摘要
在过去十年左右的时间里，NBS对先前报道的三个电单位相关基本常数实验的结果进行了新的处理，得出了许多重要量的精确、间接的国际单位制值。其中包括精细结构常数α、阿伏伽德罗常数NA、约瑟夫逊频率电压比2e/h和量子化霍尔电阻R h lect h/e 2。
New Results From Previously Reported NBS Fundamental Constant Determinations.
A new treatment of previously reported results of three electric-unit-dependent fundamental constant experiments carried out at NBS over the last decade or so yields accurate, indirect values in SI units for a number of important quantities. These include the fine-structure constant α, the Avogadro constant NA, the Josephson frequency-voltage ratio 2e/h, and the quantized Hall resistance RH≡h/e2.
