摘　　要：分析了用辅助球面法和换面法求圆锥与圆球各种位置相贯线的投影作图过程,为辅助球面法的求解提供了较多的示例和思路,也为求复杂回转体交线的作图过程提供了借鉴,并通过CATIA三维模型佐证求解相贯线的正确性,进而使求解过程直观、准确、方便。The projection construction process of intersection of cone and sphere in some spatial locations is analyzed by the auxiliary-sphere method and projection-transformation method.It provides several samples and some clues for the implementation of intersections of basic and complex rotational solids by auxiliary-sphere method.The correctness involved in above is verified by 3D hybrid modeling on CATIA software,in which it makes the construction process pictorial,perfect and convenient.
