摘要
本文从解析分析的角度对画法几何中两立体（圆柱与圆锥）表面正交时交线的投影进行了分析，为作图提供了理论依据，这样可大大避免作图的盲目性，同时为计算机绘制交线（相贯线）提供了数学模型。
This article analyzes in terms of the resolution analysis of the projection of the trace formed by two perpendiculaly intesected rotatory faces (a cylinder and a conus) in the descriptive geometry, thereby providing the theoretical basis for drawing so that blindness may be avoided. The obtained equation may be used as the mathematic n1odel in trace (intersection) drawing with computers.
