  • 本文对在给定水的三相点的绝对温度以一定的数值(例如T3=273.1700),同时以绝对温标代替摄氏温标以后所引起的一些实际问题作了讨论。这些问题包括气体温度计的改正及电阻温度计和温差电偶温度计的规定。本文指出,在以绝对温标为标准以后,寻求冰点的绝对温度与对气体温度计的改正两种工作统一起来了。又指出,在以绝对温标为标准以后,绝对温度测量的精确度将大大提高。

     

    Some practical problems arising from the adoption of the absolute scale ol temperature as standard in place of the Celsius scale are discussed. The absolute scale is fixed by assigning a numerical value (say T3=273.1700) to the triple point of water. The problems 'considered include the correction of gas thermometer readings, the specification of: the platinum resistance thermometer and of the platinum thermocouple. It is pointed out that, when the absolute scale has been chosen as standard, the determination of the absolute temperature of the ice point and the correction of gas thermometers become one and the same task. It is further pointed out, that the accuracy in the experimental determination of the absolute temperature will be greatly increased.
