The quark mean field model, which describes the baryon using the constituent quark model, is applied to study the properties of finite nuclei and hypernuclei.

Based on the quark model, the Q 2 evolution of the nucleon spin structure functions in the small Q 2 region is calculated.

The energies of the low-lying isoscalar and isovector ud■ configurations with spin-parity J~P=0~+, 1~+,and 2~+ are calculated in the chiral SU(3) quark model and the extended chiral SU(3) quark model by using the variational method.

We study the decay widths of the narrow resonances D*sj(2317) and Dsj(2460) in the chiral quark model, together with the well-known D* and D*s mesons.

17〕,an approximate mass of 3000 MeV/C2,a constitutional formulac,a large of problems are analyzed and calculated with the new quark model and a series of re-sults are obtained,such a series of results are highly consistent with the corresponding experimental results of the particle J/ψ.

Based on our new quark model the constitutional form of particle X(1835) is determined by six-quarks state,its main decay mode is Xγπ~+π~-η′ and mass is m=1 835 Mev/c~2,and width is Γ=65±16 Mev/c~2,and life time is τ(x)=1.
