摘要
本文介绍了把超越多项式转换为多元线性方程之后,应用逐步回归分析方法进行处理,以满足温度测定中热电偶分度值公式的反算问题,即解决在工业生产自动测量中测定出热电势求温度的问题,使IEC国际标准得到完善和补充。
A stepwise regression analysis is introduced in this article. Based on the analysis, the multinariate linear equation deduced from a transcendental polynomia is treated to solve the problem of inverse calculation of graduation value formula for for thermocouple. As a resalt, the tamperature can be determinad by the thermoelectromotive force during the course of indudus-trial measarement Therefore the IEC international standards could be improved.
