在热电偶的实际应用过程中，分度点往往需要根据校准点用高阶多项式进行拟合求得。本文首先确定最优的多项式拟合阶次，同时鉴于目前国际上对校准结果表示的规范化要求，每一个校准结果都有一个不确定度与之相对应，本文对最优的多项式拟合结果的不确定度进行了评定。

In practical application of the thermocouples, we usually use high-order polynomial fitting to obtain the dividing spots on base of calibrating spots. This paper presents the best order of polynomial fitting. In view of the international normalization requirements on the representa-tion of calibration results, an uncertainty was offered for each calibration result. This paper evaluates the uncertainty of the results of the quadratic polynomial.
