If the frequencies of the spirals are identical, then depending on the relative rotation direction of the two spirals and their initial separation distance, the two spirals may show complete synchronization, parallel drift, or circular drift.
如果两个螺旋波的频率相同，那么随着两个螺旋波的相对旋转方向以及它们初始距离的变化，它们会表现出完全同步，平行漂移或绕圆圈漂移等现象。
