调平气轨的方法在各实验指导书中提出过几种,我们从工作中摸索出一种“双程动态法”,现介绍如下: 让滑块以一定的初速度由一端向另一端运动,再即刻以相等或接近的初速反向运动。若后光电门的计时总大于前光电门的计时(相差不大),则可认为气轨已调平。设气轨左侧略 The method of leveling the air track proposed in each experimental guide several, we work out a kind of “two-pass dynamic method”, are introduced as follows: The slider to a certain initial velocity from one end to the other end of the movement , And then immediately at an equal or close to the initial velocity of reverse motion. If the total time after the photoelectric door is greater than the timing of the front photoelectric door (a little difference), then the air track can be considered flat. Set the air rail left slightly
