(1)直线度误差测量基准可任意选择，评价基准应符合较小条件原则。也就是说，在测量导轨的精度时，被测导轨的实际轮廓必须包含两条平行的理想线，并使理想线之间的距离高度较小化。两理想线之间的距离称为导轨包含线，即被测导轨的直线度误差。

(1) The measurement datum of straightness error can be selected at will, and the evaluation datum should conform to the principle of smaller condition. In other words, when measuring the accuracy of the guide rail, the actual contour of the measured guide rail must contain two parallel ideal lines, and the distance between the ideal lines must be reduced. The distance between two ideal lines is called guide inclusion line, which is the straightness error of the measured guide.

(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 changes, the measurement direction of the invention award will remain unchanged. This principle is reflected in the measurement direction, the measurement reading should be perpendicular to the measurement datum, the use of coordinate measurement, including the distance between two lines, should not be due to the conversion of the evaluation datum, resulting in the tilt and change of direction between the small 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 with the same pitch are used behind the guide rail. With the help of the end-to-end connection of their supporting points, a special bridge plate or other precision angle measuring instrument is set up. Along the measuring direction, the zero position of the inclination angle is measured respectively, and each gear relative to the level is selected (the measuring datum is the horizontal line). This can be converted to the difference between adjacent heights. The synthetic result of relative height difference of equidistant finite points reflects the curve fluctuation of the measured guide rail.
