摘要
提出样条插值拟合热电偶特性(温度—电势)的基本原理。讨论了插值条件、连接条件,以达到插值精确度及拟合曲线的光滑连接。在400～1200℃范围内求出了镍铬-镍硅(K型)热电偶温度电势的拟合公式及插值表格。
The basic fitting principle of thermocouple character-istic (temperature vs. potential) with sample inter-polation method is stated. To make smooth connec-tion on fitting curve and meet the accuracy of the interpola-tion, the interpolation condition and connec-tion limits are discussed. The fitting formula and interpolation table for Ni-Cr Ni-Si(K) thermocouple curve in the range of 400 to 1200℃ are obtained.
