罗源湾春季营养盐分布及潜在性富营养化分析

根据2006年3月底对罗源湾进行的海洋化学-生物要素的调查资科,分析了罗源湾春季营养盐和叶绿素a(Chl-a)的分布特征,进行了潜在富营养化评价,讨论了影响罗源湾春季营养盐和Chl-a分布的主要因素及其相互关系.调查发现,罗源湾营养盐和Chl-a分布具明显的空间区域性,罗源湾内湾春季水体为氮氮限制中度营养水平.影响罗源湾海区P偏高的原因是多方面的,水产养殖是重要的因素.     

海洋环境安全:一种可持续发展的观点

联合国海洋环境保护科学问题联合专家组(GESAMP)是一个由八个联合国机构发起的科学顾问团体,它的报告和述评是各个联合国组织制定有关海洋政策和决策的基础.尽管GESAMP的观点近年来有很大进展,但在如何促进和改善保护海洋环境的行动等问题仍有它的局限性.本文提出了"海洋环境安全"的概念,以促进海洋环境保护和海洋资源的可持续利用,并讨论了海洋环境研究和海洋环境管理应采取的行动.

近岸海域抗生素污染状况的研究进展

抗生素是海洋环境中的一类新型污染物,由于其使用量的逐年增大导致污染程度的加深,对人类健康和海洋生态环境构成威胁.为了弄清近岸海域中抗生素的分布特点,减少残留抗生素对海洋环境的污染,保障海洋生态系统的健康发展,通过查阅资料,实际调查,样品比对等方法,研究了近岸海域抗生素的污染来源及分布特征,探讨了抗生素对海洋生态环境的影响,并针对我国海洋现状提出了今后的研究重点,主要包括以下四方面:(1)开展敏感区域污染状况调查,探讨抗生素污染物进入海洋的主要路径,开发降解去除抗生素的方法.(2)建立和完善低浓度抗生素含量分析方法,掌握海洋环境中抗生素的污染水平,弄清海洋环境中抗生素的时空分布特点.(3)研究不同种类抗生素在海洋环境中的行为归宿.(4)开展海洋生态环境风险评估,分析抗生素及其降解产物的毒性.     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach
