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.

通过大规模模拟和航天器观测数据分析，研究了太阳和天体物理等离子体的各种活跃现象。我们在发电机过程产生磁场、恒星大气磁涌现、地表磁活动、稳定磁加热、爆炸耀斑触发、湍流重联、相对论重联、非热等领域取得了重要成果。粒子加速度等。
