(1) The measurement datum of straightness error can be chosen arbitrarily, and the evaluation datum should conform to the principle of minimum condition. That is to say, when measuring the accuracy of the guideway, the actual outline of the guideway must contain two parallel ideal lines and minimize the distance height between the ideal lines. The distance between the two ideal lines is called the inclusive line of the guideway, which is the straightness error of the measured guideway.

　　(2)无论评价基准如何转换，发明奖的计量方向不变的原则。这一原则是反映在测量方向测量读数应该垂直于测量基准,使用坐标测量,包含两行之间的距离不应由于评估基准转换,导致小评价基准之间的倾斜和改变方向。

　　(2) No matter how the evaluation benchmark is changed, the measurement direction of the invention award remains unchanged. This principle is reflected in the measurement direction reading should be perpendicular to the measurement datum. Using coordinate measurement, the distance between two rows should not lead to the tilt and direction change between small evaluation datum due to the conversion of evaluation datum.

　　(3)导轨后只用几个相同音高的齿轮,其支持点端到端连接的帮助下一个特殊的桥梁板或其他精密角度测量仪,并沿着测量方向,分别测量倾角的零位选中每个齿轮相对于级别(测量基准是水平线)。这可以转换为相邻高度之间的差值。等间距有限点相对高差的综合结果反映了被测导轨的曲线起伏。

　　(3) Only a few gears of the same pitch are used behind the guide rail, which supports end-to-end connection of points to help the next special bridge plate or other precision angle measuring instrument, and along the measuring direction, the zero position for measuring the inclination angle is selected for each gear relative to the level (the measuring datum is a horizontal line). This can be converted to the difference between adjacent heights. The comprehensive results of relative height difference between finite points with equal spacing reflect the curve fluctuation of the guideway under test.
