计算了在电场作用下电荷密度\char 22 {}波凝聚体中由于量子力学隧穿而产生孤子-反孤子对的几率。这一过程引起了一个额外的电导率在电场中强烈的非线性，这可能是部分解释观察到的Nb${\mathrm{Se}}_{3}$的异常导电性。
The creation probability of soliton-antisoliton pairs due to quantum-mechanical tunneling in the presence of an electric field in charge-density\char22{}wave condensates is calculated. This process gives rise to an additional electric conductivity strongly nonlinear in the electric field, which may account in part for the anomalous conductivity observed in Nb${\mathrm{Se}}_{3}$.
