对流体流动的观察清楚地表明，区分具有合理定义的性质的各类流体运动是可行的。
在我们试图研究区分波浪和湍流的可行性之前，重要的是要注意这两种类型的流体运动并不是唯一的。如果假设所有可实现的流动模式都是同一组方程的解，那么原则上它们都具有相同的自由度或可能的运动模式。适用于给定流场的空间和时间边界条件决定了哪些模式可以被激发。
Observations on fluid flows indicate quite clearly that it may be feasible to distinguish between various classes of fluid motions with reasonably well-defined properties.
Before we try to investigate the feasibility of distinguishing waves from turbulence, it is important to notice that these two types of fluid motion are not the only ones. If all realizable flow patterns are assumed to be solutions to the same set of equations, then in principle they all possess the same degrees of freedom or possible modes of motion. The spatial and temporal boundary conditions appropriate for a given flow field determine which modes can and will be excited.
