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.The dynamical behaviour of the one-dimensional complex Ginzburg-Landau equation （CGLE） with finite system size L is investigated, based on numerical simulations.
