磁通线切割（相邻非平行涡旋的交叉和交叉连接）被认为是纵向磁场中载流II型超导体稳态耗散的一种机制。本文提出了一个具体的理论磁通线切割模型，它产生一个恒定的稳态电场中载流，理想的，II型超导板在纵向场。假设模型由不同角度的平行涡面组成，这些涡面在磁通线切割发生的区域之间周期性地来回穿梭。由此产生的宏观电流和磁通密度分布的计算。该模型产生了一个非线性的电压-电流特性和纵向顺磁矩。
Flux-line cutting (intersection and cross-joining of adjacent nonparallel vortices) has been suggested as a mechanism for steady-state dissipation in current-carrying, type II superconductors in longitudinal magnetic fields. In this paper a specific theoretical flux-line-cutting model is proposed which generates a constant steady-state electric field in a current-carrying, ideal, type II superconducting slab in a longitudinal field. The assumed model consists of parallel vortex planes at different angles which periodically shuttle back and forth between the regions in which flux-line cutting occurs. The resulting macroscopic electric current and magnetic flux density distributions are calculated. The model yields a nonlinear voltage-current characteristic and a longitudinal paramagnetic moment.
