Acta Oceanologica Sinica 2008年第z1期27卷 31-45页

A high resolved two-dimensional linear global diagnostic model combining with the dynamical calculation is used to calculate velocity field in the South China Sea(SCS). The study of model results shows that eddy diffusion does not change basic structure of circulation in the SCS and does not change the direction of invasive water, but changes the value of transport considerably especially in straits. The velocity field is not changed whether the wind stress is considered or not. This result shows the circulation is largely determined by a density field which well records most of the important contribution of the wind stress effect. Potential vorticity is calculated to testify the dynamics of the model results. The result shows that a good conservation of the nonlinear PV. This indicates most effects of the important nonlinear processes are well recorded in density and the nonlinear term is negligible so that the simplified model is reliable. The model results show the water exchanges between the SCS and open ocean or surrounding seas. Cold deep water invades through Luzon Strait and Warm shallow water is pushed out mainly through Karimata Straits. The model results also reveal the structure of the circulation in the SCS basin. In two circulations of upper and middle layers, a cyclonic one in the north and an anti-cyclonic one in the south, reflect the climatologic average of the circulation driven by monsoon. In the deep or bottom layer, these two circulations reflect the topography of the basin. Above the middle layer, invasive water enters westward in the north but the way of invasion of Kuroshio is not clear. Below the deep layer, a current goes down south near the east basin ,and invasive water enters in the basin from the west Pacific.

It is very appealing that 5-hydroxymethylfurfural（HMF） is electrocatalytical oxidized as 2,5-furandicarboxylic acid（FDCA） linking to non-classical cathodic hydrogen（H2） ***,the electrocatalysts for electrocatalytic HMF oxidative reaction（e-HMFOR） have been facing low Faradaic efficiency（FE） and high water splitting ***,we propose a strategy of the NiSeO3@（CoSeO3）4heterojunction by constructing a Co-Ni paired site,where the Co site is in charge of adsorbing for HMF while the electrons are transferred to the Ni site,thus giving the NiSeO3@（CoSeO3）4heterojunction superior electrocata lytic performances for e-HMFOR and water *** optimizing conditions,the NiSeO3@（CoSeO3）4heterojunction has high conversion of 99.7%,high selectivity of 99.9%,and high FE of 98.4% at 1.3 V,as well as low cell voltage of 1.31 V at 10 mA cm-2in 1 M KOH+0.1 M *** study offers a potential insight for e-HMFOR to high value-added FDCA coupling water splitting to produce H2in an economical manner.
