首次在向列液晶电流体对流矩形图案中观察到宏观圆形和螺旋相波传播。一般来说，相位波传播的中心既不是矩形结构的缺陷，也不是外部不均匀性。局部测量的透射光的功率谱表现出两个峰值，一个是相应的相位波模式，另一个是非夹带模式。相波模式的频率低于其他模式的频率。
Macroscopic circular and spiral phase wave propagation was observed for the first time in the rectangular pattern of electrohydrodynamic convection of nematic liquid crystal. The centers of the phase wave propagation were, in general, neither defects of the rectangular structure nor external heterogeneities. The power spectrum of the transmitted light locally measured exhibited two peaks, one a corresponding phase wave mode and the other an unentrained mode. The frequency of the phase wave mode was lower than that of the other mode.
