摘　　要：本文讨论分层大气中孤立约束磁通量拱的二维静平衡位形．通量拱中的磁场初步假定为无力场，通过利用有限元计算方法，得到这个非线性自由边界问题的数值解．结果清楚地表明磁拱的内外场的耦合关系，并讨论了大气压力分布，尤其是大气标高对通量拱位形的影响．Two-dimensional equilibrium configuration of isolated magnetic flux arch confined in the stratified atmosphere was discussed in the present paper.The magnetic fields in the flux arch were assumed to be force-free as the first step.and the nonlinear problem with free boundary was solved numerically by the finite element method.The results showed clearly the coupling relation between inner field of magnetic arch and outer field of stratified atmosphere,and the influence of atmospheric pressure distribution,especially the scale height of atmospheric,on the configuration of magnetic arch was analyzed.
