论文摘要
我们通过使用\ textit {intiT {initU}测量在2017年7月26日的地球磁场中的磁层多轴任务的测量来介绍在单个湍流磁重新连接期间观察到的磁结构和相关能量耗散的首次统计研究，该结构是通过在磁性领域中识别出磁性的磁场或分类的，该结构是通过磁性静止的磁场来识别的。电流密度和血浆流。浆液的大小形成从子电子量表到离子尺度的衰减指数分布。大量电流板的存在与湍流重新连接过程中动态产生和浆液合并的物理形象一致。磁性结构是通过平行于局部磁场的电场进行明显的能量耗散的位置，而通过垂直电场的耗散占据了结构外部。显着的能量也从颗粒返回到田地。
We present the first statistical study of magnetic structures and associated energy dissipation observed during a single period of turbulent magnetic reconnection, by using the \textit{in-situ} measurements of the Magnetospheric Multiscale mission in the Earth's magnetotail on July 26, 2017. The structures are selected by identifying a bipolar signature in the magnetic field and categorized as plasmoids or current sheets via an automated algorithm which examines current density and plasma flow. The size of the plasmoids forms a decaying exponential distribution ranging from sub-electron up to ion scales. The presence of substantial number of current sheets is consistent with a physical picture of dynamic production and merging of plasmoids during turbulent reconnection. The magnetic structures are locations of significant energy dissipation via electric field parallel to the local magnetic field, while dissipation via perpendicular electric field dominates outside of the structures. Significant energy also returns from particles to fields.
