We have developed a theoretical model that describes the interaction of
 intense pulsed flows of energy with matter and is based on the account of local phase
 transitions at the destruction of a surface. In the frame of a problem concerning the
 influence of a laser radiation on the surface prior to the beginning of the solid surface
 destruction, we have solved the equation for the energy flow. The general solution of the
 equation for the temperature change of a local area of the irradiated solid surface in time
 is obtained with regard for the coefficient of surface dissipative losses and the volume
 absorption coefficient. It is shown that the temperature dynamics stimulated by the
 intense laser radiation depends substantially on properties of the surface layer of the
 irradiated material.
