大学校园流行语的词语特征

语体具有习得性，这种习得性又具有渐进性、阶段性和终身性。大学阶段语用主体口头语的共体性特征主要表现在词语上，具体体现在小团体专用或创造词语、专业术语通用化、异语(多数是汉语和英语)混合运用、借用方言词语、对旧有词语作新的解释、创造新词语、词语包含了多种修辞格等方面。     

英语中的性别歧视

男女不平等是人类社会一直难以根除的顽疾。即便是在英美等西方发达国家，女性遭受歧视的现象也比比皆是。本文通过分析英语中与女性相关词语的语义特征、降格使用、非对称现象以及女性用语特点等，揭示了作为文化载体的英语是如何反映了英美社会对女性歧视的传统和现实。     

英语“量词”初探

英语语法书中没有把“量词”单独列为一个词类，但在具体的语言使用中，“量”这一概念的表现形式却异常丰富而活跃。本文拟就英语中“量调”的种类，“量”的表现手段及其语用、语义特征进行粗略的探讨。

俄汉词的语用信息对比

从俄汉词的语用信息特征在词法、句法及俄汉词的语用信息和语义信息交叉三方面入手,分析对比俄汉词中的语用信息。依据说话人对某种事物或现象所表示的评价态度,即从说话人对说话对象的态度、说话人对客观事实的态度、说话人对所说内容的态度三个方面分析俄汉词的语用信息的异同,揭示了词语中所含有的反映本民族文化、历史背景和生活习惯的信息。     

扩展语义相似情感词的文本情感分类方法

针对文本情感分类中情感语义特征利用不足、特征降维效果欠佳等影响分类效果的问题,提出了一种通过扩展语义相似的情感词以及引入词语间统计特征的高精度网络评论情感分类方法.该方法利用神经网络Skip-gram模型生成词嵌入,通过词嵌入相似性度量将语义相似的词语扩展为情感特征;再利用词语间的统计特征进行特征降维;通过多个弱分器加权构建Adaboost分类模型实现网络评论情感分类.基于酒店评论和手机评论公开测试集进行实验,结果表明其情感分类的正确率分别达到90.96%和93.67%.方法扩展语义相似情感词有利于丰富文本情感语义特征,引入词语间的统计特征有更好的特征降维效果,可以进一步提升文本情感分类的效果.

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

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.

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.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。

Exciton Seebeck in Molecular Systems

Various applications relevant to the exciton dynamics,such as the organic solar cell,the large-area organic light-emitting diodes and the thermoelectricity,are operating under temperature gradient.The potential abnormal behavior of the exicton dynamics driven by the temperature difference may affect the efficiency and performance of the corresponding devices.In the above situations,the exciton dynamics under temperature difference is mixed with
