| 摘 要： | 对活塞式液体流量标准装置体积校准方法进行了研究,基于理想圆柱体模型建立了活塞装置体积模型,引入修正系数对所建立的体积模型进行修正,并利用质量守恒定律提出采用质量法对活塞装置进行体积校准.对修正系数进行赋值分析和不确定度评定,结果表明5L及以上体积的扩展不确定度优于0.05％.该方法操作简便,可控性好,结果准确可靠.

Discussion on Volume Calibration Method of Piston Liquid Flow Standard Device |
| |
| Abstract: | The piston liquid flow standard device volume calibration method of piston device volume model based on ideal cylindrical model is studied,the volume of the model is modified by introducing a correction factor,and quality method for calibration of the piston volume device using the law of conservation of mass is put forward.The correction coefficient is analyzed and the uncertainty is evaluated.The results show that the expanded uncertainty of 5L and above is 0.05％.The method is simple,controllable and accurate. |
