摘要
世界各国对海洋潮汐运动的研究由来已久,现在,对世界各主要港口的潮汐已能够进行较准确的推算和预报。然而,随着观测手段的进步和资料的不断积累,人们愈加感到大洋中(包括赤道区在内)的潮汐运动,实际上比人们所想象的要复杂得多,不仅其潮位(流)的大小因地而异,而且其高潮间隙、潮令也千差万别。
In this paper,the solution of one-dimentional equations of forced damping oscillation is obtained,and the response of ocean to the tide-producing force is discussed.The response is simple in boundless ocean with simple forced progressive wave,but much complicated in closed ocean with multiple progressive waves and stationary waves.In a semi-closed sea,the movement of tidal waves consisting of co-oscillating tide and independent tide is very complicated,with the former tide being simpler than the latter.The analysis of the response function of tidal waves shows that there is no essential difference between the equilibrium and dynamic tides,the former is only a particular case of the latter.In addition,the contribution of frictional force to the forced oscillation is also discussed.
