This paper reviews the present state of the problem of the origin of cosmic rays. Primary attention is paid to galactic diffusion models with a halo, and questions of cosmic-ray chemical composition, electron component, and synchrotron galactic radioemission. The authors' conclusion is that models with a large halo with a characteristic cosmic-ray age ${T}_{\mathrm{cr}}\ensuremath{\sim}{10}^{8}$ years are confirmed by radio data, and at least do not contradict the information on cosmic-ray… Expand
