论文摘要
磁性绕组是基础磁性螺旋性并测量磁场线的纠缠的基本拓扑数量。像磁性螺旋一样，磁绕组也是理想磁流失动力学的不变性。在本文中，我们详细描述了磁绕组描述的描述，如何计算它以及如何相对于螺旋性解释它。我们展示了磁绕组如何提供对磁场（开放或封闭）的清晰拓扑描述，并举例说明磁绕组和螺旋的行为如何不同，从而揭示了有关基础磁场的不同和无能的信息。
Magnetic winding is a fundamental topological quantity that underpins magnetic helicity and measures the entanglement of magnetic field lines. Like magnetic helicity, magnetic winding is also an invariant of ideal magnetohydrodynamics. In this article we give a detailed description of what magnetic winding describes, how to calculate it and how to interpret it in relation to helicity. We show how magnetic winding provides a clear topological description of magnetic fields (open or closed) and we give examples to show how magnetic winding and helicity can behave differently, thus revealing different and imporant information about the underlying magnetic field.
