摘　　要：本文研究在g_s零阶近似孤粒子袋模型.考虑了夸克间的单胶子交换相互作用,则构成π云孤粒子袋模型.并导出强子各种静态物理性质的解析表达式,给出与实验值基本相符的计算结果.In this paper, the one-gluon exchange interaction between quarks is taken into account in the hamiltonian of the soliton bag model to the zeroth order in g(?). Can be formed, thus resulting in a soliton bag model with pion cloud. The analytical expressions for the static physical properties of hadrons is derived, and the calculated results agree in the main with the experimental data.
