摘要
利用排水方法,使水面稳定下降,通过力传感器测定物体所受拉力随时间的变化曲线.改进后的实验装置,可以观察到水块的变化过程,能够直观获得拉力的变化情况及其最大值,并探究其他因素对实验的影响.
The authors use latex pipe to drain and lower the water level steadily, and utilize force sensor to measure the time dependence of the pulling force. Using this improved device, the changes and the maximum of the pulling force are observed directly. The influence of other factors in the experiment is explored.
