摘要
本文介绍用最小二乘原理借助计算机对实测叶型数据进行了最佳分段拟合的思想和数学模型的表述,最佳分段点的求法,实现步骤和程序的N-S图的建立.并通过实例验证了这一方法的有效性.
The concept optimal sectional fitting of copy plotted data of profiles with the method of least square is presented together with a mathematical model for computer calculation. The paper also shows ways of determining optimal sectional points, steps of calculation and how to set up the program's N-S diagram.Actual examples demonstrate the effectiveness of the method. Fig.1, tables 4 and refs.10.
