摘　　要：本文对气轨实验中时间量的不等精度测量进行了研究，采用了单管光电门改成双管光电门的方法，实现了时间的同次测量。将双管光电门应用于动量守恒定律，得到了较满意的效果。In this paper,the research is made on the measurement of the unequal precision of the amount of time in air cushion orbit experiment.The change of single- tube photoelectric door to two-tube photoelectric door is done,effecting the measuremenr of time in the meantime.When the two-tube photoelectric door is applied to the law of conservation of momentum.the satisfied results are obtained.
