结合模拟研究和实验观察，解释了等离子体湍流和输运理论的进展，重点是非线性不稳定机制、与介观尺度结构的相互作用，如纬向流、转变和统计特性。例子包括中尺度波动筛选的湍流波动、不同类别湍流之间的非线性相互作用引起的湍流转变、以及统计描述和转变概率。解决了全局等离子体结构和湍流的自我调节机制，并解决了对改进约束状态的生成的见解。对湍流和结构形成的理解的这一进展说明了等离子体物理学作为现代物理学的一个重要分支的进步。
Progress in the theory of plasma turbulence and transport, in collaboration with simulation research and experimental observations, is explained, putting emphasis on the nonlinear instability mechanisms, interaction with meso-scale structures such as zonal flow, transition, and statistical properties. Examples include turbulent fluctuations screened by meso-scale fluctuations, turbulence transition induced by nonlinear interplay between different classes of turbulence, and statistical description and transition probabilities. The self-regulating mechanisms of global plasma structure and turbulence are addressed, and insights into the generation of improved confinement states are addressed. This progress in the understanding of turbulence and structure formation illustrates the advancement of the physics of plasma as an important branch of modern physics.
