Abstract：
The effective potential of the W-S model is calculated both at finite temperature and density from the entire Lagrangian according to the grand canonical ensemble temperature field theory. The two elementary thermal effects in the weak and electromagnetic system are studied. The result indicates that the thermal effects not only counteract the Higgs mechanism effect and help restore the symmetry, but also make the gauge particles keep nonvanishing mass due to the plasmon effects.
