发动机万有特性曲线的曲面拟合

The Least Squaresfit Method for Engine Performance Map

介绍了最小二乘曲面拟合方法，编制了相应的计算机程序，将发动机万有特性曲线表示为多项式形式。实例计算结果证明了该方法的实用性。

The least squaresfit method is presented and its computer programme has becn fabricated. With the method,the engine performance map can be expressed in the form of multiplex equations. Calculating examples have proved the practicability of the method.
