CR with energy 10 -10 eV is formed by numerous distant sources. It means that the contribution of these sources to the observed flux may be evaluated in the framework of the steady-state approach. Using results of Lagutin et al. (2001a), in paper Lagutin et al. (2005), the total flux J'D of the particles of type i from all distant (r > 1 kpc) sources have been presented in the form
where vi is a particle velocity, C0i is a constant evaluated via fitting of experimental data.
The contribution J'l (E, r < 1 kpc) of the nearby or local (r < 1 kpc) relatively young (t < 105 years) sources defines the spectrum in the high energy region and, as it was shown in papers Lagutin et al. (2001d), Lagutin and Uchaikin (2003), provides the knee in the spectrum of galactic CR observed on the Earth:
4n j where rj, tj are the coordinate and the age of the source j, n (rj, tj, E) is the CR
concentration from this source.
The similar separation of the flux into two components with significantly different properties is frequently used in the CR studies. However, the presence of the large free paths of the particles (the 'Levy flights') in considered model leads to the introduction of the third component. This third component is formed by the particles, which pass a distance between an acceleration site of a source and solar system without scattering. The flux of non-scattered particles J'njs is determined by the injected flux ^ S^E~P and the 'Levy flight' probability P(> r,E). Taking into account that for the particle with energy E the probability
Lagutin et al. (2005) assumed that this component defines the spectrum in the
