Abstract：
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. The meson mean fields couple directly with the quarks and change the properties of baryons in nuclear medium. The quark mean field model provides satisfactory results on the properties of spherical nuclei and hypernuclei. it also predicts an increasing size of the nucleon as well as a reduction of the effective mass in the nuclear environment.
