本文研究了高场下层状超导体2 H-{\mathrm{NbSe}}_{2}$中"准二维“磁通线晶格在垂直于层的场作用下的动力学行为。与数值模拟的比较意味着软晶格的塑性流动的存在。在无序主导的制度，幂律标度形式的I-V曲线产生的电导率指数以上的逾渗阈值的电导率效应更明显。
Dynamics of a ``quasi-two-dimensional'' flux-line lattice in the layered superconductor 2H-${\mathrm{NbSe}}_{2}$ for field normal to the layers is investigated at high fields. Comparisons with numerical simulations imply the presence of plastic flow for soft lattices. Dimensionality effects are more pronounced in the disorder-dominated regime, where a power-law scaling form for the I-V curve yields the conductivity exponent above the percolation threshold.
