摘要
给出一个研究性学习案例.通过研究性学习,对等距螺线进行推广,得出球面螺线、椭球面螺线、单叶双曲面螺线等方程,并在Matlab上实现.通过曲线拟合给出一般旋转曲面螺线的绘制,并用一个"帽子型"螺线加以说明.
This paper is about examples of enquiry learning.The circular helix,spherical helix,ellipsoidal helix and hyperbolical helix,etc.,are presented and are plotted by MATLAB.Through curve fitting,general rotating surface helix is presented and illustrated by a ＂cap＂ helix.
