摘要
研究小球在低黏度透明黏性液体中以初速度为零状态下落的加速运动过程,通过分析小球在加速下落过程中下落速度与对应时间的关系而得到液体的黏滞系数值.新方法改进了原变速落球法研究拟合小球下落位移与对应时间得到黏滞系数的实验方法.实验结果表明,新方法提高了实验的稳定性和拟合的准确度.
The small ball in the low viscosity transparent sticky liquid tall with initial velocity is zero state ot accelerated motion process,through the analysis of small ball falling speed in the process of acceleration whereabouts and the corresponding time relationship to get liquid viscous coefficient values.The new method to enhance the stability of the experiment and the accuracy of the fitting.
