Abstract：
The φ meson production in relativistic nucleus-nucleus collisions is investigated systematically using a hadron-string cascade model LUCIAE. Within the framework of the model and relying on the collective effects in the gluon emission of string and the reduction of the s-quark suppression, the NA49 data of φ meson enhancement in the 158 A GeV/c Pb+Pb collision relative to that in p+p collision at the same energy is reproduced in certain extent.
