空气中双称重法砝码体积测量方法实验研究
Experimental Study on Volume Determination of Weights by Double Weighting in Air Method
摘要
Abstract
A comparative experimental study was conducted on the volume determination of standard weights with a mass of 1 g～5 kg,using the double weighing in air method and the hydrostatic method.A method for measuring the volume of auxiliary weight plates was proposed,which solved the problem of small weights ranging from 1 g to 5 g that cannot be directly loaded onto the scale plate.The uncertainty of weight volume measurement was evaluated by Monte Carlo method,and it was found that the consistency of the weight volume and its uncertainty measured by the double weighing method and hydrostatic method was very good,and the relative uncertainty of the weight volume decreased with the increase of the nominal mass when the nominal mass of the weights was 1 g～1 kg,and increased with the increase of the nominal mass when the mass was more than 1 kg.关键词
