Energy spectrum and mass composition of primary cosmic rays around the 'knee' in the framework of the model with two types of sources

Analysis of the experimental data on cosmic ray spectra in the framework of the proposed model with two types of sources leads to conclusion, that sources with particle generation spectral exponent p∼2.85 give the major contribution to the all-particle spectrum in the energy range 105-107 GeV. 'Fine structure' of spectrum around the 'knee' may arise due to presence of nearby supernova type source, accelerating particles up to the energies ∼3.104 ZGeV, if the energy output of such source is ∼2.1048 erg/source
