不同教育程度的上海居民对世博会影响感知的调查分析

在上海居民实际调查结果的基础上，对上海世博会影响感知维度的16个主要评价指标进行实证分析，并根据被调查者的教育程度加以细化辨识。从调查数据的分析结果来看，教育程度在上海世博会影响感知的各个评价指标中，对多数评价指标存在影响，并有一定的规律性，即评价结果与教育程度有一定的对应性，教育程度是影响感知评价指标的重要影响因素；而教育程度对另一些评价指标有影响但无规律性或者无影响，其评价结果不存在较大差异。上海世博会影响感知正面评价的比例是较高的，而且教育程度的增加在一定程度上可以促成对举办大型活动的支持态度。     

消费者TV家庭冲动购物的激励因素

以TV家庭购物和冲动购买为研究基础，分析冲动购物的激励因素，通过检验设定的问题来确定其影响力。分析有一次以上TV家庭购物的303名消费者的调查资料，得出：（1）分析产品激励因素对专卖商品和流行商品的影响，结果表明，激励冲动购物只对流行商品有影响。（2）在促销激励因素中，提供赠品的激励和扩大信用卡打折期限的激励对冲动购物都有一定影响，后者影响更大。（3）价格激励因素中，大幅度降低商品价值的激励比合理的价值激励对冲动购物影响更大。（4）情境激励因素特性表明，引导销售激励比限量销售激励影响更大。（5）消费者TV家庭购物视听关联特性表明，看TV时间长比与有伴看电视对消费者冲动购物影响更大。

培养基成份对链格孢霉胞外蛋白酶的影响

本文研究了培养基成份对链格孢霉（Alternaria atternata)胞外蛋白酶形成的影响，发现，培养基成份对链格孢霉胞外蛋白酶的形成与活性有明显影响。链格孢霉只有在含1%酪素的培养基里才能形成胞外蛋白酶，否则不形成胞外蛋白酶，硫酸镁（MgSO4)对其蛋白酶活力有明显正向影响；磷酸氢二钾（K2HPO4）对其蛋白酶活力有明显负向影响；硝酸钠（NaNo3)对其胞外蛋白酶的形成具有明显负向影响。

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
