摘要
本文研究了空间曲线曲率中心轨迹的曲率和挠率,导出其曲率、挠率与空间曲线的曲率、挠率的关系式,为深入研究曲率中心轨迹的结构奠定一定基础.
This paper studies space curves trajectory curvature center of curvature and torsion, export of its curvature, torsion and the curvature and torsion of space curves of the relationship, for in - depth study of the structure of trajectory curvature centers certainly has laid the foundation.
