主　　题：temperature control temperature stability temperature resolution rhodium-iron resistance thermometer primary gas thermometry 

摘      要：We presented a relationship between the temperature control and measurement stability limit and the temperature resolution,particularly for using rhodium-iron resistance thermometers and AC resistance *** on this,temperature control was investigated and demonstrated in primary gas thermometry under various working *** optimized parameters,micro-Kelvin level temperature control stability was realized in the temperature region from 5 K to 24.5 *** temperature control stabilities are better than 8μK over 180 h with an integration time of 33.6 s in the concerned temperature range,closing to the limit that the sensors and the instruments can control and *** stabilities were significantly improved about(44±8)%at 24.5 K and(70±7)%at 5 K comparing with our previous work(Chen et al.,Cryogenics,2019,97:1–6).
