| 摘要: |
| 标准铂钴电阻温度计是0.65~24.556 1 K（氖三相点）温区重要的测温器件,特别是高稳定的标准铂钴电阻温度计有潜力作为温度标定和温度国际比对的数据载体。为筛选出高稳定的标准铂钴电阻温度计,在前期研究基础上,建立以制冷机为冷源的温度计低温考核装置,5 K控温稳定性达13 μK,24.556 1 K控温稳定性达27 μK,优于当前同类考核装置公开报道的控温稳定性结果。基于此,在5~24.556 1 K温区开展标准铂钴电阻温度计百次低温温循研究,获得5支高稳定的标准铂钴电阻温度计,其中,4支50 Ω标准铂钴电阻温度计的稳定性均优于0.2 mK@24.556 1 K,1支100 Ω标准铂钴电阻温度计的稳定性优于0.5 mK@24.556 1 K,为当前标准铂钴电阻温度计低温稳定性国际最好结果。未来本文筛选的高稳定性标准铂钴电阻温度计将用于低温温度标定和低温温度国际比对等相关应用和研究。 |

| Abstract: |
| Standard platinum cobalt resistance thermometers (SPCRTs) are important temperature sensors used in low temperature region especially from 0.65 K to 24.556 1 K (triple point of neon), and high stability ones have the potential to be used as the data carrier for temperature calibration and international comparison. Based on our previous research, this article establishes a low temperature assessment system with temperature control stabilities of 13 μK at 5 K and 27 μK at 24.556 1 K. It is currently the most stable low temperature assessment systems reported in the world. Based on the system, stability of the developed SPCRTs is investigated under hundred low temperature cycling from 5 K to 24.556 1 K, and five high stability SPCRTs are obtained. Among them, the stability of four 50 Ω SPCRTs is better than 0.2 mK and the stability of one 100 Ω SPCRT is better than 0.5 mK at 24.556 1 K, which is the best international result for low temperature stability of SPCRTs. In the future, the high stability SPCRTs selected in this article will be used in the relevant applications and research of temperature calibration and international comparison at low temperatures. |
