1·Some geometric data of ellipse in hyperbolic space are considered, such as set inclusion, arc length, geodesic curvature, curvature, area and total curvature.

在双曲空间中，考察椭圆的包含关系，对弧长元素、测地曲率、曲率、面积及全曲率等几何量做出细致考察。

2·From the changing trend of the curvature of adjacent elements, the general trend of geodesic lines can be determined.

从相邻单元曲率的改变趋势，能够判别出测地线的大致走向。
