我国为实施1990国际温标,由中国计量科学研究院承担的国家重点项目.研究建立国家高(961.78℃以上)、中(419.527℃至961.78℃)、低(1.2℃至273.16℃)段温度基准装置.现已全部研制完成。除中温段基准已在1992年初通过鉴定外,近日高温和低温段基准研究又奏凯歌。经过专家鉴定.我国
China is a national key project undertaken by China Institute of Metrology in 1990 to implement the international temperature scale test.We set up a temperature reference device of national high (above 961.78 ℃), middle (419.527 ℃ to 961.78 ℃) and low (1.2 ℃ to 273.16 ℃) Has been fully developed. In addition to mid-temperature benchmark has passed the appraisal in early 1992, the recent high temperature and low temperature benchmark study also played triumphant song. After expert appraisal.
