Abstract：
Based fully on the finite temperature field theory, we calculate the Feynman diagram to analyse the new infrared divergence caused by the temperature effect in the bremsstrahlung process. It turns out that both of the infrared divergence at the zero and finite temperature can be cancelled by the identical Feynman diagram of virtual processes. We derive the probability of radiating a net energy ω in bremsstrahlung processes and the result in Eikonal approximation is the same as that obtained in the semi-classical approximation.
