自68国际实用温标正式通过以来,巳将近二十年了。这段时间内一直围绕继68国际实用温标之后的温标可能形式展开讨论。的确,在相当一段时间里认为1987年可能为通过新温标的日期。在70年代末期,有关计温学方面大量新工作已经取得成果。从0.5K 至金点1337K 整个范围内,热力学温度的测量已基本上完成或取得很大的进展。我们发现,热力学温度与国际实用温标明显不同,其差值比原来所估计的要大得多,特别是在0℃至460℃范围内。在0℃以下,铂电阻温度计内插方程的新工作表明,可建设一个新方程,比68温标中所使用的更精确更简单,此外还大大
It has been nearly 20 years since the formal adoption of the International Practical Temperature Scale. This period of time has been around the following 68 international practical standard temperature scale after the possible form of discussion. Indeed, for a considerable period of time 1987 is likely to be the date of the adoption of the new temperature gauge. In the late 1970s, a great deal of new work has been done on thermometry. From 0.5K to the golden point 1337K throughout the range, the thermodynamic temperature measurement has been basically completed or made great progress. We find that the thermodynamic temperature is significantly different from the international practical temperature scale, and the difference is much larger than originally estimated, especially in the range of 0 ° C to 460 ° C. Below 0 ° C, the new work of the platinum resistance thermometer interpolation equation shows that a new equation can be constructed that is more accurate and simpler than the ones used in the 68 temperature scale,
