Abstract：
In this paper,the nucleon-nucleon elastic cross section σnn(E,ρ) in medium has been calculated and discussed at nonrelativistic energy region by using Skyrme interaction. It is found that under Pauli correction σnn in medium is larger than free nucleon-nucleon cross section for lower densities,and σnn in medium above spacial energy is larger than free nucleon-nucleon cross section for higher densities.
