节距法是应用水平仪或自准直仪,在被测面上选择一定的测量截面(俗称布线),且在这些截面上按照规定的测点(俗称布点)测出数据,通过数据处理求取平面度误差的一种测量方法。所谓数据处理,是将各基准产生的各测量截面离散点的数据,用评定原则联系起来,统一在一个基准面上,获得连续表面的平面
Pitch method is the use of a level or self-collimator on the measured surface to select a certain measurement cross-section (commonly known as wiring), and in these sections in accordance with the provisions of the measuring point (commonly known as cloth point) measured data obtained by data processing A method of measuring flatness error. The so-called data processing, is the reference points generated by the measurement of each discrete data points cross-section, linked with the assessment principle, unified in a reference surface to obtain a continuous surface of the plane
