摘要
利用解析法确定轴测图椭圆作图四段圆弧的圆心和连接点坐标，从而获得较简便地绘制椭圆的作图方法。
A method of construction about Ellipse Axonometry this paper discusssed the method of analysis employed to deteimine the centre of a circle with fowr segments of circular arc and a coordinate of junction axonometry ellipse, thus acquiring an easy way of drawing ellipses
