Abstract：
By means of the imaginary-time Green function method in finite-temperature field theory,one ρ-meson exchange potential at finite temperature is obtained.It is found that ρ-meson become lighter in terms of temperature increasing.The result is in good agreement with that obtained from scalling property of QCD.It is also found that temperature dependence of ρ-meson coupling constants is similar to that of,σ-meson coupling constants.
