谱写科普惠民新篇章——北京市科委创新型科普社区建设实践探索

社区是社会公众日常生活的集中地区,也是开展科普工作的典型和有力阵地。一说起社区科普活动,许多人的印象仍停留在或是"唱唱跳跳"的文艺演出、或是养生保健知识讲座等几种简单的形式。但对业内人士来说,社区科普如何做到规范和长效是个难题。为贯彻落实《北京市科学技术普及条例》,提升公众科学素质,北京市科学技术委员会(以下简称市科委)于2007年启动了创新型科普社区的创建工作。如今,5年多的时间过去了,创新型科普社区创建工作进展如何,科普社区建设又取得了哪些成果呢?     

我国科普场馆建设的现状与思考

怎样打造高素质的科普志愿者队伍

科普志愿者是重要的科普力量,全国科普志愿者队伍基本形成,但是,科普志愿者队伍素质有待于提高.怎样打造高素质的科普志愿者队伍,该文提出关于建立高素质科普志愿者队伍的建议:一是多渠道、高标准地发展高素质科普志愿者队伍,二是在科普活动中壮大高素质科普志愿者队伍,三是建立科普志愿者队伍的管理与培训机制,四是积极举办各种类型的科普活动,五是搭建科普平台,发挥科普志愿者作用.     

培育增强国民创新意识 推进科普事业新发展

本文提出科普要适应国家创新体系的建设，并简要论述创新主要是知识创新；培育增强国民创新意识是当前科普工作的一项重要任务，努力开展有关培育增强国民创新意识的科普活动。     

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
