中文摘要：

潮的主要特征被忍受的一艘轮船调查在从 2003 年 4 月 4 日位于 Beibu 海湾的一个固定车站的声学的 Doppler 当前的剖析程序。数据分析显示日报潮汐的水流在观察地点统治本地当前的变化。除了 barotropic M_2 成分，四主要的潮包括前后的 barotropic 和 baroclinic 潮汐的水流。潮汐的椭圆参数与深度改变的 baroclinic，出现复杂化特征，而非单调的特征正在被考虑。为 baroclinic 潮汐的成分，垂直模式对对方不同。同样，潮汐的成分的半专业轴与深度变化。在更低的层，一条非线性的回归途径被用来计算并且获得 SEMA 侧面日报潮汐的成分。结果证明在薄底部边界层，所有与深度急速地参数变化，完全与上面的垂直侧面区分开来。

英文摘要：

The principal characteristics of the tides are investigated by a shipborne acoustic Doppler current Profiler at a fixed station located in the Beibu Gulf from 4 to 14 April 2003. Data analysis indicates that the diurnal tidal currents dominate local current variations at the observing site. Except the barotropic ME constituent, four principal tides comprise both back-and-forth barotropic and baroclinic tidal currents. The baroclinic tidal ellipse parameters vary with depth, showing complicate features, rather than monotonous features being figured. For baroclinic tidal constituents, vertical modes are different to each other. Similarly, the semi-major axes of the tidal constituents vary with depth. In the lower layer, a nonlinear regression approach is used to calculate and obtain the SEMA profiles of diurnal tidal constituents. Results show that in the thin bottom boundary layer, all of the parameters vary drastically with depth, totally distinguished from the vertical profiles above.
