Abstract：
By means of the real time Green's function method,the yukawa potential is extended to finite temperature and finite density.It is found that the effective mass of sigma meson will decrease as the temperature and/or density increase.The results given by the real time Green's function method and the imaginary time Green's function method are compared.
