低渗透气田经济极限储量界限研究

根据盈亏平衡分析,结合天然气开发企业的特点,考虑了收入、成本费用、投资等经济参数,建立了天然气经济极限储量评价模型。利用模型,通过试算得到了在一定内部收益率的条件下,天然气价格、井深与经济极限储量之间的关系,同时探讨了不同内部收益率下的经济界限值。选择了某低渗透气田的10个井区进行了实例分析,把这10个井区根据经济效益的好坏分成了3类,最后利用这10个井区的计算结果进行回归,得到了含气面积与经济极限储量成幂指数关系的结论。因此,根据一个井区的井深和含气面积就可以粗略的估算经济极限产量和经济极限储量,为天然气经济效益储量评价方法提供了一种新思路。     

中国省际经济增长“资源诅咒”的实证分析

针对我国大多数资源型地区经济发展水平与资源贫乏地区之间存在强烈反差的现象,在"资源诅咒"假说框架下,利用中国29个省1997—2006年的面板数据,实证分析了自然资源与经济增长之间的关系及其传导机制.结果表明:丰富的自然资源确实对经济增长产生了"资源诅咒"效应;自然资源主要通过削弱资源型地区的资本投入、教育投入、研发投入及第三产业发达程度这几种传导途径来制约资源型地区的经济增长.     

吉林省碳排放影响因素分析及与经济增长的脱钩研究

定量研究省域层面各因素对碳排放的影响程度,以及分析经济增长与碳排放的关系,是完成"十二五"和2020年碳强度下降指标的关键所在.以吉林省为例,运用STIRPAT随机模型,采用有偏估计岭回归方法对人口、经济、技术等因素对碳排放的影响程度进行了模拟,并检验了碳排放与经济增长是否存在环境库兹涅茨曲线关系;同时,引入脱钩指数法对碳排放与经济增长之间的脱钩关系进行了分析.结果表明:经济增长对碳排放的相对影响程度较大,是碳排放的主要影响因素;经STIRPAT模型检验,经济增长和碳排放之间未出现环境库兹涅茨曲线关系;经济增长与碳排放之间处于相对脱钩状态,这也从另外一方面验证了目前两者之间不存在环境库兹涅茨曲线的假说.

基于MFA的兰州市经济增长与环境压力关系变化分解分析

基于物质流分析方法,采用以物质投入与消耗为表征的环境压力函数,结合“修正后的Laspeyres方法”并运用结构分解分析模型,分析了兰州市1990?2004年经济增长与环境压力之间的时序关系及其变化趋势和各驱动因素对它的影响程度。结果表明：随着兰州市经济的快速增长,直接物质投入与国内物质消费总体呈上升趋势,由物质投入与消耗所产生的环境压力主要是由经济增长过程中自然资源的消耗所致。人口因素和经济增长因素对环境压力的增大具有正向效应,技术因素对它则具有负向效应,人口因素对它的影响程度相对较小且比较稳定,而经济增长因素与技术因素的影响更为显著。

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

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
