摘要
在研究磁力线脚点缓慢运动引起的无力场的准静演化时,考虑等离子体运动对演化的影响是非常重要的。本文以基本的MHD方程为依据,给出一种二维无力场进行小扰动准静演化时求等离子体位移的方法,并对一个二维无力磁拱模型的脚点运动引起的无力场演化和等离子体运动进行了具体的研究。
Based on the full set of MHD equations, a method to find the displacement of plasma is developed for a two dimensional force free field slightly perturbed in quasi-static evolution, and applied to the evolution of a magnetic arcade by a slow motion of its footpoints.
