统计分析的速度波动的近壁区域的有壁流动。通过要求波动的小尺度部分满足局部轴对称性的约束，人们发现，小尺度必须在近壁区域被完全抑制。这一主要结论得到了直接数值模拟的所有可用数据的支持。
Statistical analysis of the velocity fluctuations is performed for the near-wall region of wall-bounded flows. By demanding that the small-scale part of the fluctuations satisfies constraints imposed by local ax symmetry it was found that the small scales must be entirely suppressed in the near-wall region. This major conclusion is well supported by all available data from direct numerical simulations.
