Abstract：
It is discussed the equivalent properties between QMC and QHD models,and then, the in-medium QMC model parameters are determined self-consistently. The results demonstrate that the bag constant and the nucleon radius are greatly influenced by nuclear medium, however, the parameter for the zero-point inchon keeps the same value as in vacuum. The critical curve shows that the QMC model parameters determined in our scheme are valid in low density region (ρ≤1.75ρ0,) todiscuss the finite nuclei and nuclear matter properly.
