克雷格和亨顿[Astrophys. J. 450，280（1995）]中的方法，以包括流体的有限粘度和磁场和速度场中的非平面分量的存在。结果表明，快速重联可以实现足够小的值的运动粘度。特别是，耗散率是持续的强放大平面磁场分量平流向中性点。相比之下，非平面场分量平流没有放大，所以耗散能量在缓慢的斯威特帕克率。
The exact planar reconnection analysis of Craig and Henton [Astrophys. J. 450, 280 (1995)] is extended to include the finite viscosity of the fluid and the presence of nonplanar components in the magnetic and velocity fields. It is shown that fast reconnection can be achieved for sufficiently small values of the kinematic viscosity. In particular, the dissipation rate is sustained by the strong amplification of planar magnetic field components advected toward the neutral point. By contrast, nonplanar field components are advected without amplification and so dissipate energy at the slow Sweet–Parker rate.
