罗密欧与哈姆雷特:两种人格类型的表现及演变

从罗密欧到哈姆雷特，无论是从社会学的角度还是从心理学的角度，都存在着一脉相承的联系。从社会学的角度看，显示了人主义的发展历程；从心理学的角度看，从外向型人格到内向型人格，显示了人物从简单到复杂、从幼稚到成熟的成长心路。     

简论北宋时期河南书院的办学特色

北宋时期河南书院的办学特色灵活多样：从书院性质上看，有民办，也有官民合办；从院址布局上看，注重环境的优美和文化底蕴的深厚；从分布上看，面广点多；从发展规模上看，“校”大生众；从教学特征上看，“门户开放”，自由讲学；从人才培养上看，求知求实。     

例说极限思想的巧妙应用

当一个变量无限接近一个定量时，把定量可看作此变量，这种从有限到无限的思维方式就是极限思想。极限思想实际上是特殊值法的延伸，它提供了从变量的无限变化中研究趋势的数学方法，使得我们从有限中认识无限，从近似中认识精确，从量变中认识质变成为可能。灵活运用极限思想，可以避免复杂运算，探索解题思路。

计算机的昨天、今天和明天

从1946年世界上第一台电子计算机ENIAC问世以来，计算机科学以其他科学技术无法比拟的速度迅猛地发展。50多年来，从ENIAC到‘Deepblue’；从昔日的‘APple’到今天的Pentium—11；从第一个操作系统CP／M到现在的Windows95；从手编指令到简洁方便多样的编程工具；从单一的数值计算到绚丽多彩的多媒体、网络世界，计算机从机房走进办公室，走进了千家万户，这一切无疑说明了由于计算机能够部分地代替或延伸人类的脑力劳动，使得它无论从量的方面，还是从质的方面都迅速地改变着人们的生活和工作。同时，日新月异的计算机科学技术，极…

我国古代美观念的演化

这个题目大，涉联面广，问题复杂，原可按时代先后或纪事本市那样演述，而这样就难免冗长、呆板，亦难以从中展示其规律性的东西。拙文拟从一个“大”字来做文章，从这个视角试加观照，粗浅些、简略些；但却可从中行到一个大致的眉目及规律性。可分为以下三章加以演述。－“羊火”与“羊人”的美观念古代部族社会，尤其是羊同腾部族，人们吃羊穿羊、祟羊赞羊，从物质到精神，都离心开羊。羊在古代就是美或美好的征象。“美”从“羊”，其初又《说文》训之为甘，甘指美食而言。在古代，羊最易于繁养，羊肉成为人们的主给之膳。“膳”从“羊”…     

2005,与创新一同走过

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
