However, the product has changed dramatically, from a single thickness of 6.8 mm to a range from sub-millimeter to 25 mm.
然而，玻璃制品在厚度上发生了巨大变化：从单一的6.8毫米变为亚毫米级至25毫米区间的任意厚度。

The problem of large curved surface measurement while it is erected was solved by this method with sub-millimeter precise, which was shown though some experiments.
实验表明这种方法解决了对架设状态下大曲面的检测问题，检测精度可达亚毫米级。
