Abstract： Based on the Princeton Ocean Model (POM), Levitus 94 datasets and weekly average of Sea Surface Temperature (SST) and wind data from NOAA satellites, a three-dimensional hydrodynamic model, which took into consideration of the M2 tide, was built and applied to simulate the annual cycle of temperature and circulation in the Yellow Sea and to reproduce the process of t he Cool Water Mass in the Yellow Sea (CWMYS). The results show that the uniform pattern and stratification pattern are from January to March and from May to November, respectively. The local thermo-structure is affected by the CWMYS and the Warm Current in the Yellow Sea (WCYS). The circulation is closely related t o the wind field in the Yellow Sea. In winter, the WCYS consists of two branches , the one in the west being its main current. In summer, the circulation is very weak, especially in the center of the Yellow Sea. This weak current region, en trenched at the bottom until November, is an important factor of the CWMYS.

摘 要： 海洋环流是海洋科学研究的1个焦点。本文首次建立了东中国海环流自适应数值模 型。由于所设计的自适应网格既与边界适应，又在水深变化急剧的东海陆坡处得以加密，从 而使坐标变换下的三维斜压模式克服了跨越陆坡计算这一难题，并以期获得更为精确的数值研究成果。该模型基于Lagrange时均观点，而非Euler观点。它可计算海域三维斜压流场， 从而得到其风生热盐潮致Lagrange环流。模拟结果与实测及现有的数值研究结果比较，合理可信。其中黄海暖流的起源问题，计算结果与传统观点相悖，而与近期实测结果一致。 本文为系列报道之首篇。

Abstract： Ocean circulation is a focus on researches related to marine science . In this paper, a self-adaptive numerical model of the circulation in the ECS( East China Sea) is established for the first time. Because the grids designed are self-adaptive at the boundaries and are denser where the water depth changes rapidly, this 3d baroclinic model can be used to solve the difficult problem of calculating circulation on the continental slope. The model is based on the Lagrangian timeaverage viewpoint, not Euler's. By using it the 3d baroclinic circulation in the ECS was calculated and the Lagrangian circulation induced by w ind, salinity and tide were obtained. Compared with the numerical results in exi stence and the observations, the results of this model is reasonable. Conclusion s about the origin of the Huanghai Sea Warm Current are made based on the result s. They are inconsistent with the traditional viewpoint, but agree well with re cent observations.

Abstract： The hydraulic resistance of gravity cage, which is cylinderical shap e with a perimeters of 50m and a depth of 8m, is tested by using a cage model in a flume tank. The results show that the hydraulic resistance of gravity cage is below 7 500kg, when the velocity of flow is lower tha n 2.5kn. The resistance of gravity cage is mainly caused by the section of the n et, which accounts for about 88% of the whole resistance, When the gravity cage is equipped with aplummet of different weight, the relation between hydraulic re sistance and velocity of flow is F=aV b, and the hydraulic resistance of gr avity cage increases with the increasing of the plummet weight. However, the inc idence that the weight affect on the cage resistance decreases along with the in creasing of the velocity of water flow.

Abstract: In this paper, the antihypertensive effects of fucoidan oligosacchari des prepared from Laminaria japonica on renovascular hypertensive rats (RHR) and related mechanisms are presented. Renovascular hypertensive rats (RHR) mode ls were made with a twokidney one clip assay and the effects of the fucoidan oligosaccharides at doses of 6.25,12.5, 25 and 50mg/kg were studied in renovascular hypertensive rats in the acute therapeutic experiment. Arterial bl ood pressure including systolic blood pressure (SBP) and diastolic blood pressur e (DBP), respiration and plasma angiorensinⅡ(AngⅡ) were measured respectively. The results show that fucoidan oligosaccharides can markedly reduce the arterial blood pressur e and plasma AngⅡ of RHR and the antihypertensive effects of fucoidan oligos accharides at high doses are similar to captopril. Moreover, the change of the r espiration of RHR is similar to that of their blood pressure. The respiration of RHR had the same change trend as blood pressure. These results indicate that f ucoidan oligosaccharides have good antihypertensive effects on RHR and one of the mechanisms underlying the antihypertensive effects might be that they can in hibit the production of AngⅡ.

Abstract: Chitosan C(MW=98KDa) and chitosan D(MW=1 130KDa) are formed into micr ospheres by the reaction between chitosan and TPPNa. Urease is immobilized onto the chitosan microspheres with glutaraldehyde. The chitosan microspheres have sm ooth surfaces and better mechanical intensity at the concentrat ion of chitosan 3% and C/D=5/1(w/w). Porous chitosan microspheres were formed by adding CaCO3 (chitosan/CaCO3=1/1,w/w) into the reaction system. The urease immobilization efficiency on smoothsurface chitosan microspheres and porous ch itosan microspheres is 51.5% and 68%, respectively. When the system reacted for 12 min, the urea (300mg/mL) conversion rate of the immobilized urease of smo othsurface chitosan microspheres and porous chitosan microspheres is 91.8% and 99.99%, respectively. The results show that the porous chitosan microspheres ca n improve both the immobilization efficiency of urease and the conversion rate o f urea.

Abstract: To observe the effect of Sargassum Hemiphyllum polysaccharides(SHP ) on the oxidative damage we detected the activity of superoxide dismutase(SOD) , catalase(CAT) and malonaldehyde(MDA) in the plasma and liver of radiated mice of 2 Gy γ rays. It is found that SHP(20mg/kg and 40mg/kg) can not only sign ificantly(P<0.01) decrease the MDA content but also significantly(P<0.01) increa se the activity of SOD and CAT in the plasma and liver in a dosedependent mann er. SHP(10mg/kg) also significantly increase the activity of SOD in the liver an d the activity of CAT in the plasma and liver of radiated mice. The results show that SHP have an inhibitory effect on lipid peroxidation and a free radical cle arance effect in radiated mice.

Abstract： Heterotrophic bacterioplankton are decomposers of organic material a nd secondary producers in marine ecosystems. They are abundant and dynamic membe rs of remobilization of organic carbon and regeneration of inorganic nutrients i n marine environments. Heterotrophic bacterioplankton productions are believed t o be limited by dissolved organic material，inorganic nitrogen, the temperature of water and the concentration of trace elements (e.g. iron). The grazing ratios of zooplankton are also important. The viruses may be important regulators of b acterioplankton biomass.

Abstract： The content and distribution of chlorophyll a (chla) and phaeopigm ents (phaa) in the sediments of the East China Sea and the Yellow Sea were inv estigated in October， 2000， and May， 2001． The content of chlorophyll a in t he surface sediment layer was also analyzed after incubation under different red ox conditions. The results show that the highest chlorophyll a in the surface se diment layer(0～1cm) of this region appears at station E4. The concentration of chlorophyll a in the surface sediment is 2.48μg/g in October and 3.01μg/g in May, respectively. Both chlorophyll a and phaeopigments decrea ses remarkably with depth， and are stable at a certain depth. There are several observed leaps in the vertical distribution of chlorophyll a and phaeopigments at some stations，it may be caused by biodisturbance and the environments change s. As the main degradation product of chlorophyll a， phaeopigments become the m ain type with the increase of depth. After incubation under nitrogen and oxygen conditions，the concentration of surface chlorophyll increases. Here we compare the total content of chlorophyll a in the sediments and in the water column. On the average of the 5 studied stations of the October cruise， the total chloroph yll a in the sediment accounts for 36.9% of the total chlorophyll a in the water column. But at E4, it is colse to that at the Changjiang River Estuary， and it s ratio is as high as 111.1%， This part of chlorophyll a should not be igno red.

Abstract： The largest coastal dunefield in China lies on the Qinhuangdao co ast from Beidaihe to the Luanhe estuary. The dunes is about 20～30m high commo nly, of which the tallest is 45m. There are four kinds of dunes found along the coast, including coastal foredunes, longshore dune chains, oblique dune chains and sand sheet. The sediments of the dunes is mainly composed of we llsorted medium and findgrain sand. The grainsize distribution of the san d dunes is characterized by slightly nagativeskewness and dowble bounce movi ngs. Highangle tabular crossbedding and lowangle wedge crossbedding are generally found on the crosssection of the dunes. Sand dunes often develop wh ere there is a large supply of sand, the shoreward and offshore winds are str ong enough to start the sand and there is suttieient open space. Proper measure should be taken to protect the natural scene of the coastal dunes.

(College of Marine Geosciences, Ocean University of China, Qingdao 266003, Chin a)

Abstract： Sedimentation during the stage of Chang6 depositio n was controlled by a lacustrine delta system. The Chang6 member is an import ant fingerbar reservoirsandstone in the Wangyao area of Ansai oilfield.Chang 6 reservoir in the Wangyao area mainly consists of finegrained sandstone and minor siltstone. The sandstones can be classified as compositionally immature a rkoses. The main diagenetic minerals of the sandstones include authigenetic clay minerals, calcite cement, quartz and feldspar overgrowth, albite and laumontite . The authigenic quartz overgrowths and microcrystals contain a variety of organic fluid inclusions that indicate the petroleum filling history. Secondary porosity has been created mainly by feldspar, rock fragment and laumontite dissolut ion. The dissolution mechanisim is closely related to organic acids and transfor mation of clay minerals in adjacent source rocks. Based on diagenetic events rel ated to temperature, the reservoir diagenetic stages can be classified into Asubstage of later diagenesis. The reservoir quality is controlled mostly by sedim entary microfacies and diagenesis. The distribitary channel and mouthbar sandbod ies are commonly of high porosity and permeability, whereas the front sandsheets may be of low petrophysical properties.

Abstract： A cancer diagnostic algorithm, combined with lightinduced autofluorescence spectroscopy using double excitation wavelengths, was employed for distinguishing between cancerous and normal gastric serosa. For emission spectra by 308nm excitation wavelength, the ratio between the area under 360～370nm and that under 465～475nm was calculated. In the same way, f or emission spectra by 337nm excitation wavelength, the ratio between the area under 380～390nm and that under 465～475nm was calculated. The canonica l discriminant function was used in the double excitation wavelength algorithm t o determine a dividing line between the normal and cancerous tissues. The result s showed that better performance up to sensitivity 94.4%, specificity 92.1%, and positive predictive value 91.9% could be achieved by using double excita tion wavelength. The present study can be useful as a basis for further investig ation in vivo autofluorescence measurement and analysis using double excitation wavelength.
