IMPROVEMENT OF FITTED POLYNOMIAL METHOD FOR DIFFERENTIAL COEFFICIENT THERMAL EXPANSION

摘要：

This paper presents a new method of data fitting, that is,interpolation-fitting method for measurement of differential coefficient of thermal expansion considering practical application.This method only uses a few points to interpolate and then fits the data by least square method,which can reach higher fitting accuracy in some cases.In practice, a few measuring data can fit curves with relatively high accuracy,which reduces the amount of work and has good practicability.
