Inclusive cross-sections for gluon jet production are studied numerically in the perturbative QCD pomeron model for central collisions of identical nuclei at high energies. Two forms for the inclusive cross-sections, with and without emission from the triple pomeron vertex, are compared. The difference was found to reduce to a numerical factor 0.8$\div$ 09 for momenta $k$ below the saturation momentum $Q_s$. Above $Q_s$ no difference was found at all. The gluon spectrum was found to be $\sim A$ for $k<Q_s$ and $\sim A^{1.1}$ for $k>Q_s$. At large $k$ the spectrum falls as $1/k^{2.7\div 3.3}$ flattening with energy. The multiplicities are proportional to $A$ with a good precision. Their values are high amd grow rapidly with energy.
