本文讨论了空间曲线任意片段的扭曲数的定义和计算。该方法基于用测地线闭合切线指标。这是一种将痛苦与高人联系在一起的关系？研究了开曲线上的积分。以单螺旋和双螺旋形状为例。
The paper deals with the definition and computation of the writhingnumber of an arbitrary fragment of a space curve. The approach is basedon closing the tangent indicatrix with a geodesic. A relationship connectingthe writhe with the Gau? integral over the open curve is studied.Single and double helical shapes are presented as examples.
