国民账户体系及逻辑关系解析

国民账户体系是以账户的形式描述国民经济运行过程——以资产负债存量为起点和终点的生产、分配、消费和投资的过程,主要由经常账户、积累账户和存量账户三大类账户组成。本文以联合国编著的1993年国民经济核算体系为蓝本,对国民账户中这三大类账户及其各账户之间的内在逻辑关系进行解析。正确掌握国民账户及其相互关系,可以对国民经济运行过程中生产、收入分配及消费、积累、资产负债等内容的脉络把握得更加清晰和准确。     

浅析心理账户对投资组合的影响

人的大脑中有一种心理账户,把实际客观等价的支出和收益,在心理上却划分到不同的账户中。由于心理账户的影响,用来构建投资组合最重要的工具,不同投资品种之间的相关性难以得到充分利用,所以普通投资者的投资组合往往是行为化的、非有效的。对此应买入多种类型的股票,明确选择投资品种的数量化标准,投资债券,以赚取市场的平均利润为投资目标等以构建有效的投资组合。     

我国国际收支的结构特点及其成因分新

进入20世纪90年代以来,尤其是从1994年至今,中国的国际收支出现了经常账户和资本与金融账户持续的“双顺差”（1998年除外,该年资本与金融账户为逆差）,这种情形在国际经验中并不多见。开放经济下这种“双顺差”的国际收支结构有其特征、形成原因,亦反映出我国宏观经济运行中存在的问题。

谈增值税会计处理中存在的问题及改进建议

税法规定，确定销项税额的原则与财务会计上确认销售收入的原则相一致，采用的是权责发生制。但作为与销项税额抵扣的进项税额，其确认采用的却是收付实现制。这使得同一计税基础实行两种不同的原则，同一时期的销项税额与进项税额不相配比，使得人们难以从销售收入同增值税的逻辑关系上判断出企业是否合理地计算并交纳了增值税，从而使会计信息的可比性和有用性大大降低。

环境与绿色国民账户

对于环境问题,现行的国民账户体系是要负一定责任的。这是由于现行国民账户在环境方面的缺陷造成的。建立绿色的国民账户体系是必要和必然的。那么具体来说现行的国民账户体系在环境方面的缺陷有哪些,建立绿色国民账户的方法是怎样的,绿色国民账户将会给经济带来怎样的影响是本文讨论的主题。     

从会计核算的角度探讨我国增值税的征管与转型

本文从应交增值税的核算角度探讨增值税的征收管理 ,认为应该把销项税额与进项税额的核算基础由现行的权责发生制改为收付实现制 ,从而有效控制偷、逃税现象 ,同时促进增值税税收征管的改革 ,使增值税征收管理的方式、手段更趋严密、科学。又从购进固定资产所支付的进项税额的核算角度探讨增值税制由生产型增值税转为消费型增值税 ,认为这种转型有利于提高企业产品的市场竞争力及西部大开发战略的实施等     

基金模式下养老金问题的研究

在基金模式下,构建了养老金问题基本模型,研究了养老金问题中主要涉及的参数、个人养老金账户发放因子和替代率水平,并得出在不同年龄退休时的平均余命.在此基础上计算了相应的个人养老金账户发放因子,并模拟出不同报酬率下的个人养老金账户的替代率水平.研究结果表明,应根据养老金的缴费年限及银行利率适时调整养老金账户发放因子,实现个人养老金账户替代率水平的提高,并提出了实施的具体方案.

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.     

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
