| 摘 要： | 利用2004年虎门口ADP的反向散射声强数据，和同步采样经实验室过滤得出悬沙浓度的数据，建立了半经验公式，得到虎门高分辨率的悬沙浓度剖面的时间序列；计算的悬沙浓度与水样法测量的平均相对误差是7．4％，与目前通用的悬沙浓度测量仪器的误差相当，为提高ADP仪器使用效率，更好地研究沉积动力提供一种新的方法。

| Abstract: | The back echo intensity of the waters obtained by using ADP at Humen estuary, the Pearl River in 2004, and synchronous suspended sediment data by experimentation measurement were used to set up a experimental formula, and a time-series profile of high resolution suspended sediment at Humen estuary was calculated by using the formula. The average relative error between the calculated and measured suspended sediment contents is 7.4%, it is inferred that ADP can be used to the measurement of suspended sediments. |
