Add to ORKGThe energetic requirements for cosmic-ray acceleration are evaluated and the abundances of various elements, electrons, and positrons, are reviewed. Various models for cosmic-ray production involving different aspects of the supernova process are evaluated. The difficulties in theories which make pulsars the main source of cosmic rays are stressed. (4 refs)
