论文摘要
航天器的数据显示，在薄磁尾电流板中，横向到磁场的非均匀的双极电场横向导致强烈的EXB速度剪切和非甲状腺素颗粒分布。 EXB漂移远远超过了磁磁漂移，并驱动局部磁场逆转区域的较低杂种波，这非常适合重新连接所需的异常耗散。它还揭示了嵌入在电流密度中的子结构，表明形成了非理想的电流板。
Spacecraft data reveals a nonuniform ambipolar electric field transverse to the magnetic field in a thin magnetotail current sheet that leads to intense ExB velocity shear and non-gyrotropic particle distributions. The ExB drift far exceeds the diamagnetic drift and drives lower hybrid waves localized to the magnetic field reversal region, which is ideally suited for the anomalous dissipation necessary for reconnection. It also reveals substructures embedded in the current density, indicating the formation of a non-ideal current sheet.
