| 摘 要： | 对过椭圆外一定点的法线作图问题给出了一种计算机实现的几何逼近方法。该方法以几何迭代逼近作图原理为基础,建立了新的逼近法线方程,从而避免了手工作图的低精度及实际操作时的繁琐,使过椭圆外一定点的法线作图问题得以在计算机上迅速获得解决,且可达到足够的精度要求。

| Abstract: | Here is a geometric approach computer method on the graphic problem of ellipse normal through a point outside the ellipse According to the principle of the geometric approach graphic method, the new ellipse normal equations are advanced. In line with the equations, ellipse normal through a point outside the ellipse can be obtained with enough accuracy by computers. |
