| 摘要: |
| 关于我国近海(124°E以西)潮汐和潮流的基本特征,在1958-1960年全国海洋普查报告中曾进行过分析和研究。近20年来,除积累了更多的资料以外,在分析、计算方法以及潮汐理论方面,也都有了很大的进展。本文拟采用一些新的计算方法,尽可能地搜集了研究海区的所有资料,使用电子计算机,对潮汐潮流各要素进行了计算,并根据计算结果分析研究这些要素的分布特征。 |

| Abstract: |
| In this article, using tidal differential equation, the gradients of the tidal levels were calculated with the data of tidal current in the sea；and then the tides in the sea have also been predicted by means of the tidal data at the coastal station. Simultaneously, the quasi-maximum velocity of tidal current, the energy imported into the East China sea by the sum of the M2 and S2 of the main semidiurnal constituent and its dissipation have been caleulated. In addition, the tide and tidal current properties,the propagation of the tide waves, quasi-maximum velocity of tidal current and the transport of the tidal energy have also been discussed. |
