  Spectrum and chemical composition of cosmic rays accelerated in supernova
remnants are studied on a basis of kinetic approach. The cosmic ray transport
equation with the Bohm diffusion coefficient has been numerically solved
self-consistently with gas dynamic equations for the underlying flow.
Comparison with observational results gives some indications that galactic
cosmic rays are produced by supernovae shocks which expanded in the relatively
low temperature partially ionized interstellar medium.
