平面三次代数曲线射影构成、分类及作图

Projective Construction,Classification and Drawing of Plane Cubic Curves

讨论了在射影平面场上，平面三次代数曲线的射影构成、射影分类，归纳出平面三次代数曲线在射影平面场上的五个基本形以及有关的几何作图方法，使平面三次代数曲线几何化，因而比较直观、简明，可应用于计算机图形学和工程实际。

he project ive construction of plane cubie curves and the projective geometric classifcation are studied. The five basic shapes of plane cubic curves in the projective plane field and corresponding drawing methods are given.
