基于小世界网络的电动汽车市场接受度预测模型

基于复杂社会网络理论、消费者行为和消费者购买决策理论,构建了基于小世界网络的电动汽车市场接受度预测模型,并通过Netlogo软件仿真社会网络中消费者对电动汽车的接受过程.研究表明:电动汽车的市场接受度取决于消费者个体初始偏好和社会网络效应的共同作用,局部网络效应的影响大于全局网络效应;选择意见领袖为初始采用者、提高初始采用者比例、降低消费者购买意愿阈值等均会显著提高电动汽车的扩散规模和扩散速度.     

基于消费者选择偏好的可替代品订货策略

基于消费者选择偏好,建立了相应零售商利润-订单量的条件风险价值模型。以零售商利润为最优化目标,在市场总需求不确定时,考虑零售商风险偏好、消费者选择偏好及两种产品的可替代性,研究零售商的最优订货策略。研究结果表明,当产品订货量在一定范围时,产品替代性将失去作用:当两种产品总订货量在一定范围时,产品最优订货量随顾客偏好系数及产品替代系数的提高而增大,随替代产品顾客偏好系数和零售商风险规避程度的提高而减小:产品与替代产品间的顾客偏好系数差异越大,两产品总订货量越大。

考虑绿色偏好与产品替代率的新能源汽车供应链效益分析

目的 针对日益严重的环境污染问题,创新地提出将消费者绿色偏好、产品替代率等作为研究新能源汽车供应链效益的主要影响因素。方法 将两个不同汽车制造商和一个分销商组成的两级供应链作为研究主体,在主要考虑消费者绿色偏好、产品替代率等影响因素下,通过供求关系构建供应链各主体的利润函数模型,利用逆向归纳法对模型进行求解,进而利用maple软件对整体供应链各部分利润进行数值分析。结果 研究结果表明：新能源汽车制造商、分销商和供应链整体利润与消费者绿色偏好和产品替代率呈正相关,而对传统燃油车制造商而言,其利润与消费者绿色偏好呈负相关,与产品替代率呈正相关。结论 数值分析发现：当消费者绿色偏好和产品替代率较小时,产品替代率是影响新能源汽车制造商、分销商利润的主要因素,消费者绿色偏好是影响传统燃油车制造商和整体供应链利润的主要因素;当消费者绿色偏好和产品替代率逐渐增大时,消费者绿色偏好逐步成为影响新能源汽车制造商、分销商利润的主要因素,产品替代率逐步成为影响传统燃油车制造商、整体供应链利润的主要因素。     

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
