摘要
本文目的是给出空间Ferguson三次参数曲线及Hermite、Ball、Be'zier、Timmer三次参数曲线上无重点和逗留点的两个定理,并给出它们的曲率和挠率计算公式。
the purpose of this paper is to prove the thorems which has no singularity points and staying points about Ferguson Curves of degree 3 in space. In addition, we give the Calculation formular of Curvature and totion.
