在强磁化天体物理等离子体环境中，磁场重联被认为是能量快速释放和粒子碰撞的主要过程。目前，人们对相对论性磁重联有着浓厚的兴趣，因为它可能为强磁化天体物理系统中的高能粒子加速和辐射提供新的解释。本文综述了磁主导区中粒子加速和重联物理的最新进展。更多的讨论集中在粒子加速，幂律形成以及重联率问题的物理。此外，我们还对下一步研究重联加速机制和动力学物理进行了展望。
Magnetic reconnection in strongly magnetized astrophysical plasma environments is believed to be the primary process for fast energy release and particle energization. Currently there is strong interest in relativistic magnetic reconnection, in that it may provide a new explanation for high-energy particle acceleration and radiation in strongly magnetized astrophysical systems. We review recent advances in particle acceleration and reconnection physics in the magnetically-dominated regime. More discussion is focused on the physics of particle acceleration, power-law formation as well as the reconnection rate problem. In addition, we provide an outlook for studying reconnection acceleration mechanisms and kinetic physics in the next step.
