英文摘要：

Exploring the statistics and structural characteristics of rough-wall turbulence is of vital importance and essence to the turbulence theory and engineering application. A w e l l-established theory in the rough-wall turbulence study was the w all s im i la r ity hypothesis, to which the latest finding of the inner-outer layer interaction between structures w ith different scales brings a severe challenge. Consequently, the validation of the hypothesis became a hot topic. In views of the current status,the present paper reviews recent major achievements in the rough-wall turbulence at home and abroad,and the possible contents in later research are fu rthe r discussed.
