在气垫导轨上测速度和加速度的新方法

A new method to measure speed and acceleration with air- cushion slideway

根据匀加速直线运动的特点，介绍一种测量速度和加速度的新方法，并导出测量公式。方法与原方法比较，测量简捷，而且精确度也得到提高。

This paper introduces a new method to measure speed and acceleration through experiments.The new method,after comparing the experimental results by the new method and by the traditional method,is found not only to be simple and easy,but can also improve the experiments to greater exactness.
