本文采用可连续变化撕裂模稳定性参数δ '的简单板系磁流体力学模型，探讨了磁岛的生长。除非系统接近边际稳定，否则重联由Sweet-Parker电流层控制，其形成是磁岛平衡固有的奇异结构的结果。
The growth of magnetic islands is explored using the magnetohydrodynamic model in a simple slab system in which the value of the tearing mode stability parameter Delta' can be varied continuously. Unless the system is close to marginal stability reconnection is controlled by Sweet-Parker current layers, whose formation is a consequence of the inherent singular structure of magnetic island equilibria.
