Based on arc-length parametrical curves,we discussed the geometrical properties for planar regular local convex curves,proved that the planar local convex curves locates on the right semi-closed(left semi-closed)plane of tangent line at arbitrary point on the curve,and derived a few important properties at any point on the curve.
基于弧长参数曲线的性质,讨论了平面正则参数局部凸曲线的性质,证明了平面正则参数局部凸曲线在曲线任意一点的切线的闭左半平面(闭右半平面),导出了局部凸曲线在逗留点处的几个重要性质。
