摘要
本文提出了一种应用计算机对热电偶传输特性进行二次回归拟合的方法。该法以标准热电偶传输特性的高次方程为基础,用户根据所选用热电偶的实际工作温度范围与允许误差,应用本文所介绍的处理方法及程序使可获得一组能满足给定精度要求的热电偶二次回归拟合方程,且这组方程的数自为最少。
This paper presents a methcd for quadratic regression fitting of thermeceuple transfer property to study its computer realization and form a software package. By means of this sofiware, the cusiomer can quickly obtain a set of conic equations which best fit the transfer property of thermccouple under given temperature range and permitted error. The number of this set of equations is much smaller than that of a straight line fitting. This is very useful in the desigh of intelligent thermo-engineering instrument.
