名词附缀——再论单音方位词的句法地位

汉语单音方位词有不同的用法,句法地位也有所不同。后置介词说、名词说都不能充分说明后置单音方位词的语音附着性。附在名词之后的单音方位词句法语义取宽域,保留名词的句法地位,语音具有附着性,具有名词附缀的句法性质。名词附缀的语音句法错配性,体现出词缀和词的双重特点。附着在名词后的单音方位词保留名词地位不是后置介词,方位短语不是介词短语,而是处所名词短语。处所名词短语跟一般名词不同,既能做主宾语,又能作状语,具有双重功能,这可以自然解释方位短语作状语的现象。并非只有介词短语才能作状语,汉语方位短语能用作状语,并不能证明就是后置词短语。语言成分常常具有双重地位和双重功能,需要综合运用语音、语义、句法手段确定语言成分的句法地位和句法功能。     

对英语中空语类现象的探讨

空语类（empty category）又译为空范畴或虚范畴，是乔姆斯基于上世纪七十年代末八十年代初提出的一个概念，在其管辖与约束（GB）理论中占有十分重要的地位。所谓空语类是在句法、语义表达式中存在，而在音系表达式中没有音系矩阵的成分（徐烈炯，1988：193）。文将着重论述什么是空语类，空语类PRO的分布特点及空语类的照应性等问题。空语类现象的研究对揭示语言的句法特征起着至关重要的作用。     

基于词类序列的汉语语句韵律结构预测

为完善计算机汉语语音合成,构建了韵律结构预测系统。该系统区分了现代汉语中韵律结构与语法结构存在对应关系和不存在对应关系的两类单位,采取确定韵律结构和调整韵律结构,分别处理这两类单位;考虑了"的"、"介词"等功能词在韵律短语预测中的作用;面向汉语文语转换应用的语句韵律词及韵律短语;只依赖语句的词类音节数序列等简单的文本信息。在107句语料上进行了测试。结果表明:韵律词预测正确率达95%,韵律短语预测正确率约81%,操作性较强。     

对科技英语中以which及“介词+which”引导的定语从句类型及翻译的探讨

在科技英语中,以which及“介词+which”引导的定语从句从表达的形式来看,有多种类型:有的从句和所修饰的词之间没有逗号分开,有的有逗号分开;关系代词which在从句中可作主语、宾语(动词或介词的宾语),有时还可作表语;有的定语从句和所修饰的词之间还可以被另一作定语的介词短语或动词谓语及其他成分隔开的;which前的介词可以是简单介词,也可以是短语介词,还可以是“名词(或代词)+of+which ”引导的;等     

语法隐喻在科技语篇中的体现形式及语篇功能

在韩礼德语法隐喻分类的基础上,研究了科技语篇中语法隐喻名词化和动词化的体现形式,发现科技语篇中存在两种特有的语法隐喻形式,即单个形容词和单个名词可以充当环境成分;语法隐喻在科技语篇中具有语篇衔接和语类功能。     

《最简探索：框架》下“被”的句法地位

“被”的句法地位众说纷纭,有“被”的介词说、动词说、双重地位说。在探讨这些观点长短得失的基础上,以句法特性为出发点,借鉴Chomsky最新《最简探索：框架》的相关假设,针对“被”的语类特征进行了尝试性分析。提出将“被”字分析成一个汉语言特有的、具有强名词性特征P-feature的功能语类。同时,通过对标准被动句生成过程的实例描述,验证了“被”字功能语类特征的假设。

汉英主语表示法的差别与翻译

汉语与英语的主语表示法差别较大。主要体现在动词作主语、形容词作主语、述宾短语作主语、主谓短语作主语、述补短语作主语、偏正短语作主语、“的”字短语作主语、同位短语作主语、介词短语作主语等方面。只有掌握两种语言各自特点，才能准确互译。     

英语中某些特殊的“否定”表达法

概括了英语中几种特殊的“否定”表达法:用动词、形容词、名词、连词、名词短语、介词、成语、修辞性问句、虚拟语气、双重否定。引用了大量例句来说明这些“否定”表达法。     

谈介词和介词短语的功能特点

一、介词及其功能特点在现代汉语的词类中,介词是用在词或短语(主要是名词和以名词为中心的短语)前面,合起来一同表示起止、方向、时间、处所、对象、原因等的词。     

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
