    In this paper that the dimensionless streak-spacing λv of the low-speed in the regions very near the wall are about the same was demenstrated by hydrogen bubble generation technique, and it was found that the *v, increases as the distance from the wall increses. The characteristics of the coherent structure of wall shear turbulence and its forming process have been analysed with the figure of the coherent structure visualization. The calculation formula of burst period has been obtained. In view of the determinant effect of the coherent structure on the production of the turbulence fluctuation,the relation between the coherent structure and the wall-pressure were discussed in the second part of this paper. Through calculating, that the wall-pressure fluctuation arises from the coherent vortex of low-frequency and in large scale has been demonstrated.In this paper the sampling collection and sampling average methods which reflect the coherent structure feature were introduced in order that the wall-pressure fluctuations were reasonably calculated.

    本文通过氢气泡产生技术,证明了边壁附近的慢速流带无因次分布间隔(λ_v)有大致相同的数值,而且发现λ_v随距边壁的距离增加而增大;由相干结构显示图,分析了边壁切变紊流相干结构的特性及其形成过程,而且得出了猝发周期的计算式。由于相干结构对紊流脉动的产生及由此产生的各种物理效应起决定性作用,因而本文第二部分讨论了相干结构与脉动壁压的关系,通过对实测的脉动壁压计算,证明了脉动壁压主要是低频大尺度相干涡旋所引起的,为了更合理地计算脉动壁压,文中介绍了反映相干结构特性的条件采样和条件平均计算法。
