| 摘 要： | 在过去的10多年内,对于高$Re$数零压力梯度湍流边界层,存在着关于平均速度的尺度律以及近壁区流动是否是普适的争论.介绍了这些争论的最近的态势. 看来, 对于这些争论还远不能得出结论.

| Abstract: | Over the past decade there are debates on the scaling law of the mean velocity and on whether the flow close to a wall can be regarded as universal for zero-pressure-gradient turbulent boundary layers at high Reynolds numbers.The current statuses in these issues are reviewed in the present paper,and these arguments seem still far from conclusion. |

| Keywords: | high Reynolds number turbulent boundary-layer logarithmic scaling power-law scaling |
