一阶变速直线运动中收尾位移的实验近似

The Approximate Calculation of Terminal Displacement in Experiment at the Fist Order of the Change Speed Linear Motion

针对目前许多实验中出现的一阶变速直线运动问题的收尾速度和运动位移的关系进行分析探讨,从理论上推导理论值和实验近似值的大小,结合目前流行的综合性设计实验——磁阻尼系数和动摩擦系数测定实验。提出了在此类实验中解决此类问题的方法,提高了实验的精确度。

From the terminal displacement of the change speed linear motion with the fist order, the author deduced the sizes of the theories value and the approximation value in experiment and found the method to solve the problems in the experiment. Based on the popular experiment at the present of measurement of magnetic-damped coefficient, it was proved able to improve the accuracy of the experiment.
