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