Abstract
Assuming that supernova shocks accelerate Galactic cosmic rays and that the shock compression ratio is supernova remnant (SNR) age dependent, the source injection spectrum from an ensemble of SNRs is calculated by considering the SNRs age distribution in the galaxy. The calculated spectrum is used to obtain the cosmic-ray spectrum in the galaxy and the resulting diffuse gamma-ray spectrum is compared with the EGRET data. Some results on the observed cosmic-ray spectra are also discussed.
