    Abstract
  • Magnetic reconnection is a crucial energy conversion process in plasmas, and it is important to study the forms of energy conversion and their distribution in this process. Previous research has focused mainly on the energy fluxes in symmetric reconnection, while the study of asymmetric reconnection at the Earth’s magnetopause, especially in terms of statistical analysis of multiple events, has been limited. Therefore, 10 magnetic reconnection events at the magnetopause observed by MMS satellite that passed through the electron diffusion region were used for analysis . Found that the energy flux distribution varies among different events. However, in most of the events, the ion enthalpy flux is the dominant, followed by the Poynting flux. The ion heat flux is slightly smaller than the Poynting flux, and the ion kinetic energy flux, electron enthalpy flux and electron heat flux account for less than 10% of the total energy flux. By normalizing the events, obtained the relationship diagram of different energy fluxes in the L and M directions with the magnetic field and ion velocity in the L direction, and analyze the characteristic distribution of each energy flux.
