用含时平均场理论研究了杂质钉扎电荷密度波的非线性电场响应。发现在阈值电场ET以上，电荷密度波以速度v（E-ET）3 2移动。一些一般性的讨论的行为作为一个功能的尺寸。
A time-dependent mean-field theory of the nonlinear electric field response of a charge-density wave pinned by impurities is implemented. It is found that above a threshold electric field E T, the charge-density wave moves with velocity v∝(E− E T) 3 2. Some general discussion of the behavior as a function of dimension is included.
