在研究我国浅海的水文因子周日(昼夜)变化时,不难发现,在许多地区,这种变化具有潮振动性质。引起这种周期性变化的原因可能有二:(1)直接由潮汐运动,尤其是潮流所引起;(2)由内潮振动所引起。关于内潮现象,作者在“海洋中的内波现象”一文中,已作了较详细的介绍。这里只补充一点,即:由于内潮理论上的困难,在研究方法上也出现了一些不同的意见。认为,由潮汐运动引起的,并在时间上与潮汐一样变化着的任何过程,均可用相同的方法去进行研究。等更直接用潮汐学上的调和分析法,研究了水温的潮振动。认 When studying the changes of the hydrological factors in the shallow sea of ​​our country on the day of the week (day and night), it is not difficult to find that in many areas the changes have the characteristics of tidal vibration. There are two possible reasons for this cyclical change: (1) direct tidal movements, especially tidal currents, and (2) vibrations caused by internal waves. As for the phenomenon of internal tide, the author has made a more detailed introduction in “The Internal Wave Phenomenon in the Ocean”. Here only to add that: due to the theoretical difficulties in the tide, in the research methods also appeared in a number of different opinions. Think of any process that is caused by tidal movements and that varies in time with tides, and can be studied in the same way. And more directly with the harmonic analysis of tidal theory, the water temperature tidal vibration. recognize
