摘要：
The latest NA49 results on fluctuations of multiplicity and average transverse momentum analyzed on an event-by-event basis are presented for central Pb+Pb interactions over the whole SPS energy range (20 A-158 A GeV). The scaled variance of themultiplicity distribution decreases with collision energy whereas the Phi(pT) measure of < p(T)> fluctuations is small and independent of collision energy. Thus in central Pb+Pb collisions these fluctuations do not show an indication of the critical point of strongly interacting matter.
