辅助平面-椭圆法及其应用

Aided Plane-Ellipse Method and Its Application

辅助平面—椭圆法是利用平行干椭圆长、短轴的直线,且与椭圆相交交点的仿射变换原理建立的图解法。该法不但克服了辅助球面法的不足,还纠正了偏交时不适合图解法的偏见。文中还简介了斜交、偏交的作图方法与步骤,该法是一种新型的图解法。

A method of aided plane-ellipse is based on the principle of affine transformation of intersection points in which straight lines parallel to long or short axis of an ellipse intersect the ellipse.The method overcome the prejudice against the fact that the drawing method can't be used for resolving the problem with slopping in- tersection as well as some defect from the method of aided surface of sphere.The drawing of both slopping and partial intersections and the procedure are given in our paper.The method is a new—type diagramming approach.
