一、前言 本文采用回归分析的方法,对373台合格发动机的性能数据进行统计分析,建立台架性能曲线的回归分析式,并用其代替苏联提供的绘制台架性能曲线板来验收发动机。这在工程应用上是可靠的。该方法不仅能简 I. INTRODUCTION This paper uses the method of regression analysis to conduct statistical analysis of the performance data of 373 qualified engines and establish the regression analysis of the bench performance curve and use it instead of the drawing bench performance curve provided by the Soviet Union to check the engine. This is reliable in engineering applications. This method can not only simplify
