We have studied the influences of isospin symmetry breaking of nucleon-nucleon interaction on the various properties of asymmetrical nuclear matter and β-stable matter. For asymmetrical nuclear matter, it is found that at large values of both density and asymmetry parameter, the effects of this symmetry breaking are considerable. However, these effects on the total energy and equation of state of β-stable matter are ignorable. For asymmetrical nuclear matter, the validity of the empirical parabolic law in the isospin symmetry breaking case is shown. It is observed that the isospin symmetry breaking of nucleon-nucleon interaction affects the β-equilibrium conditions in β-stable matter.
