Abstract：
By means of the imaginary-time Green's function method,the temperature dependences of the η-meson and nucleon interaction coupling constant and one one η-meson exchange potential are discussed.We find that when temperature increases to 215MeV,the coupling constant approaches to zero and the one η-meson exchange potential of nucleon-nucleon disappears.
