摘　　要：本文从验证动量守恒定律实验出发，在估计出误差大小和计算出恢复系数大小的基础上，分析了产生误差的主要原因和减小误差的方法，同时给气垫导轨上的物理实验怎样减小误差提供了参考。The author begins with the experiment on the test and verification of the Law of Conservation of Momentum.On the basis of the error estimated and the restorative co-efficient calculated,the author analyzes the major reasons why the error is produced and introduces some way to reduce it. This paper provide reference to the Physical experiment on how to reduce the error on air track.

关 键 词：粘滞阻力 阻尼常数 恢复系数 动量守恒定律
