| 摘 要： | The effective potential of $\lambda$$\varphi$41+3 model with both signs of parameter m2 is evaluated at T=0 by means of a simple but effective method for regularization and renormalization. Then at T≠0, the effective potential is evaluated in imaginary time Green function approach, using the Plana formula. A critical temperature for restoration of symmetry breaking in the standard model of particle physics is estimated to be Tc≌510 GeV.
