摘　　要：随机抽取20副眼镜架和太阳镜,在不同测量时间点(立即测量、30 min、60 min、120 min)测量镜腿两腿间距离,进而计算永久变形量数值,运用单因素方差分析比较不同测量时间点的永久变形量计算结果,表明当永久变形量小于5 mm时,测量时间点不影响永久变形量。20 spectacle frames and sunglasses were chosen randomly. Distance between the sides were measured at different test time(immediately, after 30 min, after 60 min and after 120 min), then permanent deformation values were calculated. Analysis of variance method was applied to compare the permanent deformation values rising from different test time. Results that the permanent deformation values were independent of different test time when the values were not more than 5 mm were obtained.
