The report showed that 16.1 percent of children affected by the conflict in Darfur, a vast, turbulent region in western Sudan, are acutely malnourished, compared with 12.9 percent last year.

报道表明，由于受到苏丹西部一个广袤且动荡的地区——达尔富尔的冲突影响，严重缺乏营养的孩子，同去年的12.9%相比，今年是16.1%。

The results show that the shock wave structure is unsteady in shock induced hypersonic turbulent separated flows, generating an intermittent region.

结果表明：在激波诱导的高超音速湍流分离流中，激波结构是不稳定的，产生一个间歇区域。

The theoretical model of the coherent structure in the wall region of a turbulent boundary layer was proposed, using the idea of general resonant triad of the theory of hydrodynamic stability.

利用流动稳定性理论中的一般共振三波的概念，提出了湍流边界层近壁区域相干结构的理论模型。

Like in an infinite flow, we find that laminar boundary layer, transition region and turbulent boundary layer also exist along a flat plate in open channel flow boundary layers.

试验研究发现明流光滑平板边界层中，与无限边界绕流平板边界层一样，沿平板有层流边界层，转捩区和紊流边界层三部分。

The results indicate that coating a compliant wall makes the logarithmic region of a turbulent boundary layer shift upwards as unstable hydrodynamic waves are absent.

这说明，在没有水动力学不稳定发生的情况下，柔性壁会使湍流边界层中速度型的对数区上移。
