论文摘要
我们研究了漂移运动的影响以及银河风对银河系中宇宙射线传播的影响。我们采用简化的磁场模型，该模型基于（且类似于）用于银河磁场的Jansson-Farrar模型。允许扩散是各向异性的。使用一组随机微分方程来数值求解相关方程。包括漂移和银河风会大大缩短宇宙射线的停留时间，即使对于中等风速
We study the effects of drift motions and the advection by a Galactic wind on the propagation of cosmic rays in the Galaxy. We employ a simplified magnetic field model, based on (and similar to) the Jansson-Farrar model for the Galactic magnetic field. Diffusion is allowed to be anisotropic. The relevant equations are solved numerically, using a set of stochastic differential equations. Inclusion of drift and a Galactic wind significantly shortens the residence time of cosmic rays, even for moderate wind speeds
