摘　　要：对孤粒子袋模型数值解时,考虑了夸克质量和质心修正,获得强子静态物理性质(如质量、磁矩、均方根电荷半径和轴矢量与矢量耦合常数之比等),理论值与实验值基本相符。同时推算出上、下夸克间的质量差。In this paper, in finding the numerical solution of the soliton bag model, the mass of a quark and the masscenter corrections are taken into account. The resulting static physical properties of hadrons (such as the mass, the magnetic moment, the r.m.s, charge radius and the ratio of the axial vector to the vector coupling constant, etc. )are obtained. It is shown that the theoretical values are in good agreement with the experimental ones. The mass difference between d quark and u quark is also dciivcd in this paper.
