本刊1978年第4期发表了李耀南同志的《以氮点代替氧点检定0到负200℃铂电阻温度计》一文,引起了低温检定工作人员的注意。该文作者在实验的基础上进行了大量的计算,证实这种替换是可以的。同时该文还提出了两种计算方法。我们认为该文论证的方法是可行的,提出的数据也准确可靠。但是,在具体分析与计算的某些细节上看来尚未谈透,本文拟就个人在这方面工作中的一点体会作几点补充,供大家参考。
The fourth issue of 1978 issue of Comrade Li Yaonan, “the nitrogen point instead of oxygen point 0 0 to negative 200 ℃ platinum resistance thermometer,” a text, causing the staff of low temperature verification staff’s attention. The author based on the experiment carried out a large number of calculations to confirm that such a replacement is possible. At the same time, the paper also proposed two calculation methods. We think the method of argumentation is feasible and the data presented are accurate and reliable. However, it seems that some details of specific analysis and calculation have not been thoroughly discussed yet. This article intends to make a few supplements to the personal experience in this field for your reference.
