It is employed the concept of multi-scale coherent structures to study the mechanism of riblet surfacedrag reduction in turbulent boundary layer.
将湍流多尺度相干结构的概念引入沟槽壁面湍流边界层减阻机理的研究。

The parameterization for the soil heat flux and the surfacedrag coefficient are discussed, and the more perfect method needs to combine further with measure experiments.
对土壤热通量的参数化方法和拖曳系数的取值问题进行了讨论，更完善的方法还有待于与实验测量工作相结合。
