The surface shall be containedbetween two parallel planes 0.1 apart and perpendicular to the datum axis A.
表面必须处在与基准轴线A垂直的两个相距0.1的平行平面之间。
By using this method, not only overelaborate drawing and hand-calculating can be avoided, but also the flatness of four kinds of datum-planes can be assessed quickly and precisely.
此法可避免频琐的作图和手工计算，迅速、准确地对四种基准平面的平面度进行评定。
