摘　　要：We studied the m=0 limit of different components of Wigner functions for massive fermions. Comparingwith the chiral kinetic theory, we separated the vanishing and non-vanishing parts of vector and axial-vector components,up to the first order of . Then, we discussed the possible physical meaning of the vanishing and non-vanishingparts and their different behaviors at thermal equilibrium.
