中日能源合作中的俄罗斯因素

能源安全问题是东北亚国家共同面临的问题。目前的形势表明,能源正在成为东北亚各国关系和区域安全方面的新热点,它犹如一把双刃剑,既可能成为诱发东北亚国家间争夺的导火索,也可能成为促进东北亚国家合作的突破口。东北亚能源需求上升从能源需求角度看,中日韩三国能源需求对外     

东北亚区域能源合作的可行性分析

近年来东北亚区域成为世界上经济高速增长的地区,对能源的需求亦逐年增加。本文从俄罗斯、东北亚其他各国及各国之外对东北亚区域能源合作的可行性进行分析。     

东北亚科技发展高层论坛

作为东博会的主体活动之一，以“高新技术产业合作与发展”为主题的东北亚科技发展高层论坛于2005年9月21日举行．与会者分别介绍了本国（本地区）在东北亚区域科技经济合作的现状．并对未来加强东北亚区域各国（地区）科技合作进行了展望。[编者按]     

东北亚合作:“东北振兴”的机遇?——与柴瑜博士一席谈

温家宝总理在印尼出席东盟峰会时建议,将继续深入研究建立中日韩自由贸易区问题,并透露,明年将在中国举办中国“振兴东北”与东北亚合作研讨会。东北亚经济合作的开展将为我国东北地区的开发提供怎样的机遇?为此,本刊记者采访了中国社科院亚太所的柴瑜博士。     

东北亚经济圈发展现状及前景展望

随着经济全球化进程的加快,东北亚区域经济发展受到了更加广泛的关注。东北亚地区发展基础良好,经济十分活跃,各国经济互补性强,双边合作成效显著,开展经济合作具有很大优势。但同时也存在许多现实困难。比如,地区安全机制尚未确立;某些国家容易受外力影响;各国政府步调难以一致等等。目前,东北亚地区的经济合作明显落后于世界其他地区,这从另一方面说明,该地区的经济合作具有巨大的发展潜力。东北亚经济圈的建成,将促进东北亚各国的经贸发展,实现东北亚地区的和平、安全、稳定和繁荣。中国具有独特而重要的区位条件,在东北亚经济一体化进程中应发挥强大的推动作用。     

东北亚能源合作

当前我国能源特别是石油进口持续增加,能源安全面临着严峻的挑战,需要通过区域能源合作采保障我国能源安全。东北亚区城除我国外,既包括油气资源丰富的俄罗斯,又有缺乏油气资源但资金雄厚的日本和韩国,发挥各国优势加强东北亚区域能源合作,是防范我国和区域内其他国家能源风险、避免对能源资源恶性竞争的有效途径。     

2002年东北亚论坛在威海举行

五月的威海,风光旖旎,绿树红瓦,碧海蓝天。由中华全国工商业联合会、中国国际贸易促进委员会、中国光彩事业促进会、经济日报和山东省人民政府主办的东北亚论坛在威海市举行。东北亚各国政界、企业界、学术界的朋友,来到了这个美丽的城市参加东北亚论谈。5月2日上午,一曲《相聚东北亚》主题歌唱响在2002年东北亚经济论坛开幕式主会场大     

10＋3框架下的东北亚区域合作——兼谈对东北亚合作的几点新认识

东北亚地区的概念可以有两种理解．一是指亚洲的东北部地区．这样就包括了俄罗斯远东地区、中国东北地区、蒙古、朝鲜、韩国和日本共6个国家，其中，俄罗斯、中国都以部分地区入围“东北亚”地域概念。另一种是指东亚的北部地区。如果按“东亚”来划界，那么显然不包括俄罗斯。因为俄罗斯传统上届于欧洲国家，尽管它横跨欧亚两大洲。这样，“东北亚”概念就只包括中、日、蒙、朝、韩5个国家。这也可以认为是以国家来定位的一种概念。虽然从广义上讲，东北亚合作不能缺少俄罗斯的参与，但如果把东北亚看作是东亚的一部分，那么从现有的东亚合作机制来看，还没有包括俄罗斯。这里所说的“现有的东亚合作机制”就是指10＋3框架，即东盟10国和中、日、韩3国组成的中央政府一级的合作机制。朝鲜、蒙古作为东亚国家，只要它们有意愿，随时可以加入这一机制。     

“一带一路”建设不能少了朝鲜

正朝鲜似乎成了一块被人遗忘的角落。"一带一路"战略在周边独缺东北亚一块,形成了缺口和断裂。朝鲜是中国在东北亚推行"一带一路"战略的必经之道。中日韩三国合作已建立起以领导人为核心、20个部长级会议和60多个工作层机制为支撑的机制,却没有包括朝鲜。涉及东亚区域合作机制的"10+3"、亚欧会议、东亚峰会、APEC等等,也都没有邀请朝鲜参与。然而,朝鲜在地域上是东北亚的核心地区国家,在政     

建设“东北亚经济走廊”势在必行

正2016年4月29日,笔者参加了由中国公共外交协会和中日韩合作秘书处在钓鱼台国宾馆主办的"首届中日韩公共外交论坛暨2016年中日韩合作国际论坛"。中国外交部副部长张业遂到会致词,三国前政要、外交官、著名学者、社会名流等聚集一堂,深入研讨中日韩三国合作的重要性和发展趋势,会议透出的信息可以使人感受到中日韩三国进一步合作的浓浓春意。笔者深感:建设"东北亚经济走廊"势在必行。在"一带一路"倡议提出和推行的过程中,东北亚区域     

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
