Moisture transfer caused by heat diffusion and a moisture content gradient could be neglected.
因热扩散、含水率梯度引起的水分迁移可以忽略不计。
The reason is that it is under the effect of matrix potential gradient in stead of moisture content gradient.
其原因是土壤水运动是在相应的基质势梯度作用下发生的,而并不需要对应的含水量梯度。
However, a moisture content gradient occurred along the thickness direction but could be (balanced) after about a week.
干燥后板材的含水率在材堆内分布均匀,在板材厚度方向分布有一定差异,平衡后可以使用;
