Theoretical models for describing intermediate energy NN reactions in the quark degree of freedom are briefly discussed. The NN reactions are classified into three types: annihilation and productions, charge exchange, and elastic scattering, for each of which the possible lowest order diagrams are presented. We also performed calculations to determined if it is proper to include the qq annihilation and creation diagram while to ignore the multiple scattering amplitude in the elastic scattering.
