悬链面是微分几何中很重要的一种曲面.主要借助曲面的第一、第二类基本量及曲面上的各种曲率用各种方法来研究悬链面上各种曲线,例如渐近线、曲率线、测地线,得出曲线的形状、方程和曲线具有的一些性质.
Catenoid is a very important curve in differential geometry. In this paper, we research various curves, such as the asymptote, lines of curvature and geodesic. Then we obtain the shape, equation and some property of the curves using the various curvatures.
