Of necessity they are sited near the coasts or tidal water .

出于需要，它们都坐落在靠近海岸或潮汐水域附近。

The model is used to predict the tidal water level of Dahengqin station.

并利用该模型对珠江口磨刀门水道的大横琴站的潮位进行预报。

Spring and fall, tidal water level is low, are a good crab catching season.

春天和秋天，潮水的水位很低，都是捉螃蟹的好季节。

The mechanism of the spring-neap tidal water table fluctuations is examined.

分析大小潮水位波动产生的机理；

If the phase change, while the amplitude is almost constant, tidal water level response to meet the transition state.

若相位变化，而振幅几乎不变，井水位潮汐响应满足过渡状态。
