帐蓬空间的一点注记

设ｆ（ｘ）是Ｒ＾ｎ上的可测函数，ｕ（ｘ，ｔ）＝ｆ＊ｐｔ（ｘ）为ｆ的Ｐｏｉｓｓｏｎ积分，定义算子Ｆ（ｆ）（ｘ，ｔ）＝ｔ（θｕ（ｘ，ｔ）／θｔ）。在本注记中我们首先给出一则反例以说明Ｆ不是Ｌ＾∞（Ｒ＾ｎ）到帐蓬空间Ｔ＾∞的有界算子，然后证明了Ｆ却是ＢＭＯ（Ｒ＾ｎ）到Ｔ＾∞的有界算子。它补充、完善了Ｃｏｉｆｍａｎ－Ｍｅｙｅｒ－Ｓｔｅｉｎ的结果。

C_3A 的 Al-O,Ca-O 键与水化活性关系的量子化学研究

通过量子化学的ＳＣＣ－ＤＶ－Ｘα计算方法，分别研究了Ｃ３Ａ分子结构中２种ＡｌＯ４四面体和３种ＣａＯｘ（ｘ＝６，６，９）多面体的价键特性与活性。原子净电荷、键强、电子态密度、ＥＬＵＭＯ以及ΔＥ（ＬＵＭＯ－ＨＯＭＯ）等的计算结果表明：与水反应时，多面体活性大小顺序为Ｃａ（４）Ｏ９＞Ｃａ（１）Ｏ６（或Ｃａ（３）Ｏ６）＞Ａｌ（１）Ｏ４＞Ａｌ（２）Ｏ４。Ｃ３Ａ具有高水化活性主要与弱的Ｃａ－Ｏ键和空洞缺陷有关。

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
