叙事与经验——以田中禾的小说为例

小说写作不是现实的摹本,但是,小说也不是和现实无关的虚构。小说写作和作家的个体经验密切相关。从田中禾的作品中可以看出,当作家的生存和社会节拍同步的时候,因为作家的个体经验与社会群体经验天然契合,作家的作品也就更容易获得社会认同。但是,这不意味着作家应该忽略其独特性的个体经验,而专门寻求能获得大众认同的宏大叙事来进行书写——如果缺乏作家独特的个体经验,这种宏大叙事往往不能带有感人的力量。     

记叙文中时间信息加工的机制

运用探测方式和自然阅读方式,考察记叙又中时间信息加工的内部机制,包括3个实验,探讨不同跨度的时间信息对后续事件的即时整合和先前信息记忆通达的影响结果发现:当考虑默认的时间序列时,强印象假设(the Strong Iconicity Assumption)可以很好解释记叙又中时间信息的加工;当考虑事件的场景持续时间时,场景理论(the Scenario Account)则能做出很好的解释;然而,当考虑场景内外的时间跨度时,强印象假设和场景理论都不能做出合理的解释,而本又提出的经验模拟假设(the Experiential Simulation Hypothesis)能做出合理的解释     

文学:“生活经验版“与“心灵经验版“

数学教师经验学习过程模型的构建

概念是数学知识的重要组成部分。数学的学习过程,就是不断建立各种数学概念的过程。本文介绍Malinen和Jarvis的数学概念学习、经验学习过程模型,并对模型的每一部分作详尽的阐述。利用经验学习理论研究教师经验学习过程,可以帮助数学教师转变已有的不正确的数学概念的观念,能够更好地构建并指导学生的二次经验,加深对数学概念的理解。     

论邓小平理论的主题

“什么是社会主义，怎样建设社会主义”是邓小平理论的主题，其实质是如何发展生产力并在此基础上实现社会全体成员的共同富裕。十一届三中全会以来，中国共产党坚持解放思想，实事求是思想路线，立足社会主义初级阶段的基本国情，以马克思主义宽广眼界观察世界，在改革开放和社会主义现代化建设实践中创立了建设有中国特色社会主义理论，制定了党在社会主义初级阶段的基本路线和基本纲领，第一次系统地初步解决了什么是社会主义，怎样建设社会主义的问题，并取得了许多宝贵的经验。

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
