摘要
无力场被广泛用来模拟太阳活动区的强磁场,本文从Bernstein能量原理出发,导出了无力场能量原理的普遍形式,并给出了若干稳定性的充分条件,它们可方便而有效地对无力场进行稳定性判断。
Force-free magnetic fields have been widely applied to simulating strong magnetic fields in solar active regions. Based on the Bernstein energy principle, this paper derives a general form of energy principle for force-free fields and presents several sufficient conditions for stability, which may be used to conveniently and effectively form a judgement on the stability of force-free fields.
