The stress produced during the process of drying had a certain relation with moisture gradient, shrinkage, moisture and stress index.
干燥过程中产生的应力与含水率梯度、干缩量和含水率、应力指标，存在一定的相关关系。
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。
Temperature gradient promotes transfer of moisture in larch lumbers, but should form and maintain long time temperature gradient to accelerate drying rate through proper schedule;
温度梯度可以促进木材内部水分的传递，但应通过采取适当的工艺形成并维持较长时间的温度梯度来加快干燥速度；
Polyurethane organic precursors with different pore siize were dipped in slip, then super posited them together and the gradient porous ceramics were made by drying and firing.
将不同孔径的聚氨酯泡沫前驱体分别浸渍泥浆，再以一定的方法将其叠放在一起经过干燥、烧成等工艺可以制得具有一定强度的孔梯度多孔陶瓷。
