人——管理信息系统中的重要因素

通过对MIS开发普遍失败的原因分析，重点说明了以往在MIS的开发和使用中人的因素所存在的问题。针对我国目前在MIS建设中忽略各种人员对MIS开发成功的影响而产生的问题，提出了应对的措施与建议。     

一种通用MIS授权方法

简要介绍了在实际开发MIS系统时所采用的一种MIS操作授权方法，该方法易于实现，不受具体开发和运行环境的限制，具有一定的实用价值。     

管理信息系统中人的因素

通过对MIS开发过程中人员需求与能力分析,说明了在MIS的建设和发展中人的因素的重要性,探讨了MIS专业人员应具备的素质.针对我国目前在MIS建设中忽略各种人员对MIS开发成功的影响而产生的问题,提出了应对措施,认为管理者、技术人员、使用人员应提高认识通力合作,这是提高企业管理信息系统开发质量的关键所在.     

管理信息系统开发策略的探讨

针对当前企业普遍存在着管理信息系统(MIS)的开发难以达到预期效果的实际，指出其原因不是简单的技术问题，而是系统开发的方法；分析了MIS开发中普遍存在的一个基本问题，即在MIS建设中系统的最终目标和内容常常难以确定，从而提出应采用原型法来开发管理信息系统，并用平稳安排、整体控制、用户参与等方法来组织与控制开发过程，同时还要做好系统管理人员的选拔、培养和系统中有关标准、规范的制定等系统开发的基础性工作。

中小型供电企业管理信息系统建设浅探

介绍了供电企业管理信息系统(MIS)建设的预期目标和建设方向,分析了目前MIS建设应用中存在的问题,提出了供电企业MIS系统的建设策略。     

信息可视化技术的发展及应用

随着计算机技术的日益发展和计算机应用的不断深入,对企业级的管理用户来说,传统的MIS技术对提高企业管理水平和质量已不起主导作用,尤其是在某些行业,如交通,电力、广电等系统,传统的MIS系统在那些涉及到业务数据的管理上往往显得力不从心。传统的MIS系统提供给用户的几乎是千篇一律的数值数据,用户面对的除了报表还是报表,这些“铁面判官”一样的数据无疑限制了人们主观能动性的充分发挥。因此,一种功能强大的或者说是基于可视化的信息管理系统的建设已经成为信息系统建设的必然。     

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.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

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
