中图分类号

中图分类号是指采用《中国图书馆分类法》对科技文献进行主题分析，并依照文献内容的学科属性和特征，分门别类地组织文献，所获取的分类代号。文章一般标识一个分类号，多个主题的文章可标识多个分类号，其间用分号隔开。

《中图分类号》简介

根据CUJA—9018号通知的要求,从1991年第3期起,本刊开始在中文摘要及关键词后增加一项《中图分类号》。 《中图分类号》是依照《中国图书资料分类法》一书的分类法给每篇论文一个分类号。这是实现CUJA(China University Journal Abstract)所力求的“一次文献编辑与二次     

中图分类号在科技期刊论文中的标引检索分析

介绍了在科技期刊论文中标引中图分类号的原则及步骤,分析了中图分类号在标引论文、检索文献、分类统计中的作用,并探讨了目前科技期刊论文中中图分类号标引不当的现象,以及因其自身局限、普及不够、标引不当等造成的中图分类号检索弱化现象。指出了编辑人员应重视中图分类号的标引工作,加强相关知识学习,为期刊论文的族性检索和分类统计创造条件。     

中图分类号在科技期刊标引中存在的问题及标引的原则

科技期刊中中图分类号的标引存在着许多问题，如不重视中图分类号的标引、只看题名进行标引和标引不全面等．提出中图分类号标引时应遵循的原则：准确性原则、全面性原则、侧重性原则和归类性原则．同时提倡编辑们在标引中图分类号时应加强责任心，正确标引，以达到标引中图分类号的目的．     

《中国图书馆分类法》（第5版）存在的问题与建议

《中国图书馆分类法》在我国属于最有权威性及代表性的图书馆分类法体系,同时《中国图书馆分类法》也属于一种综合性很强的分类方法.对2010出版的《中国图书馆分类法》（第5版）进行了细致的分析,发现类名表述、类号划分及类目设置等方面都存在一些问题,针对这些问题提出了一些建议.     

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.     

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
