2014通常，在超临界条件下，稳定的细胞结构（如泰勒-库埃特实验中的卷）可以在有限带中具有任意波数，以获得无限模式。如果外部条件变化缓慢，则波长变为局部控制参数的函数。如果一个亚临界区域光滑连接到一个超临界区域，在超临界区域的稳定辊的波长是唯一定义的，指数小的条款。
2014 Usually, in supercritical conditions, steady cellular structures (as rolls in Taylor-Couette experiments) may have any wavenumber in a finite band for an unbounded pattern. If the external conditions change slowly, the wavelength becomes a function of the local control parameter. If a subcritical region is smoothly connected to a supercritical one, the wavelength of steady rolls in the supercritical region is uniquely defined, up to exponentially small terms.
