Surface roughness, often shortened to roughness, is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form.
surface roughnessとは意味:仕上げ面の粗さ、表面粗さ、表面粗度 surface roughness meaning:[Engineering] The closely spaced unevenness of a solid surface (pits and projections) that results in friction for solid-solid movement or for fluid flow across the solid surface.surface roughness перевод:шероховатость поверхности
