摘要：

Data on phi-production obtained by the CERN NA49 experiment for central Pb+Pb collisions at 158 GeV/u are presented. Compared with pp interactions the phi-yield shows substantial strangeness enhancement: the phi/pi ratio is found to increase by a factor of 2.6 +/- 0.6, which is approximately the square of the K/pi enhancement.
