1. The change of water level is influenced not only by astronomic tide but also bymeteorological factors in the shelf zone.
在陆架海，水位变化既受天文潮影响，也受气象条件影响。
2. The verification results show that the prediction equation is well established for its high accuracy, calculating speed and convenience, and it is suitable and practical for the calculation of astronomic tide at Wusong Hydrological Station.
验证结果表明，预报方程具有精度高、速度快、简便实用等优点，适合于上海市吴淞站天文潮的推算。
3. Wusong Hydrological Station; harmonic analysis of tide; harmonic constant; tide prediction; astronomic tide
因此，准确预报黄浦江入长江口的吴淞站的风暴潮位至关重要
4. In this paper, an astronomic tide prediction model is first established by using a3-D ocean hydrodynamic model—COHERENS for the Bohai Sea region. By usingthe provided harmonic analysis tool and some collected measurements of tideconstituent parameters of several tide stations, the tide parameters of the four tideconstituents are obtained through try-and-error method.
本文首先采用一种三维海洋水动力综合模型—COHERENS模型，利用其调和分析功能，并结合多个验潮站的分潮常数实测结果，通过调试确定边界处分潮常数，建立了渤海海域天文潮预报模式。
5. For all the strong Typhoon and storm surge, the actural water level in Shanghai area did not exceed the warning level because of astronomic low tide.
这次台风过程未对上海市沿海造成超过警戒水位的原因是当台风位置处于有利于产生极大增水时，上海市沿海恰逢天文小潮汛（出现在低潮时）；
\u0064\u0061\u006E\u0063\u0069\u002E\u0039\u0031\u0031\u0063\u0068\u0061\u002E\u0063\u006F\u006D
6. Starting with the research on astronomic factor which arouses tide phenomenon, this paper introduces a method of nonharmonic analysis based on neural network to predict tide.
运用非调和法，直接从引起潮汐现象的天文因素入手，以2002年香港验潮站实测资料为例，用神经网络对潮汐知识进行了学习仿真，对未知结果进行了预报。
