中文摘要：

对夸克-介子耦合模型的研究进展及现状进行了简述。在此基础上,利用非拓扑孤子袋模型的思想和改进的夸克质量密度相关（IQMDD）模型,考虑夸克之间的排斥作用而加入ω介子,称为IQMDD-I模型,得到了基态波函数和介子场满足的方程。利用平均场近似方法,通过得到的基态夸克波函数计算了核子的均方根半径和磁矩等可观测量,其结果与实验值吻合得较好。

英文摘要：

The improvement of the quark-meson coupling model is introduced.To describe the effect of repulsion in quarks,based on the improved quark mass density-dependent model（IQMDD）,we develop an IQMDD-I model in which ω meson is included.Then we obtain a set of equations about quarks and σ,ω mesons in terms of related means field approximation.The rms charge radius,the magmetic moment,and the ratio between the axial-vector and the vector β-decay coupling constants of the nucleon are calculated.It is shown that the results of the model are in agreement with experiment values.
