质量基准量值传递过程中空气浮力影响的研究
Study on the Influence of Air Buoyancy for the Dissemination Based on Mass Primary Standard
摘要
Abstract
The CIPM-1981 formula,the CIPM-81/91 formula and the CIPM-2007 formula are used to calculate the air buoyancy correction during the dissemination of mass primary standard respectively,there are some differences among these results.In order to analyze the influence of three formulas on the air buoyancy correction,the calculation results of air buoyancy correction is compared under different conditions.The results show that the maximum difference is 42 μg under different environmental conditions,when the volumes of national kilogram primary standard No.60 and national kilogram secondary standard No.121 have known.关键词
