  CMBR distortion concerned with recombination of the primordial plasma is
calculated in frequency band from 1 GHz to 100 GHz in the frame of the standard
cosmological model for different values of cosmological density parameters:
nonrelativistic matter density $\Omega_m$ and baryonic matter density
$\Omega_b$. Comparison of these results with observational data which will be
obtained from planned experiments may be used for independent determination of
the cosmological parameters $\Omega_m$ and $\Omega_b$.
