摘要：
We examine the dynamical roles of nonattracting chaotic sets known as chaotic saddles in an Alfven wave system described by the driven-dissipative derivative nonlinear Schrodinger equation. These Alfven chaotic saddles have gaps which are filled at the onset of chaos via a saddle-node bifurcation and at a chaotic transition via an interior crisis. It is shown that after an interior crisis an Alfven chaotic attractor consists of two chaotic saddles connected by a set of coupling unstable periodic orbits.
