Abstract：
The relaxation of the isoscalar giant monopole resonance (GMR) in the hot nuclei produced in heavy-ion reactions is discussed based on the Boltzmann-Nordherin-Vlasov equation. The oscillation of the GMR in the spherical hot nuclei is isotropic. The GMR energy calculated is approximately equal to that resulting from the formula E _GMR=80 A ^-1/3. The nucleon collision and the particle escape are the dominant reasons for the relaxation of the GMR in the hot nuclei.
