英文摘要	Isoscaling behaviour of the statistical emission fragments from the equilibrated sources with Z = 30 and N = 30, 33, 36 and 39 is investigated in the framework of the isospin-dependent lattice gas model. The dependences of isoscaling parameters alpha on source isospin asymmetry, temperature and freeze-out density are studied, and the 'symmetry energy' is deduced from isoscaling parameters. The results show that symmetry energy C(sym) is insensitive to the change of temperature but follows the power-law dependence on the freeze-out density rho. The effect of strength of asymmetry of nucleon nucleon interaction potential on the density dependence of the symmetry energy is discussed.
