论文摘要
磁重新连接已在完全离子化的等离子体中进行了深入研究。但是，在天体物理环境中，等离子体通常会部分电离。中性颗粒与离子化等离子体之间的相互作用可能会强烈影响重新连接机制。我们从理论，数值，观察和实验的观点中回顾了不同环境中部分电离等离子体中的磁重新连接。我们专注于使磁重新连接足够快的机制，以便与观测值进行比较，尤其是在低太阳大气中的重新连接事件上。还讨论了部分电离低太阳大气中重新连接过程的加热机制和相关的观察证据。我们描述了弱离子化的天体物理环境中的磁重新连接，包括星际培养基和原始磁盘。我们介绍了有关部分电离等离子体实验实验中快速重新连接的最新成就。
Magnetic reconnection has been intensively studied in fully ionized plasmas. However, plasmas are often partially ionized in astrophysical environments. The interactions between the neutral particles and ionized plasmas might strongly affect the reconnection mechanisms. We review magnetic reconnection in partially ionized plasmas in different environments from theoretical, numerical, observational and experimental points of view. We focus on mechanisms which make magnetic reconnection fast enough to compare with observations, especially on the reconnection events in the low solar atmosphere. The heating mechanisms and the related observational evidence of the reconnection process in the partially ionized low solar atmosphere are also discussed. We describe magnetic reconnection in weakly ionized astrophysical environments, including the interstellar medium and protostellar disks. We present recent achievements about fast reconnection in laboratory experiments for partially ionized plasmas.
