本文对在气垫导轨上所做的模拟匀速直线运动、加速度的测量等实验中误差产生的原因及减小误差的方法进行了讨论,得出如下两个结论:1、模拟匀速运动时取滑块滑行速度以不小于0.6m/s为宜;2、测量加速度的两种方法中,在倾斜导轨上测量比在水平导轨上用吊码的测量误差要小。 This paper discusses the causes of errors and the methods to reduce the error in experiments such as simulating uniform linear motion and acceleration measurement on air cushion guideway, and draws the following two conclusions: 1. When simulating the uniform motion, take the slider Slip speed of not less than 0.6m / s is appropriate; 2, the two methods of measuring acceleration, the measurement on the inclined rail than the hanging rope in the horizontal rail measurement error is smaller.
