【Abstract】 Applying the techniques of the thermal field dynamics (TFD),we investigate the quantum phenomenon of photo radiation and squeezing effect in parametric resonant cavity at finite temperature. The new kind of photons created by the parametric resonance indicates that the exiting of thermal photons can largely enhance the pure vacuum effect and therefore may be crucial for the possible experiments,but the squeezing effect of the intervening cavity field,which is determined by the motion of cavity mirror,is independent on the temperature.更多还原
