  The self-consistent Thomas-Fermi approximation is an essential method for
studying the non-uniform nuclear matter with relativistic mean-field theory. In
this method, the nucleon distribution in the Wigner-Seitz cell is obtained
self-consistently. We make a detailed comparison between the present results
and previous calculations in the Thomas-Fermi approximation with a
parameterized nucleon distribution that has been adopted in the widely used
Shen equation of state.
