摘要
东中国海作为太平洋的边缘海，它的潮差大，潮汐类型复杂，过去研究不多。Борис、Каган、安希洙等人曾对黄渤海潮汐做过数值研究，小仓伸吉曾用等高线法作等潮图研究过东中国海的潮汐。本文首次对整个东中国海潮汐做数值计算，旨在探索协振潮波的传播和潮汐分布的总规律。计算结果与实际资料基本符合。
For the East China Sea the hydrodynamical equation system of the co-oscillating tides is numerically solved by giving the values of tidal harmonic constants at the boundaries. Based on the computed results the co-tidal charts of four main constitueuts are drawn. with the help of the charts the propagation behaviours of tidal waves in the region analyzed, the formation of amphidromic systems and the distribution of tidal characteristic quantities are deiscribed. The author is of the opinion that there exists a semi-durnal degenerate amphidromic system near Jilong, Taiwan.The comparision between the computations and the observations exhibits excellent agreement, thus suggesting that our results can serve general purposes.
