英文摘要	The in-medium neutron-proton, proton-proton (neutron-neutron) scattering cross sections (sigma(np), sigma(pp(nn))) are studied based on QHD-II type Lagangian within the framework of the microscopic transport theory. The results demonstrate that, for free nucleon-nucleon scattering cross sections, the isospin dependence is dominantly caused by the rho meson field. The medium correction of nucleon-nucleon scattering cross sections is also isospin dependent, sigma(np), depends on the baryon density weakly and sigma(pp(nn)) depends on the baryon density significantly, which is due to the different effects of the medium correction of nucleon mass and rho meson mass on sigma(np) and sigma(pp(nn)), respectively.
