摘要：

The temporal evolution of Alfven intermittent turbulence in cosmic plasmas is studied. The chaotic dynamics of a driven-dissipative Alfven system is determined by numerically solving the derivative nonlinear Schrodinger equation in the low-dimensional limit. Two types of Alfven intermittent turbulence are identified: Pomeau-Manneville intermittency and crisis-induced intermittency. The significance of this theory for Alfvenic intermittent turbulence observed in the solar wind is discussed.
