摘　　要：本文提出了一种球面上基本几何元素的园弧投影变换方法,并建立了三轴及对应的二轴园弧投影体系。然后,系统地阐明了点、各种球面曲线以及球面的园弧投影方法和性质。这样。This paper presents a method of arc projective transformation of the fundamental geometric ele- ments on a sphere,and sets up an are projective system for three axial and two axial correspondently. It also expounds such ar projective methods and properties for points various spherical curves and sphere systematically.So a new tool for the research of sphere problems has been given

关 键 词：基本几何元素 球面 圆弧投影 投影模型
