阿根廷央行救市效果不彰,比索呈断崖式下跌

正阿根廷货币比索汇率8月30日对美元汇率单日跌幅超过11%,并一度突破40∶1心理大关。为稳住汇率,阿根廷央行当日卖出3.30亿美元外汇储备,这是阿根廷央行连续第三天大举抛售外汇储备。今年以来,比索对美元汇率跌幅已超过50%。阿根廷比索今年首次大跌出现在4月底,在阿政府与国际货币基金组织(IMF)达成贷款协议后,比索汇率曾短暂稳定。不过,近期受政府部分债务展期     

阿根廷的金融危机与资本外逃

阿根廷是美国赞扬的金融自由化典范,银行证券业向外资开放的力度大,但其爆发金融危机造成的破坏也格外严重。阿根廷金融危机与经济全球化进程,特别是与金融开放和资本市场自由化密切相关。阿根廷吸引跨国银行投资,对本国金融体系的稳定造成了极其恶劣的影响,资本外逃给民众存款造成了重大损失。中国应积极吸取阿根廷的教训,慎重对待外资收购、兼并和MBO,特别是"入世"后银行证券业的开放,更好地维护本国经济金融安全,防范风险。     

新经济形势下汇率波动会我国出口的影响——基于面板数据的实证检验

我国在2005年汇率改革后,进一步放开了汇率波动幅度.2007年爆发的全球金融危机更是加剧了汇率震荡.选取2001年-2008年间中国与12个主要贸易出口国或地区的面板数据,分为两个对称时段,运用经典引力模型实证检验了新经济形势下汇率波动对于出口的影响.研究发现,在2001年到2004年时段,汇率波动对出口的影响并不显著,但从2005年到2008年的新经济状况下,汇率波动的增加明显抑制了出口.因此,建议在金融危机新背景下,政府应加强汇率管制以求稳定,增强本国出口商的信心,暂时不宜进一步放开汇率.     

关于人民币汇率的政策取向问题

亚洲金融危机爆发以后 ,在人民币汇率政策取向上存在着两种截然不同的观点 ,一种是人民币汇率应贬值的观点 :一种是人民币汇率应保持稳定的观点 ,我国加入WTO(世界贸易组织 )在即 ,人民币汇率的稳定将面临着巨大的压力 ,同时也对人民币汇率政策提出了新的要求。我国货币政策的最终目标是保持货币币值的稳定     

论汇率的内外稳定机制及其协调

在钉住汇率机制下，发展中国家汇率的内外稳定机制都有偏差。抵御或化解金融危机的关键在于汇率内外稳定机制的协调，其合理的路径是正确设定汇率变化的目标区，加强区域性的贷币合作以及限制投机资本的无度流动。     

对我国汇率制度改革的探析

根据美国经济学家克鲁格曼针对新兴国家金融危机的“三元悖论”论,分析我国汇率制度存在的一些问题,认为目前我国应实行汇率目标区,盯住一扌监子货币的汇率制度。     

关于人民币汇率的政策取向问题

亚洲金融危机爆发以后，在人民币汇率政策取向上存在着两种截然不同的观点：一种是人民币汇率应贬值的观点，一种是人民币汇率应保持稳定的观点，我国加入ＷＴＯ（世界贸易组织）在即，人民币汇率的稳定将面临着巨大的压力，同时也对人民币汇率政策提出了新的要求。我国货币政策的最终目标是保持货币币值的稳定。     

东业金融危机的成因,影响及启示

分析了东南亚金融危机的根本原因，从出口商品竞争力，外资流入增幅，人民币汇率的稳定三方面阐述了东南亚金融危机对中国经济的影响，指出进一步完善人民币汇率的形成机制，积极推进经济增长方式的转变，切实加强金融监管的必要性。     

1997——2000年人民币汇率政策的效应分析

汇率政策作为宏观经济政策之一,对一国的经济发展有着重大的影响。亚洲金融危机爆发后至今中国一直采取人民币不贬值的汇率政策,这种汇率政策的采取在当时有着较强的政治意义与经济基础,并给中国带来了巨大政治效应,但也给中国的经济发展带来诸多不利之处。     

浅谈人民币汇率制度改革

由美国次级贷危机引发了全球金融风暴,国际金融货币体系必然面临新的调整与变化,人民币必将走向更加灵活的汇率制度,而此次金融危机的发生也给人民币汇率形成机削更加市场化的改革提供了新动力和新契机。由此,人民币汇率制度改革便成首要议题。     

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.     

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

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
