摘要
在Matlab环境下,根据不同的情况,分别用三次样条插值和最小二乘分段多项式拟合的方法,对发动机磨合试验数据进行处理,得出了精确的关系曲线,为进一步研究发动机的性能提供参考.
The engine running-in testing data were processed based on the cubic spline method and least-square piecewise polynomial fitting method according to different situations in the Matlab environment,and precise curves were obtained which lay a sound foundation for further engine research.
