【摘要】 本文通过数学分析法导出了两个二次曲面体轴线相交时,相贯线在对称面上投影的解析式和极值点的坐标关系式,并由此给出了求相贯线极值点的准确作图方法,从而为计算机绘图提供了数学模型。更多还原

【Abstract】 In this paper,an analytic expewssion of the projective intersecting lines on a symmetri- cal surface has been developed under the condition of intersecting axes if two rcvolving quadric surfaces,and there by obtaining a new graphic method to find out thc projective position of special points of intersecting lines,and it presents the mathematical models for computer drawings更多还原
