摘　　要：通过对落球法粘滞系数测定仪的分析而获得实验误差来源,通过提高实验技巧而克服仪器的弊端,使小球沿容器中心轴线准确下落,从而提高了实验成功率。The sources of experimental errors are obtained by analyzing the liquid viscosity instrument by falling-sphere method. It can be avoided by improving the experimental skills and the ball will flow precisely along the central axis of the vessel in order to increase the success rate of the experiment.
