Statistical analysis is made for current speed frequency distribution besides harmonic analysis for these current data. The results show that the near-bottom current speeds mainly concentrate on the range of 6- 15 cm/s at frequency of 47 percent, the cumulative frequency at 25 cm/s reaches 86 percent, and maximum speed measured is 48 cm/s.展开更多
