By adopting this method the formation of form belongs to a deposition of metallic atomic level, so that it can formroughness-free opening.
由于采用了这种方法,模板的成形是属于金属原子级的沉积,因而可形成无粗糙度的开口。

As roughness and form & position errors have an effect on evaluation result of cylinder diameters, it is necessary that roughness is filtered for evaluating cylinder diameters size.
Since if the frictional resistance coefficient is a function of relative roughness, then the form resistance coefficient is independent of the Reynolds number.
