摘    要: 在仿射变换里,圆的对应曲线是椭圆,利用它们的仿射对应关系即仿射性质可求出圆在任意平面上的射影—椭圆(求出长短轴或共轭直径,用多种方法画椭圆).从而解决一般高等院校制图教材中较少提到的画椭圆的理论根据问题和多种画法的问题。

关 键 词:  椭圆  对应  仿射

Abstract:In corresponding and imitating system, the curve corresponding with circle is ellipse. The projection of circein any projection surfaces can be obtained by using corresponding and imitating principle the ellipse(Firstly, the major and minor axis of the ellipse or its conjugate diameter is obtained and than different methods are used to draw this ellipse). This article provided the theory and different kinds of methods to draw a ellipse which could fill a vacancy in Academic teaching materias.
Keywords:Circle  Ellipse  Correspond  Imitate
