英文摘要	Heavy-ion collisions at relativistic energy are studied by the isospin-dependent quantum molecular dynamics model in the company of the GEMINI model. The present study mainly focuses on the liquid-gas phase transition in nuclear matter. We calculate the shear-viscosity-to-entropy-density ratio eta/s, gamma 2 and the multiplicity of intermediate-mass fragment (MIMF) in finite-size nuclear sources. At excitation energy 8 MeV a minimum of eta/s is found in the coexistence phase of intermediate-mass fragments and light particles. At similar excitation energy a maximum of the MIMF is also observed at the same density condition which is an indication of the liquid-gas phase transition.
