摘要
根据国际计量局颁布的"测量不确定度表示指南",推导出了毛细管法、落球法和旋转柱体法3种常用的液体黏度测量方法的合成标准不确定度的评定公式,使液体黏度测量误差的评定更加客观全面,从而更好地反映测量效果.
In the light of Guide of Measurement Uncertainty promulgated by BIPM, this paper deduces expressions of evaluating combined standard uncertainty of measurement of measuring liquid viscosity utihzing the three kinds of liquid viscosity measuring methods: capillary and falling ball method and rotatory cylinder method, so that evaluating measurement error of liquid viscosity can be more objective and all-sided, reflecting measuring effects still better.
