Abstract：
The isoscalar giant surface resonance and giant dipole resonance in highly excited nuclei are discussed.Excitation energies of the giant modes in ²⁰⁸Pb are calculated in a simplified model,using the concept of energy weighted sum rule (EWSR),and the extended Thomas-Fermi approximation at the finite temperature is employed to describe the finite temperature equilibrium state.It is shown that EWSR and the enrgy of the resonance depend only weakly on temperature in the system.This weak dependence is analysed.
