摘要：

The shear viscosity (η) and entropy density (s) are studied for the central Au+Au collisions with the help of a microscopic transport model,namely the isospin-dependent quantum molecular dynamic model (IQMD).Employ the formula given in Ref.[1],η is calculated as a time dependent variable for different incident energies from 40 MeV/u to 120 MeV/u and the energy dependence of η/s of nuclear matter in the most compressed stage in collision process is displayed.
