AF M形貌分析表明陶瓷支撑体上的二氧化硅薄膜连续，膜表面较光滑、平整。
AFM image shows that the silica membrane on the ceramic support is continuous and the surface is relatively even and smooth.
另一个问题：在一般情况下，更严格的公差，两维地，并且在表面光滑度，较昂贵的打印机。
Another problem: in general, the tighter the tolerances, both dimensionally, and in surface smoothness, the more expensive the printer.
飞秒激光切削的角膜表面较徒手剥离的角膜表面光滑。
Cutting surfaces with laser was more smooth than that of manually made.
