英文摘要	Within the framework of Hartree-Fock theory by using the extended Skyrme effective interaction, the density dependence of symmetry energy is derived analytically with parabolic approximation at zero-temperature. It is shown that the parabolic approximation is applicable within a rather large density region and almost for all relative neutron excess. The symmetry energy depends on density terms of rho(2/3), rho, rho(y+1), rho(5/3) and rho(y+5/3). At finite temperatures, the parabolic approximation between symmetry energy and relative neutron excess is still appropriate. In addition, the temperature dependence of symmetry energy is predicted. It is found that the symmetry energy decrease with increment of temperature and the parabolic law between symmetry energy and temperature is satisfied at lower temperatures.
