摘要
由于平行公理不同,导致罗氏平面直线与欧氏平面直线有很大差异。本文利用Cayley-Klein模型探讨罗氏平面直线的特性。
Due to different axioms of parallels, there are great differences betweenLobatchevskian plane straight line and Euclidean plane line. This paper applies the Cayley- Kleinmodel to the study of the special features of the Lobatchevskian plane line.
