【摘要】 １９９６年５月，中国计量科学研究院参加了电压交直流转换标准国际比对。比对结果为，国际传递标准相对于全国的基准在１ｋＨｚ频率下，交直流转换误差为（－０．４６±０．３１）×１０－６（ｋ＝１），与国际平均值相差０．５×１０－６。更多还原

【Abstract】 Abstract In May 1996,the National Insitute of Metrology(NIM) participated in the international comparison of the AC DC voltage transfer standard.The results of comparison are that,the AC DC transfer error of the international transfer standard with regard to the national primary standard is (-0 46±0 31)×10 -6 (k=1) at frequency less than 1kHz.The difference between NIM’s result and the international average value is 0 5×10 -6 .更多还原
