摘要
不同研究者所给出的南沙及其西南海域的同潮图历来有很大差别。为了给出更准确的同潮图，本文采用沿岸和岛屿200多个验潮站的调和常数给出了M2，S2，K1和O1四个主要分潮新的同潮图，同时还探讨了这些分潮之间的关系。研究表明，M2和S2在泰国湾的期波系统很相似，但在卡里马塔海峡和爪哇海差别相当大。M2潮波基本上属于驻波性质，而S2潮波则具有向西传播特征。在某些区域，如望加锡海峡的部分区域，S2的振幅可以超过M2。泰国湾中K1和O1的潮波系统也相类似。在卡里马塔海峡，这两个潮波都向南传播，但在爪哇海，O1潮波继续向东传播而K1潮波则倒过来向西传播。
The historical cotidal charts for the Nansha sea area and its adjacentsouthwest waters drawn by different investigators demonstrate great differences. To provide more accurate charts the harmonic constants at more than 200 tidal stations onislands and coasts are employed to construct new cotidal charts for the principalconstituents M2 S2, K1 and O1 in this area. The sum of these constituents and the relations between them are also illustrated. The tidal regimes of M2 and S2 in the Gulfof Thailand are similar, but in the Karimata Strait and Java Sea they revealsignificant difference. The M2 wave is basically of standing nature, while the S2 wavepossesses a westward propagating property. In some area, such as a part of theMakasar Strait the amplitude of S2 exceeds that of M2 The tidal regimes of K1 andO1 are also similar in the Gulf of Thailand. Both diurnal waves propagate southwardin the Karimata Strait. But in the Java Sea the O1 wave continues to propagateeastward and the K1 wave reversely propagates westward.
