Abstract：
Within Brueckner-Hartree-Fock framework,the equation of state of nuclear matter has been investigated by adopting the charge dependent Argonne V₁₈ two-body realistic force and the microscopic three-body forces based on a meson-exchange model. The contributions to the equation of state from the three-body forces due to different microscopic elementary processes have been calculated and discussed carefully. It is shown by comparing with the results from the relativistic Dirac-BHF approach that the main relativistic correction to nuclear equation of state can be-reproduced fairly well by the present Brueckner-Hartree-Fock calculations including only the three-body force originated from the scalar σ meson exchange coupling to the virtual excitation of a nucleon-antinucleon pair. However,the effects of the three body forces due to other processes can not be cancelled completely with each other,and even around the saturation density of nuclear matter,their net contribution is not neglegible.
