1988年10月举行的国际计量委员会(CIPM)第77次会议决定,从1990年1月1日起在世界范围内启用量子化霍尔电阻标准。中国计量科学研究院从1987年起也开始了建立量子化霍尔电阻标准的研究课题,该项标准现已建成,用量子化霍尔效应复现的10kΩ和1kΩ电阻量值的不确定度为2.2×10~(-8)。
The 77th Meeting of the International Committee on Measurement (CIPM), held in October 1988, decided to start using the quantized Hall resistance standard worldwide from January 1, 1990. China Institute of Metrology also started the research project of establishing quantized Hall resistance standard since 1987, and the standard has been completed. The uncertainty of 10kΩ and 1kΩ resistance values reproduced by quantum Hall effect is 2.2 × 10 ~ (-8).
