摘　　要：简述了已知的粒子质量公式,由动力学的对称性自发破缺机制导出粒子的动力学模型和振动-转动模型,其简化形式是谐振子模型.由此得出某些与实验符合的定量结论和重味强子的质量关系,同时提出了新的轻子-介子(v,e;μ,π,K)与重子(p,n;Λ,Σ,Ξ)同位旋I相应的对称性.The known mass formulas of particles are introduced briefly. The dynamical model and the oscillation-rotation model of particle are derived from the dynamical mechanism of spontaneously break symmetry, and its simplified form is a harmonic oscillator model. Further, with the experiments,the results can be obtained that some quantitative results agree with experimental data and the mass relations of hadrous with heavy flavor are obtained. Finally, a new symmetry between lepton-meson （ v, e ;μ ,π, k） and baryon （p, n ; △ ,∑, [1]） with corresponding isospin I is proposed in this paper.
