摘要
分别对近似椭圆和精确椭圆建立数学模型,通过计算机对典型例子的计算,对用四心圆法作近似椭圆进行了偏差分析,找出了两曲线相背离的规律,以及与椭圆扁平率之间的关系。
This paper makes mathemat ic al models of approximate ellipse and exact ellipse separately.Makes error anal-ysis of the approximate ellipse by computing typical examples with computer.F inds out the regular pattern of error between the two curves and the relations hip to the flat ratio of ellipse.
