论文摘要
磁重新连接是一种普遍存在的等离子体过程，其中相反的磁场线断裂并重新加入，从而改变了磁场拓扑。重新连接生成磁岛：由磁场线包围并通过重新连接点隔开的区域。正确识别这些特征对于了解血浆的颗粒加速度和整体行为很重要。我们提出了一个基于轮廓树的可视化，以在二维（2D）磁重新连接模拟中对岛屿的鲁棒和客观识别和重新连接点。这种可视化在简单的模拟中的应用显示出了以前没有报道的物理现象，从而对磁重新连接有了更全面的了解。
Magnetic reconnection is a ubiquitous plasma process in which oppositely directed magnetic field lines break and rejoin, resulting in a change of the magnetic field topology. Reconnection generates magnetic islands: regions enclosed by magnetic field lines and separated by reconnection points. Proper identification of these features is important to understand particle acceleration and overall behavior of plasma. We present a contour-tree based visualization for robust and objective identification of islands and reconnection points in two-dimensional (2D) magnetic reconnection simulations. The application of this visualization to a simple simulation has revealed a physical phenomenon previously not reported, resulting in a more comprehensive understanding of magnetic reconnection.
