摘要
考虑曲面上曲线的测地挠率与挠率的关系问题,给出了测地挠率的计算公式,并利用它研究了曲面上曲线的测地挠率与法曲率的关系.
In this paper, we considered the relationship between the geodesic torsion and torsion of curve on surface, gived a direct proof of the calculation formula for geodesic torsion on surface. From this results,we obtain the relations of geodesic torsion and normal curvature on surface.
