摘　　要：理想元素是欧氏几何过渡到射影几何的桥梁,是射影几何的基石。由于理想元素的"引入,"在欧氏几何的基础上开辟出一块全新的几何园地,使高等几何充满了创新意识和思想,其中理想元素还充满了创造性地综合应用。The ideal element is a bridge that Euclidean space geometry transits to projection geometry,a cornerstone in project geometry.Introduction of the ideal element opens the brand-new geometry field on the foundation of Euclidean space geometry,making higher geometry innovative and thoughtful.This paper is to present its application in higher mathematics.

关 键 词：理想元素 极限 中心投影
