It is also found that the wave amplitude at resonant place increases linearly with time and the slope is proportional to Alfven wave speed, inverse proportional to loop length and independent of driven frequency. 共振磁力线振幅随时间线性增加,增加的斜率正比于Alfvn波速,反比于冕环长度,与驱动频率无关。
It is shown that only with the Alfven speed higher than the sound speed upstream can a fast shock and a slow shock achieve their spatial connection and temporal evolution via intermediate shocks. 指出只有当上游背景阿尔文波速超过声速时,才有可能通过中间激波实现快、慢激波之间的空间连接和时间演化。
The Alfven layers are located in the narrow region where the initial flow velocity equals to the local Alfven speed and move away from the reconnection region slowly as the island develops. 共振层位于初始流速度等于当地Alfven速度很窄的范围内。随着磁岛的发展,这对共振层慢慢远离重联分离线。
