| Research Abstract |
The statistical characteristics of turbulent plasma, such as the relations of several statistics obtained from time series data of perturbations with intermittency of perturbations and turbulent structures, were investigated for multi-scale turbulence driven by electron/ion temperature gradient in magnetic confinement plasma with relatively simple simulation models. It was also found that intermittency of perturbations and turbulent structures could be identified by the statistics obtained at one point, such as the correlation dimension.
