苏北盆地中古生代油气勘探具有50年的历史,在收集前人资料分析基础上,对苏北盆地和黄桥二氧化碳气田及朱家墩天然气田生储盖体系的地质特征及成藏要素分别进行了对比,分析了典型成藏模式;认为苏北盆地虽然只是苏北—南黄海盆地古、中、新生代盆地的一小部分,但其幔源"古生新储"二氧化碳气田和常规"古生新储"天然气田的发现对于海域南黄海盆地极具现实意义。  相似文献   

赤点石斑鱼人工配合饵料中蛋白质最适含量的研究   总被引：11，自引：1，他引：11  

陈学豪  林利民  洪惠馨 《台湾海峡》1995,(4)

本文探讨了不同蛋白质含量的配合饵料对赤点石斑鱼（Epinephelusakaara）生长的影响。通过60d度验得出：在各配合饵料组中，蛋白质含量为49．52％的试验的相对增重率（46．84％）体长相对增长率（15．96％）、蛋白质效率（60．35％）和饵料转化率（29．85％）等均为最佳。配合饵料组鱼体肌肉营养成分（蛋白质、脂肪、氨基酸和鲜味氨基酸）也均优于对照组，而更接近野生鱼。经回归方程分析，赤点石斑鱼人工配合饵料中蛋白质最适含量为48．37％～49．24％。  相似文献   

Characteristic analysis on oxygen isotopic tracer in the East China Sea and waters to east of the Ryūkyū-guntō     

Hong Ashi  Yuan Yaochu 《海洋学报(英文版)》1995,14(3):371-381

Samples of O isotopic tracer were mlleMed at Sections P₃,P₂₅,P_cM-t/2-E and P_CM-1/2.w in both the Fast China Sea and the area to the east of the Ryūkyū-gunto during October-November,1991.Analytical results of the δ¹⁸O are as follows: (1) In the Kuroshio area,the δ¹⁸O isolines are almost parallel to the 200 m isobath.The value of δ¹⁸O is negative and reaches minimum mt the main axis of the Kuroshio,and increases on both sides.(2) In the Taiwan Warm Current (TWC) area there is a high δ¹⁸O tongue extending to the northeast.(3) In the area near the coast,the distribution of δ¹⁸O isoline shows that the Changjiang River runoff diffuses seaward and the land-ocean isotopic effect from the nearshore to the offshore.(4) The values of δ¹⁸O are from -1.0×10^-3 to -0.5×10^-3 in the shelf.(5) There is a low mre of δ¹⁸O value(<-1.6×10^-3) at the 600 m layer in the Kuroshio area,which is quite in accord with the existence of a low salinity mre (S G 34.30) between the 600 and 800 m layers in the same area.Finally,the mrrelations of the δ¹⁸O with the salinity and temperature,the upwelling and so on are discussed.  相似文献   

海湾扇贝肝素样多糖分离方法的研究     

王长云  管华诗  林洪 《海洋与湖沼》1995,26(S1):66-69

于1992年1月-1993年2月，对从海湾扇贝中提取获得的糖胺聚糖（GAG）用乙醇和溴化十六烷基三甲铵（CTAB）分级分离，并对所得制品用琼脂糖凝胶电泳和高效液相色谱验证，以研究一种简便、快速的分离提纯方法。结果表明，扇贝GAG水溶液在乙醇量60％时分离获得的级分，其GAG－GTAB给合物再用2.0 mol/LNaCl溶液解离得到的主要级分，琼脂糖凝胶电泳和高效液相色谱均显示出单一区带，红外光谱类似干肝素的。证明这一提纯过程是一简便、快速的分离提纯方法。  相似文献

VERIFICATION OF INTERNAL WAVES IN OFFSHORE AREAS BY MEANS OF CURRENT OBSERVATIONS     

束星北  耿世江  顾学俊  孙洪亮  王祯祥  赵俊生 《海洋学报(英文版)》1986,5(2):165-172

Based on the shear effect of internal wave currents in stratified fluid, the necessary condition for the possible existence of an internal wave and the sufficient condition under which there will be no internal wave are deduced starting from the continuity equation of incompressible fluid. The above two conditions are verified by the measured results from vertical current meter arraies at some observation stations in the Bohai Sea and the South Huanghai Sea. In the treatment of measured results, first of all, the tidal period components are separated from the measured currents by Fourier-analysis method, and then the internal wave currents of tidal period from the tidal period components in the light of some considerations. The analytical results of observed currents are well consistent with theoretical analysis. Furthermore, one can also deduce some features of internal waves therefrom. Consequently, it is concluded that the observation from a vertical current meter array is an important means to verif  相似文献   

海沧邻近海域表层沉积物中重矿物研究   总被引：3，自引：0，他引：3

Current status of bacteriological parameters and DOC/POC in Xiamen coastal waters   总被引：2，自引：0，他引：2  

Khalid Maskaoui  Tianling Zheng  Huasheng Hong  Zhiming Yu  Zhong Hu  Yun Tian  Lizhe Cai 《海洋学报(英文版)》2003,22(3):443-451

The surface and bottom waters samples were collected from six locations in Xiamen western sea. The quantified estimation of bacterial production (3H-thymidine method) and observation of bacterial heterotrophic activity (14C-glucose method) have been made in order to have a better understanding of the role of marine bacteria and their activities. The results showed that the mean value of bacterial heterotrophic activity was 9×108 cells/(L.h) in the surface waters and 2.6×108 cells/(L.h) in the bottom waters. The mean value of bacterial production was 38×108 cells/(L.h) in the surface waters and 7.1×108 cells/(L.h) in the bottom waters. The relationship between bacterial production, heterotrophic activity, POC and DOC measured during this survey were discussed. The good understanding of the relationship between bacteria activity and total coliform was addressed.  相似文献   

西太平洋暖池变异及其对西太平洋次表层海温场的影响   总被引：9，自引：0，他引：9  

陈锦年  何宜军  孙树远  许兰英  宋贵霆  张艳慧 《海洋学报》2002,24(3):35-44

应用热带太平洋上层XBT温度资料,分析研究了西太平洋暖池区(0°～16°N,125°～145°E)上层海洋的变化特征以及与西太平洋次表层海温场之间的关系.研究表明,西太平洋暖池区的垂向温度存在显著的年际变化,尤其在次表层(120～200m)的变化最为明显.西太平洋暖池区的次表层冷暖信号明显早于西太平洋次表层的海温异常.分析发现,西太平洋暖池区的海温异常是导致整个西太平洋次表层海温场变异的关键区,当西太平洋暖池区的次表层冷暖信号加强时,3～4个月后西太平洋海温场出现大范围的冷暖异常.  相似文献   

厦门港浮游植物对磷酸盐吸收速率的研究   总被引：12，自引：1，他引：12  

洪华生  戴民汉  黄邦钦  李文权 《海洋与湖沼》1994,25(1):54-59

用无载体32P同位素示踪测定海水中浮游植物和细菌吸收磷酸盐速率的方法，对厦门港浮游植物和细菌进行了研究。结果表明，厦门港海水中吸收磷酸盐的主体是浮游植物（几乎占100％），平均吸收速率为4．28×10－5μmol／（L·s），并且存在着晚秋＜冬＜初春的季节变化，培养实验的结果表明吸收速率的季节变化主要是由于种类更替和温度效应所致。  相似文献
