气动测量是一种适喧性较广的精密测量。具有精度高,操作方便,不易受外界干扰,测量装置结构简单、制造容易、维护方便等特点,已经成为技术测量中不可缺少的一个分支。气动测量不仅适用于尺寸公差的测量,同样适用于形状和位置公差的测量。本文试就面的倾斜度误差的气动测量方法谈点粗浅的看法。一个平面处在空间的位置,可以由三坐标体系来表达。但当有一个理论正确平面作为特定的参考坐标 Pneumatic measurement is a more extensive and sophisticated measurement. With high precision, easy operation, less susceptible to external interference, measuring device structure is simple, easy to manufacture, easy maintenance and other characteristics, has become an indispensable technology measurement branch. Pneumatic measurement not only applies to the measurement of dimensional tolerances, the same applies to the measurement of shape and position tolerances. This article tries to talk about the sloppy view of the aerodynamic measurement method of the slope error. A plane in space position, can be expressed by the three coordinate system. But when there is a theoretically correct plane as a specific reference coordinate
