英文摘要	The contributions of delta-isovector-scalar and rho-isovector-vector meson-exchanges to nucleon-nucleon elastic cross-sections (ECS) are studied based on QHD-type effective Lagrangian within the framework of the RBUU transport theory. The detailed expressions of ECS for symmetric nuclear system have also obtained. The medium correction of rho-meson mass and a proper symmetry energy coefficient are selected in order to fix a set of suitable coupling constants for delta and rho exchanges with the constraint of free ECS as a function of energy. The respective delta and rho contributions to free ECS as a function of energy are also shown and it is found they both affect the neutron-proton and neutron-neutron (proton-proton) ECS on the contrary way.
