Abstract
In the non-Ohmic regime the total differential conductivity of obeys a simple scaling relationship when the Ohmic conductivity is used as the scaling parameter, viz., dj(E,)/dE=g()+f( )E. This equation is valid for fields E varying from 2 up to 500 at 50 K (where is the threshold field). We have also verified it over the range of temperatures 50 K>T>15 K. Implications for the theory of charge-density-wave transport are discussed.
