%X The threshold energies of radial flow in reactions of 40Ca+40Ca and 48Ca+48Ca in central collisions are investigated within an isospin dependent quantum molecular dynamics model by using three different forms of symmetry energy. It is found that the neutron-rich system has smaller threshold energy of radial flow and this quantity depends on the form of symmetry potential. It is indicated that the threshold energy of radial flow canprovide a new method to determine the symmetry energy of asymmetric nuclear matter.
