通过把QMC模型参数展到σ场的一阶项来引入模型参数的核介质效应，并利用核子袋在介质中的平衡条件自洽地确定展开系数．计算结果表明袋参数及核子半径受介质影响较大，而零点运动参数则保持不变．在此基础上，分析了介质相关的模型参数对核物质状态方程及夸克凝聚的影响． The QMC model parameters are introduced into the first order of the σ field to introduce the nuclear medium effect of the model parameters, and the expansion coefficient is determined by using the equilibrium condition of the nuclear pocket in the medium. The calculation results show that the bag parameters and the nucleus radius are greatly influenced by the medium, while the zero-point movement parameters remain unchanged. On this basis, the influence of medium-related model parameters on the equation of state of matter and quark condensation is analyzed.
