摘要

Abstract

Solar flares/CMEs,essential to understanding the energy conversion from magnetic energy to plasma's thermal,kinetic,and nonthermal energies,are the fundamental source of space weather disasters.The turbulence-induced dissipation-diffusion under different hydro-dynamic-kinetic coupled scales by considering the turbulence-resistance-induced self-generated organization and the turbulence-viscosity-induced self-feeding-sustaining,is far more significant than classical viscosity and resistivity,generating two fully coupled mixed dissipation processes.Here,we review the turbulent viscous dissipation and turbulent resistance dissipation during the fine-structure evo-lution process of fractal turbulent large temporal-spatial current sheet theoretical model from theoreyical,obser-vational,and simulation perspective.First,we summarize various classical large temporal-spatial current sheet theoretical models and introduce their research progress and applications in turbulence-induced viscous and resis-tive dissipation-diffusion fields.Then,the latest developments in turbulent dissipation are summarized.Finally,the discussion and outlook highlight several issues that need to be addressed urgently in the future research.
