近似椭圆误差的计算机辅助分析与修正

在工程制图中经常采用一些近似画法绘制椭圆,本文通过对菱形法画椭圆所产生的轮廓误差的量化分析，提出了一种修正方法，可使绘出的椭圆愈加精确，同时，还利用计算机技术得到了一些有价值的曲线图，为绘图人员用菱形法精确绘制椭圆提供了理论依据和技术指导.

Computer Aided Analysis and Improvement for the Errors of the Approximate Ellipse

This paper analyses the errors of the approximate ellipse constructed with the rhombusmethods, on the basis of it, An improvement method is put forward and a few diagrams ofcurves are obtained on the PC. therefore, It is very important and helpful for us to exactlyconstructed an approximate ellipse with the rhombus method.
