摘　　要：落球法测液体粘滞系数是大学物理实验中一个重要的验证性实验,其人为操作原因会对实验的精准性造成很大影响。该文通过对实验数据的测量、计算与对比,讨论并分析了在操作过程中引起粘滞系数误差的主要人为因素,并针对这些因素对实验仪器和实验操作方法进行了改进,从而达到减小实验误差的目的。The determination of liquid viscosity coefficient is an important verification experiment in the physics experiment of the university. The reason of its operation will greatly affect the accuracy of the experiment. In this paper, the main factors that cause the er- ror of viscous coefficient during the operation are discussed and analyzed through the measurement, calculation and comparison of the experimental data. The experimental instrument and the experimental operating method are improved for these factors so as to achieve the objeetiveof reducing the experimental errors.
