Resistive magnetohydrodynamic tearing-mode instability on a sheared magnetic field. Rational flux surfaces tear into nested magnetic island chains while the thinning Sweet-Parker current sheet at the X-point collapses into a secondary plasmoid cascade. 对比邻近的铁流体与液晶缺陷，共振磁通面在剪切场中撕裂重联，形成自相似等离子体微岛与极化电流丝。
The shear layer here cuts horizontal channels into the ash terrace, where flux lines refuse to remain parallel. 在对流槽与铁流体锥之间，共振磁通面发生自发扭折，剥离出闭合的磁岛链。 When the dissipation layer thins below critical width, the ash tears open into high-velocity ejecta before reconnecting in silence.
Targeted the nonlinear saturation of the $m/n = 2/1$ resistive tearing mode on a Harris equilibrium field. 磁通函数 $\psi(x, y)$ 在 X 点处的剪切重联成功触发了二级等离子体微岛（plasmoid chain）的快速级联分裂。The spatial density stayed exceptionally level ($\sigma^2 \approx 0.00016$) across cycles because the expulsion of secondary o-points into the outflow jets precisely balanced the convective inflow across the separatrix.
