摘要 介绍了中国计量科学研究院研制的用于分度热电偶的Co—c高温共晶点，以及使用铂／钯热电偶对共晶点进行的复现测量的结果。实验数据表明，Co-c高温共晶点的熔点复现性已达到了0．03℃。Co—C高温共晶点坩埚在1300℃以上温度经历了累计时间500h、110多次的熔化和凝固实验后依然完好。 The method of construction of Co-C high temperature fixed point for thermometer calibration and the testing results of reproducibility with thermoeouple at National Institute of Metrology of China are introduced. The experimental data show that the reproducibility of melting point of Co-C cell is 0.03 ℃ using Pt/Pt thermocouple, and the cell is robust after 110 melting and freezing cycles with 500 h above 1300 ℃.
