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.

提出计算无力磁场的"时变松弛"方法，能精确实现光球足点位移和无力条件；采用该方法分析日冕磁场的剪切储能，验证了Aly猜想（无力场磁能以全开放场磁能为上限），并将该猜想由全开放无力场推广至部分开放无力场。

FR conjugate gradient methods with perturbations are proposed. The global convergence property of the first method is proved under the condition of main directions' sufficient descent. Whereas, in the proof of the convergence for the other two methods, we only need main directions' descent. Importantly and quite interesting, boundedness conditions such as objective function being bounded below, boundedness of level set are not needed. Chapter 5 presents a version of Dai-Yuan conjugate gradient method with perturbations.
