With asymptotic method developed from weak turbulent theory, the kinet
ic equations for QGP are expanded in fluctuation field potential A(mu)
(T). Considering the second-order and third-order currents, we derive
the nonlinear permeability tensor function from Yang-Mills field equat
ion, and find that the third-order current is more important in turbul
ent theory. The nonlinear permeability formulae for longitudinal color
oscillations show that the non-Abelian effects are more important tha
n the Abelian-like effects. To compare with other works, we give the n
umerical result of the damping rate for the modes with zero wave vecto
