在考虑尘埃等离子体介质中低频波的适当非线性和色散性质的驱动的Korteweg-de Vries-Burgers方程的框架下，研究了尘埃声波与外部周期源的同步。对于时空变化的源项，系统表现出简谐(1：1)和超谐(1：2)的同步态。在强迫振幅和强迫频率的参数空间中，用Arnold舌图的形式描述了这些态的存在域，并讨论了它们与以往一些实验结果的相似性。
The synchronization of dust acoustic waves to an external periodic source is studied in the framework of a driven Korteweg–de Vries–Burgers equation that takes into account the appropriate nonlinear and dispersive nature of low-frequency waves in a dusty plasma medium. For a spatiotemporally varying source term, the system is shown to demonstrate harmonic (1:1) and superharmonic (1:2) synchronized states. The existence domains of these states are delineated in the form of Arnold tongue diagrams in the parametric space of the forcing amplitude and forcing frequency and their resemblance to some past experimental results is discussed.
