Abstract ： The effective mass of ρ-meson in medium has been calculated for the Welecka, Bonn potential, Zimanyi-Moszkowski, quark-meson coupling and vector-tensor coupling models, respectively. The vacuum fluctuation effects are taken into account. It is shown that the formula of nucleon effective mass suggested by Brown-Rho scaling can get a best fit with experiments provided the adjusted parameter y equals to 0.10 and 0.19 for strong and weak tensor coupling, respectively.
