以匀加速-匀速-匀减速运动为例，分析了测量误差与加速度之间的关系，仿真结果验证了该方法的可行性。
From a numerical simulation on a practical possible mode: uniform acceleration-uniform speed-uniform deceleration we obtain the relationship between the measurement error and the acceleration value.
假如小车起先是静止的，然后把它推一下，以后它便以一定的速度匀速地运动。
If the cart is initially at rest and then given a push, it afterwards moves uniformly with a certain velocity.
