摘要:

本文研究了代数曲线和曲面奇点处曲率的计算问题。我们的想法是将问题转换为计算与原始曲线和曲面在奇点处相交的相应常规参数化曲线和曲面的曲率。为平面曲线、空间曲线和曲面的三种情况分别提出了三种算法。

英文摘要:

In this paper, we study the computation of curvatures at the singular points of algebraic curves and surfaces. The idea is to convert the problem to compute the curvatures of the corresponding regular parametric curves and surfaces, which have intersections with the original curves and surfaces at the singular points. Three algorithms are presented for three cases of plane curves, space curves and surfaces.
