Abstract：
In the nuclear medium, there are the non-nucleonic components. The leak-out panons, which form some colour-singlet parton clusters, are the origion of the non-nucleonic components. Meanwhile, the small x partons become co-used by several nucleons because the pamons' longitudinal size extends over more than one nucleon. The nucleon effective mass can be successfully used as the only free parameter to adjust the sbucture function ratios recently measured by NMC.
