| 摘 要： | 现行的工程制图教材中,轴线正交的圆柱贯穿圆锥时,其相贯线的某些特殊点总是近似求出.文章以正投影理论为基础,以圆柱贯穿圆锥的数学模型为依据,提出了其相贯线上某些特殊点的准确求法,为手工及计算机准确绘制该相贯线提供了依据.

| Abstract: | When solving the intersecting curve formed by a cylinder going through a cone with their two axles at right angle,most of the current textbooks only provide methods which approximate the position of the special points.Based on the theory of direct projection and taking the theoretical modeling of a cylinder going through a cone as the reference,this article suggests methods that can accurately solve the positions of some special points on the intersecting curve.Hence,more accurate drawing,manually or by computer,of intersecting lines become possible. |
