  "abstract": "Based on the recently updated Isospin-dependent Boltzmann-Uehling-Uhlenbeck (IBUUy) transport model, we studied the effects of the symmetry energy on the neutron to proton n/p ratio and the $\\pi^{-}/\\pi^{+}$ ratio in central $^{132}\\rm {Sn}+^{124}\\rm {Sn}$ reactions at 300 MeV/nucleon. It is found that the pions and nucleons yield ratios in central $^{132}\\rm {Sn}+^{124}\\rm {Sn}$ reactions at 300 MeV/nucleon mainly probe the symmetry energy in the density region 1-1.5 times saturation density. However, the $\\pi^{-}/\\pi^{+}$ ratio may probe the density-dependent symmetry energy above 1.5 times saturation density by making some kinematic restrictions such as the azimuthal angle and kinetic energy cuts of emitting pions.",
