海湾中的潮汐余流,由于它对海洋工程以及海湾的污染扩散,都有着直接的影响。因此,它已作为潮汐动力学中一个新的研究课题,越来越受到有关学者的重视。人们用不同的方法,探讨了潮汐余流产生的物理机制,取得了一定的成果。北部湾是一个内陆浅海,三面被陆地所环绕,北面及东面是中国大陆和海南岛:西接越 The tidal currents in the bay have a direct impact because of its impact on ocean engineering and on the pollution of the Gulf. Therefore, it has been regarded as a new research topic in tidal dynamics and more and more concerned by scholars. People use different methods to explore the physical mechanism of tidal residual flow, and achieved some results. North Bay is an inland shallow sea surrounded by land on three sides, north and east of China and Hainan Island: West to Vietnam
