| 摘 要： | 根据方程ｘ＾２／ａ＾２＋ｙ＾２／ｂ＾２＝１设计的四杆机构，研究了该机构不需计算椭圆长短轴，焦距，并且略去其中一个移动副，在有限的结构范围内画出足够大或小的椭圆的运动机构－椭圆绘较仪。实验证明该机构可实现一次完成完整椭圆曲线的绘制。

| Abstract: | According to the equationx 2a 2+y 2b 2=1, the author designed the four-pole elliptic drawing instrument which doesn't need to calculate the long and short axis and focus and also omitted one of its layshaft so as to guarantee to draw a enough large or small ellipse.It was proved that the drawing instrument can operate a whole ellipse one time. |
