查询词典 displacements

A "time-dependent relaxation" method is proposed to accurately implement given photospheric footpoint displacements and force-free conditions. The method is applied to analyzing the energy buildup of coronal magnetic fields, and the numerical results confirm the Aly conjecture (the magnetic energy of the force-free field is bounded above by the fully-open field energy), and extends it from fully-open to partially-open force-free fields.
