摘要
对碰撞打靶实验中的能量损失,先作理论估算,再通过实验验证.讨论二者不一致时如何获得修正值以及测量值的显著性检验问题.还讨论了实验的不确定度估算问题.得出的结论是碰撞打靶实验过程中的能量损失大部分源于非弹性碰撞,其余主要来自空气阻力.
Theoretical estimates and experimental tests of the energy loss in collision target shooting experiment have been carried out.When the experimental test doesn′t match the theoretical estimate,correction worth obtaining and significance test of the measurement data have been discussed.Estimation of the experimental uncertainty has also been investigated.The conclusion is that the most of the energy loss in the process of collision target shooting originates from inelastic collision,the rest from air resistance.
