摘要
用空间解析法对画法几何教材中不明了和有疑义的柱(球)锥相贯线特殊点给以证明,从而在其相贯线的作图中,明确地应用这种利用圆锥内切辅助球面法得到特殊点投影的作法。
In this paper, the writer proves the unclear and doubtful point by using Space Analytic Geometry which is the special point in the intersecting line of Cylinder (or sphere) and Cone in the textbook and teaching material of Drawing Geometry. Thus, we clearly apply this way of doing the inscribed auxiliary spherial surface to the course of drawing its intersecting line so as to find the solution of the projection drawing of its special point.
