摘要：
The equation of state of nuclear matter is studied in the 1-loop approximation of chiral linear sigma-omega model. By introducing the density-dependent coupling constants, the problem of tachyon pole in the chiral sigma-omega model is resolved. The 1-loop contributions of sigma and pi mesons to the nucleon's binding energy are included, while the empirical properties of nuclear matter such as saturation density, binding energy, and incompressibility are well reproduced.
