黄海海域陆相中生界地震反射特征及靶区优选

利用前人对黄海海域油气勘探成果，作者对北黄海盆地，南黄海盆地北部坳陷陆相中生界进行了研究。结果认为：黄海海域陆相中生界分布广、厚度大、具有良好的生、储、盖组合，是该区下步油气战略性调查的首选目标。并提出北黄海陆相中生界油气勘探应以东部凹陷为主，同时兼顾中部凹陷。南黄海北部坳陷近期油气勘探重点应选择北部凹陷和加大东北凹陷的研究力度。南黄海南部坳陷陆相中生界油气勘探重点放在南五和南七凹陷。

A finite element model of interaction between viscous free surface waves and submerged cylinders

This paper describes the simulation of the flow of a viscous incompressible Newtonian liquid with a free surface. The Navier–Stokes equations are formulated using a streamline upwind Petrov–Galerkin scheme, and solved on a Q-tree-based finite element mesh that adapts to the moving free surface of the liquid. Special attention is given to fitting the mesh correctly to the free surface and solid wall boundaries. Fully non-linear free surface boundary conditions are implemented. Test cases include sloshing free surface motions in a rectangular tank and progressive waves over submerged cylinders.     

东海大规模赤潮危害影响的实验研究——对黑褐新糠虾和卤虫的毒性效应

The effects of Prorocentrum donghaiense,Karenia mikimotoi,Alexandrium catenella,the causative species of Harmful Algal Blooms in the East China Sea,on the survival and growth of Neomysis awatschensis and Artemia salina were investigated.And the toxicity of eleven strains of Alexandrium----A.lusitanicum(AL-1)、A.minutum(AM-1)、A.spp.(A-K)、A.tamarense(ATHK,ATCI02,ATCI03,AT5-1,AT5-3,AT-6)、A.affine(AS-1,AC-1) to the two above organisms were compared. The results showed that P.donghaiense and K.mikimotoi had no adverse effect on the survival and growth of N.awatschensis and A.salina at 96h.However,the survival rate of N.awatschensis and A.salina declined linearly with the increasing density of A.catenella,and the 96h LC₅₀ for N.awatschensis and A.salina was 4500 and 460 cells/mL,respectively, Five strains of Alexandrium----A.spp,A.lusitanicum (AL-1),A.tamarense(AT5-3,AT-6) and A.affine (AS-1)at the density of 4000cells/mL and 96h had no adverse impacts on N.awatschensis. But other six strains of Alexandrium a.Tamarense(AT5-1,ATHK,ATCI02,ATCI03),A.affine(AC-1) and A.minutum(AM-1)decreased the survival fate of N.awatschensis significantly. Two strains of Alexandrium----A.lusitanicum(AL-1) and A.tamarense(AT-6),at the density of 500cells/mL. had no adverse effects on A.salina in 96h;while the other Alexandrium strains all had adverse effeets on the survival of a.salina, A.salina could increase its length with the increasing density of P.donghaiense,K.mikimotoi and A.luxitanicum. The results indicate that P.donghaiense and K.mikimotoi have nio significant effect on the survival of crustaeean zoop lankton in a short period. But several Alexandrium specised/strains could influence the survival of crustacean zooplankton likely by non-PSP substances. A.salina is shown to be more sensitive than N.awatschensis as test organisms to harmful species.

Hydrocarbon Potential of Pre-cenozoic Strata in the North Yellow Sea Basin

The North Yellow Sea Basin ( NYSB ), which was developed on the basement of North China (Huabei) continental block, is a typical continental Mesozoic Cenozoic sedimentary basin in the sea area. Its Mesozoic basin is a residual basin, below which there is probably a larger Paleozoic sedimentary basin. The North Yellow Sea Basin comprises four sags and three uplifts. Of them, the eastern sag is a Mesozoic Cenozoic sedimentary sag in NYSB and has the biggest sediment thickness; the current Korean drilling wells are concentrated in the eastern sag. This sag is comparatively rich in oil and gas resources and thus has a relatively good petroleum prospect in the sea. The central sag has also accommodated thick Mesozoic-Cenozoic sediments. The latest research results show that there are three series of hydrocarbon source rocks in the North Yellow Sea Basin, namely, black shales of the Paleogene, Jurassic and Cretaceous. The principal hydrocarbon source rocks in NYSB are the Mesozoic black shale. According to the drilling data of Korea, the black shales of the Paleogene, Jurassic and Cretaceous have all come up to the standards of good and mature source rocks. The NYSB owns an intact system of oil generation, reservoir and capping rocks that can help hydrocarbon to form in the basin and thus it has the great potential of oil and gas. The vertical distribution of the hydrocarbon resources is mainly considered to be in the Cretaceous and then in the Jurassic.     

Metabolites from mangrove endophytic fungus Dothiorella sp.

Mangroves are special woody plant communities in the intertidal zone of tropical and subtropical coasts. They prove to be a natural microorganisms and new metabolites storage. In the study of mangrove endophytic fungi metabolites, four new compounds, Compounds 1, 2, 3 and 4, as well as a known octaketide, cytosporone B (5), are isolated from an endophytic fungus, Dothiorella sp., HTF3. They all show cytotoxic activities. The elucidation of these structures is mainly based on 1D/2D NMR and ESI-MS spectral analyses.     

海洋天然气水合物的地震识别方法研究

天然气水合物作为21世纪新的自然能源将为人类的生存发展服务。20世纪60年代证实，俄罗斯西伯利亚的麦索亚哈气田为典型的天然气水合物形成的气田，70年代又在海底发现了固体天然气水合物岩样。1971年，RStoll首先将地震剖面中的似海底反向层解释为海洋天然气水合物存在的标志，后来被深海钻探证实，从此地震方法成为大面积研究天然气水合物的重要手段。天然气水合物既是潜在能源，也是影响环境和形成灾害的因素之一，因此，研究天然气水合物是人类在21世纪的重要课题。探讨海洋天然气水合物的地震识别方法，由于这项工作刚刚起步，还没有做出具体的成果，在此只能根据我们仅有的工作和参照国外分开的出版物，以及出国访问得到的有关资料进行分析，提出我们的一些基本设想，与各位专家探讨。     

Non-Simultaneous Failure of Ice in Front of Multi-Leg Structures

Because the multi-leg jacket structure is the major type of offshore structures in the Bohai Sea, the study of non-si-multaneous failure of i鏴 on multi-leg structures is important. However, the non-simultaneous failure has not been consid-ered in engineering design until now, obviously resulting in costly design and notable waste. To resolve this problem, this paper, by means of analysis of experimental data, calculates the coefficient of the non-simultaneous failure for the double-pile structure, the square four-leg structure, the single-line multi-pile structure, and the conical structure, respectively, and provides some reference criteria for engineering design.     

用含氯化镉培养液培养塔胞藻的生物学效应

在塔胞藻培养液中加入不同浓度的CdCl2,然后分析了培养在各种处理和对照组的塔胞藻后代.结果发现,随着镉离子浓度的升高,细胞的生长繁殖量和体积在前2轮(9d为一轮)培养中均明显降低,而在第3轮培养时,细胞的繁殖和大小接近常态.随后对处理后多种细胞内含物含量进行了分析,显示出:随着培养液中镉离子浓度增高,细胞内的蛋白质、叶绿素含量均明显下降,而可溶性糖、核酸的含量与对照相比变化不大.
