摘要：
This review addresses the issue of cosmic rays acceleration in supernova remnants in connection with the amplification of magnetic fluctuations. Possible scenarios of magnetic field amplification are discussed with a special emphasise on the contribution of instabilities driven by cosmic ray currents as well as the saturation process and the properties of the turbulence. We scan acceleration efficiencies of different class of supernova remnants and there respective contribution to the cosmic ray spectrum. We finally review some aspects of the recent numerical effort in modelling the magnetic field amplification in supernova remnant shocks.
