摘　　要：宇宙线从源产生后传播到地球要和星际介质、磁场和辐射场等发生相互作用,它把天体物理源、星际空间环境等因素都联系起来,是获取天体物理信息的重要手段之一,因此探索宇宙线的传播模式是非常有意义的。Cosmic rays are the high-energy charged particles from space, which can provide high-energy material samples and is an important tool to study the cosmos space environment. Cosmic rays are one of important methods to obtain astrophysical information. The astrophysics-sources, interstellar space environments and other factors can be linked by cosmic rays interacting with interstellar matter, magnetic field and radiation field during the propagating from producing-source to earth. The propagation of cosmic rays in Galaxy is extremely complicated therefore building different models needed to simplify the propagation problems.Cosmic rays; propagation; model
