摘　　要：就“转柱法测液体粘度”实验中的侧面粘滞力矩、端面粘滞力矩和摩擦力矩对实验的影响进行了讨论;特别是导出端面粘滞力矩的计算公式,用它进行误差修正效果明显。This paper discusses the influence of side viscosity moment, end viscosity moment and frictional moment on the experiment, and induces the calculation formula of end viscosity moment. When this formula is used to correct the error, the effect is very clear.

关 键 词：转柱法 粘滞力矩 误差
