经济虚拟化催生经济泡沫

实体经济是大众就业的主渠道,是社会财富的主要来源,是科技创新的基础,是企业家孕育的摇篮。虚拟经济膨胀会淹没企业家精神。社会不事产业,弃实务虚,就业形势将更加严峻,中产阶层也就缺乏生长的土壤。一个沉湎于股票市场、热衷于房地产投机、倾注于网络游戏的国家与民族,长期来看肯定是没有前途与希望的,短期而言也易于遭遇危机。     

建筑经济与房地产经济

本文作者主要从房地产经济中界定了社会经济，建筑经济两方面，给出论述了经济形象。     

谈虚拟经济与实物经济

虚拟经济以虚拟资本为载体、是相对实物经济而言的信用制度高度发展与货币资本化的产物,是新经济的一种重要表现形式,在现代经济生活中的地位越来越重要,对整个经济的影响也越来越广泛、深入。从虚拟经济对货币市场的影响入手来分析虚拟经济对整个经济发展的负面影响。     

试论虚拟经济与实体经济

以虚拟资本为核心、以金融系统为主要循环依托的直接以钱生钱的虚拟经济,其特点可以归纳为以下几点:复杂性、介稳性、高风险性、依附性、周期性、增长性、无形性等。     

日本赶超经济的经济分析

20世纪90年代以来，日本的经济增长速度持续走低。通过对日本经济持续低迷原因的探讨，本文提出了“赶超后”的概念，认为日本经济所面临的问题是在实现经济赶超的过程中积累而成的，赶超经济既可以促进后发展国家工业经济的生成、发展和实现，也可以为后发展国家工业经济的持续发展遗留下许多不易化解的难题。这些问题一直困扰着已经实现了经济赶超目标的日本，本文将其称为“赶超后”现象。     

论建筑经济与房地产经济

房地产行业在近几年得到了飞速发展，也为我国经济的发展做出了极大的贡献，带动了相关产业链的发展。但是房地产经济的发展过快，造成经济发展存在问题，很容易出现经济泡沫。所以，接下来我们就来研究一下建筑经济和房地产经济发展之间的关系，希望能为经济发展提供一些建议。     

谈一谈虚拟经济与实体经济

虚拟经济与实体经济之间，存在着极其密切的相互依存、相互促进的关系。它们谁也离不开谁，至少在相当长的一段时期内会是这样的。     

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.     

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     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

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
