提出了一种新的方法来检测孤立的封闭流线在二维矢量场。该方法基于将2D矢量场变换为适当的3D矢量场的思想，使得检测2D中的闭合流线等同于在3D中相交某些流表面。与现有的方法相反，我们的方法不依赖于向量场的任何底层网格结构。我们证明了它的适用性和稳定性，通过应用到一个测试数据集。
We present a new approach to detecting isolated closed stream lines in 2D vector fields. This approach is based on the idea of transforming the 2D vector field into an appropriate 3D vector field such that detecting closed stream lines in 2D is equivalent to intersecting certain stream surfaces in 3D. Contrary to pre-existing methods, our approach does not rely on any underlying grid structure of the vector field. We demonstrate the applicability and stability by applying it to a test data set.
