摘要:
It can be shown that for linearly unstable magnetohydrodynamic modes near the threshold of linear instability, the mode amplitudeA(t) evolves according to ∂2A/&Lgr;t2=&lgr;2A+&agr;A3which can lead to nonlinear stabilization, explosive instability, or eventual decay, depending on the sign of &agr;. This is demonstrated explicitly for them=1 kink modes in a sharp boundary plasma pinch.
