摘要
本文对一类相贯线(其投影为二阶曲线)的特位点给出了通用而简明的作图法,继之用解析法及几何变换法对作图的正确性及其相关问题予以系统证明,并通过实例使此类问题较完满得到解决。
Presentation is given of a brief and universal description method of the point of specail place of those intersection lines of solids whose projection is a quadratic curve. Sysematic proof is made of the correctness of this method and some other rakted problems by employing the analytic approach and geometrical transformation. And a nearly perfect solution is reached through a number of illustrations.
