Abstract：
Considering that the original Q ²-rescaling model has some shortcomings in explaining the experimental data,we propose animproved Q ²-rescaling model in which,in order to compensate for the loss of nuclear momentum,we employ different Q ²-rescaling parameters for momentum distributions of valence quark,sea quark and glouns.By using improved Q ²-rescaling model,We can well explain the experimental data of the EMC effect in the whole x region,the nuclear Drell-Yan Process and J/ψ photoproduction process.
