Abstract: Using a hadron and string cascade model,LUCIAE,the Φ meson production in relativistic nucleus-nucleus collisions was systematically investigated from AGS energy,to SPS,to RHIC,up to LHC energy. After considering the energy dependence of the model parameter in string fragmentation function and fitting it to the experimental data of charged multiplicity,the results of Φ meson yield were comparable with experimental data. The obtained string fragmentation variable showed a saturation in dependence with energy,that might be a qualitative representation of the energy dependence of nuclear transparency.
