In a thin layer of a nematic liquid crystal confined within a small aspect ratio cell, window-like coherent states and their subharmonic bifurcations have been found to occur in a successive transition process of the Williams domain. By an increase of the voltage applied across the thin layer of the liquid crystal, the Williams domain becomes unstable and two-types of coherent pattern oscillations OS1 and OS2 appear successively. In the region of OS1, the pattern oscillation repeats the window-like c oherent states and their sub-harmonic bifurcations. The oscillation OS2 shows another pattern behavior different from the OS1.

在限制在小纵横比细胞内的列液晶的薄层中，发现像窗一样的相干状态及其亚谐波分叉发生在威廉姆斯域的连续过渡过程中。通过在液晶薄层上施加的电压的增加，威廉姆斯结构域变得不稳定，两种相干模式振荡OS1和OS2的两种型出现。在OS1的区域中，模式振荡重复了窗户状的循环状态及其亚谐波分叉。振荡OS2显示了另一种与OS1不同的模式行为。
