介绍并讨论了 1 999年中国计量科学研究院 (NIM)和日本计量研究所 (NRLM) ,在NRLM用光电高温计在高温黑体炉上进行的高温温标的国际比对。比对结果 ,显示两国温标的一致性 ,从 1 0 0 0℃～ 2 2 0 0℃优于± 1℃。
An international comparison of the high temperature temperature scale performed by the National Institute of Metrology (NIM) and the Japan Institute of Metrology (NRLM) in 1999 on a high temperature blackbody furnace using a photoelectric pyrometer was introduced and discussed. The comparison results show that the consistency of the temperature scale between the two countries is better than ± 1 ℃ from 100 ℃ to 2200 ℃.
