关于椭球面的平截线的探讨

The process about the curve of a plane section on the ellipsoid

利用坐标变换把平面方程化成新坐标系下的某一坐标平面的方程,从而把一般的平截线转化为新坐标系下的坐标平面截线,而椭球面的坐标平面截线知识是熟知的,这样问题便得以解决.

In this article, the author utilizes coordinate tranformation to change a plane equation into a equation of certain a coordinate plane of the new coordinate system, such that the curve of a general plane section is changed into the curve of a coordinate plane section under the new coordinate system, but the knowledge of the curve of coordinate plane section is known very well,so the question is solved on the coordinate plane.
