2) writhing number
绞拧数
1.
In order to solve the matching problem of 3-D coupler-curves, the substructures of coupler-curves were classified into different equivalence classes based on writhing numbers,which is borrowed from knot theory and can describe characters of spatial curves to some extent.
为了解决空间连杆曲线与预定轨迹的匹配问题,利用纽结理论中反映空间曲线几何形态的绞拧数作为指标,将曲线各子段对分成若干个等价类,对每个等价类中各曲线子段对进行刚体变换而近似匹配,通过对刚体变换进行聚类分析得到曲线的匹配关系,从而得到两者的相似度。
3) left regular lay

4) No Twist/ Do not Twist
