利用一个新的视角考察了平面之中的曲线在平面双曲度量和欧氏度量下的对应不同的测地曲率.通过考虑对应几何量在这不同的度量下之间的关系,欧氏度量几何的一些经典结果被推广到双曲度量几何相应的情形.
This paper gives a new view of the geodesic curvature of curves in a plane with different metrics,namely,hyperbolic metric and Euclidean metric.Considering the relation of geometric quantities between different metrics,some classical results in Euclidean metric geometry in a plane will be extended to that of hyperbolic geometry.
