| Abstract: | In the light of least square method principle,this paper carries out quadraticmultinomial fitting about characteristic curves of seven kinds of common standardthermocouples by means of automatic dividing segment method on computer.The fittingprecision is high. The fitting results of the seven kinds of thermocouples can be used aspractical reference for the personnel working on the measurement of thermocoupletemperature. |
