螺旋角的广义定义及其应用

Generalized Definition of Helical Angle and It's Applications

提出的速度法给出了螺旋线的螺旋角的广义定义。该定义对任意形体上的螺旋线均适用。给出了通常几种情况下螺旋线的螺旋角公式，并对球面、锥面及平面的等螺旋角螺旋线问题进行了讨论。

Based on“velocity method”proposed by authors,this paper presents a generalized definition of belieal angle,which is applicable to the spiral on the surface o f any geometric shapes. The formulae of belieal angles are given in general case,and the problems of equal belieal angle spiral on sphere, cone and plane are discussed for practical applications.
