论古代常德沅澧人才群体的形成和特点

彭头山人和城头山人创立了常德远古时代领先的农业文明和城市，善卷在转向文治的德文化中发挥了重大的作用。楚人大量进入常德后，使常德在德文化的基础上形成了“惟楚有材”的格局。至明代，沅澧流域经济、文化教育的发展，形成了常德古代人才群体的高峰，并为常德近代以来人才群体的发展打下了基础。     

翘嘴鳜EST-SSR标记的开发及3个群体遗传多态性分析

为保护野生翘嘴鳜(Siniperca chuatsi)的种质资源以及遗传育种,本研究从翘嘴鳜的EST文库中开发微卫星并筛选出22对具有多态性的微卫星标记,对来自陆水水库(赤壁)和沅江流域(常德、怀化)的3个野生群体进行了遗传多样性分析.实验结果显示,这些标记在3个群体中均表现出了丰富的多态性;共检测到134个等位基因;各基因座观测等位基因数4～8个;平均等位基因数为6.090 1;观测杂合度0.675 4;期望杂合度0.748 7;多态信息含量0.701 0,表明3个翘嘴鳜群体在各检测位点中具有较好多态性.对数据进行F-检测,平均Fst值为0.038 3,说明群体间的遗传分化程度低;而群体遗传相似度和遗传距离的计算结果显示:常德和怀化群体的遗传相似度最大,遗传距离最小;而常德与赤壁群体的遗传相似度最小,遗传距离最大.这恰恰与翘嘴鳜群体的流域分布一致.     

丁未、戊申钦廉起义述评

丁未、戊申钦廉起义有着十分重要的历史地位,它为辛亥革命的成功积累了丰富的斗争经验.一是证明了在半殖民地半封建社会的中国,要取得民主革命的胜利,实行武装革命是正确的、完全必要的.二是两次钦廉起义是中国近代民主革命资产阶级与农民阶级实行革命联盟的早期典范.三是两次钦廉起义失败的教训,使革命者认识到,重视西南的战略和输入式革命的方法不合乎当时中国革命的具体情况.丁未、戊申钦廉起义,是资产阶级革命派发动和领导的武装夺取政权的斗争尝试,有力地推动了民主革命运动的发展.     

古巴在前进

保卫革命保卫祖国的偉大斗爭古巴深刻的人民革命的胜利已经两年零四个月了。在这些充满振奋人心的激烈斗争的日子里,英雄的古巴人民紧密地团結在以菲德尔·卡斯特罗总理为首的革命政府和革命力量的周围,坚定不移地以推进革命来保卫革命;使革命不断深刻化。“各国共产党和工人党代表会议声明”指出,摆脫了殖民主义压迫的国家,必须同帝国主义和封建主义残余进行坚决的斗争,把民族、反帝、民主革命的任务坚持到底;把本

建国初期中国共产党解决“三农”问题的历史考察与启示——以土地改革为中心

建国之初，农村凋敝，农业生产发展迟滞以至破产，农民生活极端困苦。为了解决“三农”问题，党和政府制定法令政策，领导广大农民开展了轰轰烈烈的土地改革运动。这是人民民主革命在军事斗争胜利后的又一场重要的阶级斗争和政治斗争，它解放了农业生产力，使农业生产得以恢复和发展，“三农”问题得到初步解决。但靠采取群众运动的方式来进行政治斗争和经济变革，从长远看来，是不可能从根本上解决农村、农业和农民问题的。

侵华日军实施常德细菌战之原因

1941年11月4日，侵华日军对常德实施了一次大规模的细菌战攻击。日军实施常德细菌战的原因主要是：细菌战是日本侵华政策的组成部分；日军企图占领常德这一华中地区军事重镇和交通枢纽；日军为了夺取常德这个洞庭湖“粮仓”。

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     

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
