中文摘要：

根据一个美国的最近的版本，海军概括了数字环境模型(GDEM-V3.0 ) 和世界海洋地图集(WOA13 ) ，水力的理论被重游并且适用于吕宋岛海峡，在在那里的深海的溢出提供新鲜的看。结果揭示那：(1 ) 吕宋岛海峡的二个方面之间的坚持的密度差别从西方的太平洋支撑全年深海的溢出到华南海(SCS ) ；(2 ) 深海的溢出的季节的可变性不仅被变化，而且由变化在它的在上游的层厚度处于吕宋岛海峡的二个方面之间的密度差别影响；(3 ) 在吕宋岛海峡的深海的溢出显示出弱一年两次的可变性；(4 ) 在 SCS 深盆的季节的吝啬的发行量模式同时地不在吕宋岛海峡对深海的溢出的 seasonality 作出回应。而且，深海的溢出在 12 月到达它的季节的最大值(基于 GDEM-V3.0 ) 或在秋天(10 月 12 月，基于 WOA13 ) ，在吕宋岛海峡的和平的方面上由一年的最低温度伴随了。深海的溢出的季节的可变性与最长存在一致(3.5 一) 沿着吕宋岛海峡的主要深海的经过的连续观察。

英文摘要：

On the basis of the latest version of a U.S. Navy generalized digital environment model （GDEM-V3.0） and World Ocean Atlas （WOA13）, the hydraulic theory is revisited and applied to the Luzon Strait, providing a fresh look at the deepwater overflow there. The result reveals that： （1） the persistent density difference between two sides of the Luzon Strait sustains an all year round deepwater overflow from the western Pacific to the South China Sea （SCS）; （2） the seasonal variability of the deepwater overflow is influenced not only by changes in the density difference between two sides of the Luzon Strait, but also by changes in its upstream layer thickness; （3） the deepwater overflow in the Luzon Strait shows a weak semiannual variability; （4） the seasonal mean circulation pattern in the SCS deep basin does not synchronously respond to the seasonality of the deepwater overflow in the Luzon Strait. Moreover, the deepwater overflow reaches its seasonal maximum in December （based on GDEM-V3.0） or in fall （October-December, based on the WOA13）, accompanied by the lowest temperature of the year on the Pacific side of the Luzon Strait. The seasonal variability of the deepwater overflow is consistent with the existing longest （3.5 a） continuous observation along the major deepwater passage of the Luzon Strait.
