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；
Otherwise the moisture content gradient and drying stress can be reduced by MW treatment when moisture content is below FSP.
当试材含水率降至FSP以下时，微波处理可以有效地减小木材内部的含水率偏差，从而减缓木材干燥应力。
For the exist of moisture content gradient and thermal gradient, the thickness swelling is larger than the line swelling and so the thickness swelling is the emphasis of study.
由于含水率梯度和温度梯度的存在，使得厚度膨胀远远高于线膨胀，因此厚度膨胀历来是尺寸稳定性的研究重点。
