利用脐点的性质研究欧氏空间中二次曲面的圆截口问题
Research of Circle Section Quadric Surface in the Eududean Spure by the properties of the Umbilic Points
摘要
Abstract
In this paper, we make use of the properties of the umbilic to research circle Section question of quadric in 3-dimensional euclidean space. We give the equations of these circle sections.关键词
