The regularity of dimensionalchange of Xuan paper was studied, and the reasons of dimensional unstability were discussed.
通过对不同条件下干燥方法对宣纸形变影响的研究，对纸张变形的原因进行了探讨。
2
Take the mean value of dimensionalchange rate of the 3 test pieces in longitudinal or transverse directions as the test result.
分别计算3块试件纵向或横向的尺寸变化率的平均值作为纵向或横向试验结果。

The results show that the weldments made from those metals in as-welded condition are instable in dimension and the rate of dimensionalchange decreases with time.
