Abstract：
For investigating physical mechanism of the quark distributions due to the nuclear environment under the non-constant K condition the nuclear medium effect on the distribution functions of the sea and valence quarks R Av(x₂) RAs(x₂) is computed by considering QCD non-perturbation effect in the DIS process and energy loss effect in the nuclear Drell-Yan process. Calculated results show that non-perturbative terms or energy loss effect terms have a tiny influence on the nuclear medium effect on the sea quark distribution in the small x₂ region, while a strong influence on the valence quark's. However in the large x₂ region, the non-perturbative or energy loss effects obviously affect the nuclear medium effect on the sea quark distribution.
