1991年第4次米定义及其相关量咨询委员会(CCM)会议上讨论了有关千克重新定义的可能性及在第5次CCM会议上邀请有关实验室所作的实验进展的报告。 1.一般评述约20年前,均致力于为建立千克与电单位或高准确度自然常数之间联系的各种实验装置。这些实验达到的重复性可能好至足以监视
A report on the possibility of a redefinition of the kilogram and the invitation to make an experiment on the laboratory at the 5th CCM meeting was discussed at the 4th Rice Definition and CCM meeting in 1991. 1. General comments About 20 years ago, various experimental devices dedicated to establishing links between kilograms and electricity units or high-precision natural constants were committed. The repeatability achieved by these experiments may be good enough to monitor
