摘要
本文从解析几何的角度，研究了工程图学中“形”与“数”的对应关系，给出了具有公共对称面的两回转面在公共对称面上投影的数字表达式和特殊点坐标的计算公式，为设计会图软件提供了条件；分析了交线投影的弯曲趋势及其与回转面几何尺寸的关系，找到了满足蒙若定理的投影表达式。
This artical studied the relctian of'shape'and'figure'in enginecring graphics from the en gle of analytic geometry.It granted the mathematics expression two surface of revolution that have the relation of common symmetry projectin common symmetry and the calculated formula of specific point's coordinate.It granted material for designing graphic software.It analysted the relation of bend ing tend of the interlaced line's projection and revolute surface.It found the projective expression that content the Meng Ruo theorem.
