摘　　要：MFC具有强大的算法功能、稳定的固定界面、执行效率高、运行快等优点。本文针对S型标准热电偶热电势求取问题,结合标准热电偶溯源证书及GB/T 16839.1-2018《热电偶第1部分:电动势规范和允差》规定的公式,通过解一组三元一次联立方程确定差值函数,使用MFC完成S型标准热电偶分度表的设计。最后通过与JJG 75-1995《标准铂铑10-铂热电偶检定规程》及标准铂铑10-铂热电偶溯源证书中对应数据比对,进行结果验证。MFC has the advantages of powerful algorithm function,stable fixed interface,high execution efficiency and fast operation.Aiming at the problem of obtaining the thermal potential of S-type standard thermocouple,combined with the traceability certificate of standard thermocouple and the formula specified in thermocouple Part 1:electromotive force specifications and tolerances(GB/T 16839.1-2018),this paper determines the difference function by solving a set of three-dimensional primary simultaneous equations,and uses MFC to complete the design of S-type standard thermocouple graduation table.Finally,the results are verified by comparing with the corresponding data in JJG 75-1995 verification regulation of standard platinum-10% Rhodium/platinum thermocouple and traceability certificate of standard platinum-10% Rhodium/platinum thermocouple.
