  It is shown that in central collisions of $^{197}$Au nuclei with heavy
emulsion nuclei at 11.6 $A$GeV/c two-particles pseudorapidity correlations for
produced particles in terms of correlation functions demonstate predominantly
long-range behaviour in contrast to nucleon-nucleon interactions. The
experimental data are compared with calculations based on the FRITIOF-M model
and the model of independent emission of particles.
