利用在边界层转捩中逐渐建立起来的主要动力学过程 ,对湍流级串概念做了进一步的分析 .对边界层转捩的测量结果进行定量分析 ,从所得能谱中可以清楚看到湍流级串与转捩的动力学过程的对应关系 ,进而丰富了对湍流级串的理解 The concept of turbulence cascade is further analyzed by using the main kinetic process gradually established in the transition of the boundary layer.Quantitative analysis of the results of the transition of the boundary layer shows that the turbulence level The correspondence between the kinetic processes of strings and transitions enriches the understanding of the turbulence cascade
