| Research Abstract |
By large-scale simulations and spacecrafts' observational data analysis, various active phenomena of the solar and astrophysical plasmas were studied. We obtained important results in the fields of generation of magnetic field by the dynamo process, magnetic emergence to the stellar atmosphere, magnetic activities on the surface, the steady magnetic heating, the triggers of explosive flares, turbulent reconnection, relativistic reconnection, non-thermal particle accelerations and so on.
