【摘要】 The dynamical behaviour of the one-dimensional complex Ginzburg-Landau equation(CGLE) with finite system size L is investigated,based on numerical simulations.By varying the system size and keeping other system parameters in the defect turbulence region(defect turbulence in large L limit),a number of intermittencies new for the CGLE system are observed in the processes of pattern formations and transitions while the system dynamics varies from a homogeneous periodic oscillation to strong defect turbulence.
