摘　　要：采用实际的磁尾位型,利用数值模拟方法研究磁层亚暴过程中高速流分布。结果表明垂直磁场的高速流主要分布在电流片内,范围在|Z|<0.25RE;平行磁场高速流分布区域在两个区域较大,一个是距离地球较近的磁场较强的区域,另一个是距离等离子体片较近磁场较强的区域。The high-speed flow distribution during the magnetospheric substorm is investigated using the numerical simulation with the realistic magnetotail geometry.The results indicate that the high-speed flows perpendicular to the magnetic field are mainly distributed in the current sheet in the range of ｜Z｜0.25RE,and that parallel to the magnetic field are mainly distributed in two areas： the strong magnetic field areas in the Near-Earth and in the near the plasma sheet.
