| 摘 要： | 本文从能量原理出发，对无力场稳定性进行了研究，给出了一般情形下无力场稳定性的充要判据。它可以把线性无力场稳定性判据作为特例包括在内。还对Ｋｒｕｇｅｒ给出的一个充分判据作了进一步的探讨，对无力场稳定性的物理图象也作了讨论。

| Abstract: | Based on the Bernstein energy principle,the stability of force-free fields is studied,and the sufficient-necessary criteria for the stability of linear and nonlinear forcefree fields is derived.from which the well-known criteria form for linear force-free magnetic fields can be easily deduced.In this paper,the sufficient criteria for the stability of nonlinear force-free fields given by Kruger is carefully studied and the physical explanation is discussed,too. |
