摘要
本文对轴线斜交，且两轴线平行于某一投影面的圆柱面与圆锥面相贯时，相贯线上的特殊点进行探讨，从而得出了用辅助球面法不能求出该相贯线上的最右点的结论。
When cylinder surface and cone surface penetrate each other,if their axises intersect slantly and are parallel to the frontal projecting plane,there will he special points in the penetrating line. This paper studies these points and draws the conclusion that the rightest point in the penetrating line can not be got by means of drawing spherical surface.
