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.

针对磁约束等离子体中电子/离子温度梯度驱动的多尺度湍流，研究了湍流等离子体的统计特性，例如由扰动的间歇性和湍流结构的扰动时间序列数据获得的多个统计量之间的关系，并用相对简单的方法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。模拟模型。研究还发现，扰动和湍流结构的间歇性可以通过某一点获得的统计数据（例如相关维数）来识别。
