采用广义 Cahn-Hilliard 模型研究了时间强迫对 Langmuir-Blodgett 传递中模式形成的影响。发生的锁频效应允许控制图案形成过程。在一维（即条纹）图案的情况下，人们会发现各种同步现象，例如沉积条纹的距离和强迫频率之间的夹带。在二维中，时间强迫导致了错综复杂的图案的形成，例如垂直条纹、倾斜条纹和晶格结构。值得注意的是，可以在垂直于力方向的空间方向上影响系统，从而导致两个空间维度上的同步。
The influence of a temporal forcing on the pattern formation in Langmuir-Blodgett transfer is studied employing a generalized Cahn-Hilliard model. The occurring frequency-locking effects allow for controlling the pattern formation process. In the case of one-dimensional (i.e., stripe) patterns one finds various synchronization phenomena such as entrainment between the distance of deposited stripes and the forcing frequency. In two dimensions, the temporal forcing gives rise to the formation of intricate complex patterns such as vertical stripes, oblique stripes, and lattice structures. Remarkably, it is possible to influence the system in the spatial direction perpendicular to the forcing direction leading to synchronization in two spatial dimensions.
