the higher the standard criterion in wood drying, the more obvious of shrinkage.

摘 要：在木材干燥过程中，由于木材表面水分的蒸发速度比木材内部水分移动的速度大10倍左右，因此木材表面的含水率首先降低到纤维饱和点，并开始发生干缩，而此时木材内部的含水率还远远高于纤维饱和点，干燥基准越硬，这种现象越突出，木材发生开裂的可能性就越大。

The results indicated that,during MV drying,moisture distribution in wood was relatively uniform,without an obvious moisture content gradient along the direction of thickness of wood.Moisture distribution in wood was more uniform in the last period of drying.Above Fiber Saturation Point,the movement of moisture through wood was assumed to be permeable movement of free water and vapor under the action of pressure gradient;below FSP,moisture existing in vapor form in wood moved in response to a pressure gradient.Moisture transfer caused by heat diffusion and a moisture content gradient could be neglected.

研究结果表明：在微波真空干燥过程中，木材内部的含水率分布比较均匀，在厚度方向没有明显的整体性含水率梯度，特别是在干燥的后期，木材内部的含水率分布更加均匀；当含水率在纤维饱和点以上时，木材中的自由水和水蒸气在压力梯度的作用下以渗透流的形式在木材内部迁移；当含水率在FSP以下时，木材中的水分在压力梯度的作用下以水蒸气的形式向木材表面迁移；因热扩散、含水率梯度引起的水分迁移可以忽略不计。

The moisture diffusion coefficient was increased at the early drying stage when the moisture content was high,and hit the maximum value when the moisture content drew close to the fiber saturation point,and then decreased gradually as the moisture content decreased.

结果表明：干燥温度越高，干燥各阶段水分扩散系数及平均水分扩散系数也越大；初始高含水率阶段，随含水率逐渐降低，水分扩散系数呈逐步增加趋势，在纤维饱和点附近时达最大值；随后，随含水率逐渐降低呈逐步减少趋势。
