| 摘 要： | 数据处理是发动机特性试验的一个重要内容，是测取发动机各项指标，进行动力性、经济性分析的前提和基础。本文利用Matlab强大的数据处理功能和绘图功能对发动机的性能试验数据进行处理，并采用最小二乘分段多项式拟合法进行曲线拟合，既提高了工作效率，又可得出较为精确可靠的曲线方程和直观的拟合曲线。

| Abstract: | Dataprocessing is an important content of engine performance test, and it is theprem ise and basic of getting engine indexes and making analysis of dynam is and econom is perform ance. Using the powerful function of data processing and plotting of Matlab, this paper made processing to the data of engine performance test. A dopting the least square piecewise polynomial fitting method to fit curve, the precise and reliable curve equation as well as the intuitionistic fitting curve can be educed. |
