摘　　要：本文介绍一套基于落球法的液体黏滞系数测量装置及实验方案。利用舵机和吸管组装的释放装置可以稳定控制小球的释放位置,确保其能够沿着容器的中轴线下落。将不同规格的量筒与不同材质大小的小球进行搭配,获得了多组实验数据,并详细分析了各物理量对总误差的贡献比例。This paper introduces a set of liquid viscosity coefficient measurement device based on drop method.The release device assembled with the rudder machine and the straw can stably control the release position of the small ball,ensuring that it can fall down along the central axis of the vessel.The measuring tubes of different specifications were matched with the small balls of different material sizes,and the contribution ratio of each physical quantity to the total error was analyzed in detail.
