✦ Synopsis

In this paper', the differences of turbulent coherent structure'betueen tire smooth and rough boundarr layers are analysed. Based on the discussing the transient properties from the smooth wall to the rough wall, the physical model of coherent structure for the rough botmdao" layer are established. The width of slowh'-moring turbulent spot and the bursting tone are obtained, which are in agreement with e.x'perfl~ental results.

Mean products of velocity fluctuations up to fourth order have been measured in a wind tunnel at the trailing edge of a flat plate, one side of which was covered with floor-sanding paper to produce a fully rough surface. This set-up permits easy comparison of structural parameters in smooth-wall and
