An estimate of the radial temperature non-uniformity (gradient) effects on the cryogenic thermometer calibrations is often required in order to make sure of the total uncertainty. A method of determining such effects is presented. For two resistance thermometers of the same type, the necessary condition of zero gradient effects is that the ratio of their resistances remains unchanged throughout the test in spite of the temperature fluctuations of the comparator block; whereas the sufficient condition is...

An estimate of the radial temperature non-uniformity (gradient) effects on the cryogenic thermometer calibrations is often required in order to make sure of the total uncertainty. A method of determining such effects is presented. For two resistance thermometers of the same type, the necessary condition of zero gradient effects is that the ratio of their resistances remains unchanged throughout the test in spite of the temperature fluctuations of the comparator block; whereas the sufficient condition is that there are no constant synchronous temperature differences between the thermometer sites. The gradient effects can be obtained, therefore, from the deviations of the measured data from these two conditions. An example is given. Discussions are made on the experimental factors.

在分析低温温度计的校验误差时,需要估计温度不均匀性的影响.本文提出一个估计这种影响的方法.若使用同一型号的两支电阻温度计进行测试,则径向温度理想均匀的必要条件是两温度计的电阻比不因温度起伏而变化,充分条件是两温度计所处部位之间无同步温差.分析测试数据对这两个条件的偏离,就可以估计出温度不均匀性的影响.文中给出方法应用实例,并对实验条件进行讨论.
