The dynamic properties of a pure 1D incommensurate CDW system in an electric field are reexamined for the non-relativistic (Lee-Rice-Anderson) model, as well as the one of a relativistic (R) form. The effective Lagrangians of the system and the equations of current acceleration of the two models coincide with each other as expected at least at zero temperature. In the R model the current acceleration equation is a consequence of the chiral anomaly inherent to the 1+1 Dirac (electron) field. IN the non-R model, on the other hand, the same equation is compatible with the conservation law of chiral charge. We also discuss how to deal with the chiral anomaly of the R model in the phase Hamiltonian method.
