  This article describes calculations of the yield ratio of anti-particles to
the yield of particles ($\bar{p}/p$,
$\bar{d}/d$,$\overline{^{3}\mathrm{He}}$/$^{3}$He) in proton-proton and
nuclear-nuclear interactions using the self-similarity parameter in the central
rapidity region. The used approach is based on the study of relativistic
nuclear interactions in the four-velocity space. The results of the
calculations are compared with the existing experimental data in a wide
center-of-mass energy range ($SPS$, $RHIC$, $LHC$). Within this approach the
inclusive spectra of pions and kaons and ratios of their yields in $pp$
collisions have been successfully described earlier.
