Abstract: This paper supposes that all cosmic ray (CR) particles of energy below 3×1018eV mainly originate and accelerate in an individual explosion of the supernova (SN) in the Galaxy; with the use of an isotropic diffusion propagation model, the non-steady state density distribution of Iron nuclei is investigated. Considering the effect of extragalactic CRs and the variety of the galactic CR nuclei, the statistic model of galactic CRs with a reasonable distribution of the galactic SNs in space and time can account for the spectrum of CRs in the energy range of 1012-1020eV quite well.
