地理学的实在:一种漂移着的系统   总被引:1,自引:1,他引:0  
分析了地理实在的“确定性”和“不确定性”两个特征及其统一的可能性,讨论了地理实在的构成及区域地理系统的空间漂移,提出“自由的”时间空间尺度的论点。  相似文献

“实在”是一个表确认性的语气副词,本文通过大量的语料收集,着重探讨了“实在”句的句式特点、语义内含和出现的语用环境,得出“实在”句一般包含有主观感情色彩,强调经人们反复尝试而最终确认的一种思想过程,并提出对外汉语语气副词教学的两点想法。  相似文献

区域品牌“搭便车”行为的博弈分析与治理路径   总被引:2,自引:0,他引:2  
当产业集群形成区域品牌之后,区域品牌具有一定范围的非排他性的公共物品的性质,集群内企业中的个体搭便车行为就会给产业集群的区域品牌经营带来风险。本文对区域品牌使用中存在的“搭便车”行为进行了博弈分析,并探讨了产生区域品牌“搭便车”行为的原因,最后,提出了治理区域品牌“搭便车”行为的路径依赖。  相似文献

地理学实在中的差异性、整体与局部的相对性以及时空不确定性,使得地理事件在理 获得意义有所区别的表现和解释,基于此,提出了“多元性参照描述系”的概念,当人类的“和谐”观,应与人类多元的生存和解释方式对映。  相似文献

事物是一切哲学的根本前提和核心。近代西方哲学的主旋律就是探讨有关事物的诸问题。黑格尔在唯心主义可知论的前提下探讨了辩证事物观,认为事物是作为关系存在的。黑格尔“关系”理论具有深刻的科学性。马克思主义批判地继承了黑格尔的观点,我们应该从辩证事物观角度理解列宁的物质观。  相似文献

虚拟不只是一种技术术语,更是现代人的一种存在方式。从虚拟之“虚”、虚拟之“真”、虚拟之“在”三个层面可以看出“虚拟实在”的形上意义。  相似文献

行政区经济的博弈分析   总被引:3,自引:0,他引:3  
行政区经济作为一个过渡性质的经济类型,随着社会主义市场经济的建立.必然走向区域经济一体化.本文论述了行政区经济的涵义及其特点,并通过一个博弈模型来解释行政区经济形成是地方政府间博弈的结果,并提出了走出这种非合作博弈“囚徒困境”相关的建议.  相似文献

菲勒斯逻各斯中心主义中,意义建立在排斥的基础上,这种根源于二元认识论中主客体对立的意义生产构成了女人和其他少数族裔被边缘化的基础,因此受到女性主义的质疑。后者建构了“神圣”的理想,这种理想由于虚拟认知的促进将会早日实现。  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

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-  相似文献

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-  相似文献

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  相似文献

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  相似文献

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of  相似文献
