Abstract：
The double Q²-rescaling model is used to calculate the variation of K-factor with x₂ when the nucleus A-nucleus A collision (for example, C, Ca, Fe, Sn) occurs at different values of x₁, where x₁ and x₂ are momentum fraction variables. In this calculation, the contributions of annihilations and Compton scattering have been taken into account in the Drell-Yan process. The numerical results show that the plots of K-factor versus x₂ are somewhat dependent on the values of x₁ and that K-factor could not be regarded as a constant because it changes with A-nucleus to some extent. These results can be used to test the validity of the nucleus model and the adaptability of QCD theory.
