摘要
通过建立夸克一介子耦合（QMC）模型与量子强子动力学（QHD）模型的等价性条件，自洽地定出了介质相关的QMC模型参数，数值计算表明，QMC模型袋参数及核子袋半径受核物质影响较大，而零点运动参数则不受影响．
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.
