Abstract：
The contributions from the three-gluon condensates to the finite temperature QCD sum rule for the ρ-meson are calculated, and then the dependence of the properties of the ρ-meson upon temperature is investigated in a string model of condensates. Our results show that the parameters characterizing the properties of the ρ-meson change noticeably When the temperature closes to the critical temperature of the condensates, and if the critical temperatures of condensates are the same.
