基于(火用)参数的环境影响评价

基于火用概念讨论了和环境影响之间的内在联系,阐明了参数可用于度量排放物对环境影响的程度,介绍了系统排放的废弃物和废热火用计算模型,提出通过修正参考环境基准值来调整污染物值以反映污染物对环境影响程度的方法。将这种方法应用于排污计量及排污收费,经实例分析是可行的。     

完善基层环保机构排污收费工作的若干建议

排污收费制度是我国环境管理的一项基本制度，是依法实施环境管理的一项有效经济措施，排污收费制度实施20多年来，对于提高全民环境意识，筹集污染治理资金，促进企业污染治理、技术进步，加强环境保护的自身建设，强化环境执法，推动环境保护工作的全面开展都发挥了十分重要的作用，国务院已经颁布了《排污费征收使用管理条例》，国家有关部门发布了一系列配套的政策，达螳法规政策以控制污染物排放总量、改善环境质量、促进社会经济和环境协调发展为原则，在排污收费体制、标准、资金使用、管理体系与制度建设上进行了全面改革，在总量收费上取得了重大突破，实现了由超标收费向排污收费、由浓度收费向浓度与总量收费相结合、单因子收费向多因子收费、静态收费向动态收费的转变，明确了收支两条线的财政政策，完善了排污费的使用管理制度，这将对促进污染防治和生态保护，提高环境保护执法队伍的现代化水平，完成“十一五”环境保护计划发挥更大的作用。     

高速公路可变收费费率模型研究

高等教育学费标准的神经网络模型研究

在适当的假设下，建立起符合中国实际的收费模型，即BP神经网络模型，该模型的网络算法符合实际要求，并以此为参考，指导各个高校根据自身的实际情况，制定合理的收费标准，从而规范高等教育收费。     

2我国排污费征收标准将调整

近日，国家发改委、财政部和环境保护部日前联合发出通知，要求到2015年6月底前，我国各省（区、市）污水、废气主要污染物排污费征收标准将调整，同时实行差别化排污收费政策。
　　现行排污收费制度从2003年开始建立，已经实施11年之久。其中，污水类和废弃类污染物排污费征收标准分别为每污染当量0.7元和0.6元。此次调整后，这两项标准将分别调整为不低于1.4元和1.2元，翻了一番。     

高等教育多元化收费价格模型的构建

通过分析影响高等教育价格的主要因素及高等教育本身的多元性，基于“谁受益，谁付费”的市场经济原则，并兼顾教育效率与社会公平，构建了一种以高等教育成本为基础、高等教育本身的多元性为依据、生源地经济状况为参照的多元化收费价格CUSEE模型，并利用该模型计算了我国2003年度高校的收费价格，其结果与当年的实际情况基本相吻合。CUSEE模型克服了高校以往收费价格的单一、静态等不足，体现了高等教育本身的多样性，兼顾了效率和社会公平，其既可在宏观也可在微观上为高等教育的收费价格提供一种理论模型。     

高速公路收费模式的研究

提出了制定高速公路收费模式应遵循的三个目标：效益，收益和公平目标。结合沪嘉高速公路收费模式，从经济效益，财务收益和使用者效益分析角度，提出了制定和评价高速公路收费模型的程序和方法。     

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     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
