主　　题：equal-time transport rotation field kinetic theory 

摘      要：We investigate quantum kinetic theory for a massive fermion system under a rotational *** theDirac equation in rotating frame we derive the complete set of kinetic equations for the spin components of the 8-and 7-dimensional Wigner *** the particles are no longer on a mass shell in the general case due to therotation-spin coupling,there are always only two independent components,which can be taken as the number andspin *** help from the off-shell constraint we obtain the closed transport equations for the two independent components in the classical limit and at the quantum *** classical rotation-orbital coupling controls thedynamical evolution of the number density,but the quantum rotation-spin coupling explicitly changes the spin density.
