用去相关轨迹法研究了碰撞粒子在随机磁场中的输运。磁力线捕获的非线性效应被认为是与粒子碰撞。运行扩散系数的随机磁场和碰撞速度的统计参数的任意值确定。确定了磁力线俘获效应。发现了新的反常扩散机制。
The transport of collisional particles in stochastic magnetic fields is studied using the decorrelation trajectory method. The nonlinear effect of magnetic line trapping is considered together with particle collisions. The running diffusion coefficient is determined for arbitrary values of the statistical parameters of the stochastic magnetic field and of the collisional velocity. The effect of the magnetic line trapping is determined. New anomalous diffusion regimes are found.
