本文通过对大量试验数据的统计分析,比较多项式、间接多项式、修正多项式三种数学模型拟合燃油消耗率曲线的拟合效果,提出了采用修正多项式拟合法可获得最佳拟合的结论,进而提供了建立这种数学模型的计算方法和程序设计思想,并应用于试验数据的整理工作中。 In this paper, the statistical analysis of a large number of experimental data, comparing polynomial, indirect polynomial, polynomial correction polynomial fitting of the fuel consumption rate curve fitting effect, the use of modified polynomial fitting method to obtain the best fit conclusions, and thus Provides the calculation method and program design idea to establish this kind of mathematical model, and applies it to the finishing of experimental data.
