摘　　要：本文利用张量的基本概念讨论了切线坐标系的自然基矢量,求得切线坐标系中的速度分量,进而用微分变换的方法导出了主要由切线坐标表示的曲率半径公式。With the tensorial concept, the nature unit vector were discussed in the frame of tangeni coordination and the velocity components were obtained. Meanwhile,by the method of differetial transformation, curvature radii formula in the tangent coordination was deduced.

关 键 词：切线坐标系 自然基矢量 曲率半径
