| 摘 要： | 回归分析法是对一定的测量数据，寻找出隐藏在随机性中的统计规律性．在考虑滑块和导轨之间空气黏性阻力的情况下，利用二元线性回归分析法直接验证牛顿第二定律，改进了牛顿第二定律的传统实验验证方法．结果表明，在实验误差允许的范围内牛顿第二定律均能得到较好地直接验证．

| Abstract: | For certain measurement data,the regression analysis is a method to explore the statistical regularity which is hidden stochastically. By taking into account the effect of the air viscous drag within the pneumatic cushion and the slider, the method of dualistic linear regression is adopted to verify the Newton second law directly. This approach is an improvement on the traditional verification experiment of the Newton second law. Results from this study indicate that direct verification of the Newton second law could be achieved satisfactorily within the permissible range of error. |
