摘要
对ITS-90温标在83.8058~273.16K温区内的温标的非唯一性进行了研究。在高精度低温恒温槽内对九支套管铂电阻温度计进行分度,分析其非唯一性,并研究此温区与13.18~273.16K温区的非一致性。
Nine capsule type platinum resistance thermometers are selected to be calibrated in the low temperature comparison cryostat. The nonuniqueness is studied in the temperature range from 83 8058K to 273 16K. Further, the inconsistence of this range compare with the full range from 13 8K to 273 16K is discussed.
