离子撕裂模式被认为是唯一的机制，能够启动重联过程中的平衡等离子体片的规模大大超过离子拉莫尔半径。本文简要回顾了撕裂模不稳定性的线性理论，允许其发展的开始被确定。结果表明，撕裂模在非线性阶段的爆炸性增长是一致的带电粒子加速的动力学和磁尾中的磁场变化和等离子体流动的行为。本文还讨论了由于撕裂模的发展而形成的尾结构。
The ion tearing mode is considered as the only mechanism capable of initiating reconnection processes in the equilibrium plasma sheet whose scale considerably exceeds the ion Larmor radius. The paper gives a brief review of linear theory of the tearing mode instability that allows the onset of its development to be determined. It is shown that the explosive growth of the tearing mode in a nonlinear stage is consistent with the dynamics of charged particle acceleration and the behaviour of the magnetic field variations and plasma flow in the magnetotail. The tail structure formed, as a result of the development of the tearing mode, is also discussed.
