摘要 长期以来,在接触测温学、非接触测温学和辐射度学领域对铜凝固点(1084.62℃)以上高性能温度固定点有着迫切的需求。随着高温金属(碳化物)-碳共晶熔点的发现,这个需求将很快得到满足。本文简要介绍了高温金属(碳化物)-碳共晶固定点的国际研究计划,这个研究的目的是用新的定义替代当前温标ITS-90在银点(961.78℃)以上的定义,使不确定度比当前温标低5-10倍。 There has been an urgent requirement for high performance fixed-point above the copper freezing point (1084.62℃),in contact thermometry, non-contact thermometry and radiometry for a long term. With the discovery of high temperature metal (earbide)-earbon (M(C)-C) euteetie melting points, this requirement will soon be met. This paper briefly introduced the research project for high temperature metal (earbide)-earbon (M(C)-C) euteetie fixed- points in the world. The purpose of the research is to substitute the current definition of ITS-90 above the silver point(961.78℃) with a new definition, make uncertainty 5-10 times lower than oresent temoerature scale.
