摘要：

In the present article previous work is complemented by investigating analytically the field line random walk in partially turbulent magnetic fields. By using the well-established model of two-dimensional turbulence with a general spectrum at large scales, we compute the field line diffusion coefficient for all length scales. This work will also clarify some confusion about the superdiffusive and diffusive regimes discovered earlier. (C) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
