摘要
利用特征根对一般二次曲面的圆截面的存在性和方程进行了比较深入的研究,推导出6种常用二次曲面的圆截面的方程,并证明了2种常用二次曲面不存在圆截面。
The study on the existence and the equation of circle section of quadric surface was made by using the characteristic root.Six equations for the circle section of quadric surface were deduced,and that two quadric surfaces do not have circle sections was proved.
