Abstract：
In this paper, in consideration of the recombination among sea quarks and gluons leaking out of the bound nucleon, and the evolution of partons confined in the nucleon due to the change of confinement size, we give a general description of nuclear gluon distribution and calculate the gluon radio of nuclei Sn to C, which is in agreement with NMC experimental data.
