平面代数曲线的阶和级

Classes and orders of plane atgebraical curues

文章以二维复射影空间为论域。在考察一般代数曲线的阶和级以及它们之间的关系的基础上 ,推演出射影几何教程中关于二阶曲线与二级曲线的相互转化的理论。使建立这些理论的观点和方法更具有一般性。

This essay in concerned with two dimension of complex projection space. On the basis of exploring the general relation between curve classes and curve orders, the essay suggests a theory for the transformatron between order two curves and class two curves in a projection geometry course. Making the theory more universally applicable.
