摘要
用数学解析方法,论证某些非回转面存在圆截面,在与回转面相交时可用辅助球面法求相贯线。并分析了辅助球心的位置和球半径。
That some non-turning surfaces have circular sections is proved by mathematical analysis in the paper. And when the circular surface is intersected by a turning surface, the intersecting line can be obtained by Auxiliary Spheric Surface. Also, the location of the center and the spheric radius are analyzed.
