摘　　要：本文首先给出了一种求解椭圆周长近似值的作图方法,同时又导出其相应的求解公式。其次在对误差回归分析的基础上,获得了由此方法所求得的椭圆周长近似值的修正系数,从而在相当高的精度范围内,提供了一种在工程中适用且简单易行的求解椭圆周长的方法。In this paper, a method of rectifying the circumernce of ellipse and its corresponding formulas are described and the rectifying errors in various conditions are analyzed and compared. On the basis of regressive analysis, the correcting coefftcents are obtatned.The method has been proved to be of higher pricision and very convenient to use in enginecring.
