The correlation characteristics of the fine-scale fluctuations of the temperature of relic radiation created by pregalactic adiabatic inhomogeneities of cosmic plasma in the period of the recombination of hydrogen are calculated. It is shown that for the density of the cosmological "hidden mass" 10 or 100% of the critical one the r.m.s. value of variations of the temperature of the microwave radiation is equal to 8×10-6(1+zs) and 4×10-6(1+zs) respectively, where zs is the moment of the onset of the nonlinear regime of perturbations. The characteristic correlation scale of the fluctuations of temperature is equal to 10-30 arc minutes.
