Abstract：
By means of the real time Green's functions, the elementary excitation spectra of Mohapatra-Senjanovic model at finite temperature are given. It is shown that the results given by first order normal pair and abnormal pair cut off approximation of the equations of motion is in good agreement with the results given by DJWB effective potential method under one loop approximation. The correlations between mass and temperature, condensational density and temperature of four elementary excitation spectra are also presented.
