| Outline of Final Research Achievements |
The galactic cosmic ray (GCR) observed at the Earth reveals various physical phenomena in the origin of the galactic cosmic rays (supernova remnants) and/or in the Galaxy. In order to obtain the crucial key for understanding the propagation of the GCRs in the Galaxy and an anomalous increase of the GCR positrons, we have developed the numerical model of the GCR propagation in the Galaxy by considering the discreteness of GCR sources and an anisotropic diffusion.
