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.

利用较为简单的仿真模型，研究了磁约束等离子体中电子/离子温度梯度驱动的多尺度湍流，研究了扰动时间序列数据中几种统计量与扰动间歇性和湍流结构之间的关系等紊流等离子体的统计特性。还发现，扰动和湍流结构的间歇性可以通过在某一点上获得的统计量来识别，例如相关维数。
