摘      要：To meet the de ma nds of high stability and sustainable temperature measurements over time,TIPC-CAS in China and LNE-Cnam in France have jointly developed single-pressure refractive-index gas thermometiy(SPR1GT),which is expected to be an alternative primary thermometiy because of its 0.25 mK accuracy and high measurement speeds.
