摘要
讨论了由二元函数拟合描述效率曲面的方法，阐述了利用计算机用Ｔ－Ｎ算法来求取等效率线，探讨了由正等轴测变换实现三维及二维显示的方法．
The method of describing the efficiency curvature by binary function fitting is discussed in this paper. The T N algorithm is expouned to caculate the equi efficiency curve. The 2D and 3D figure is also plotted by means of orthographic projection.
