Abstract：
In this paper,the Mean-Field Approximation is applied to the soliton bag model to calculate static physical proporties of hadrons of hadrons numerically.After taking account of the quark masses and the corrections of the center of mass the g_A/g_V value is improved evidently and the hadron mass spectrum,the r.m.s charge radius and the magnetic moments of the hadrons are basically in agreement with their experimental values.A preliminary derivation of the mass differencs between the d and u guarks is presented.
