主数据集成：打破信息共享的壁垒

在信息化产业高速发展的今天，企业信息化建设已经日趋成熟。但如何解决各部门、组织之问存在的信息孤岛现象，让各组织实现信息、资源的流通。使企业各部门协同起来、形成更为强大实用的系统．已成为了许多企业当前面临的最大圃扰。而对数据进行有效的焦成管理，可谓增强企业竞争力的必然选择。     

企业IT部门成本构成及管理目标

随着信息技术的发展和管理理念的进步，各种各样的企业信息化项目接踵而来，企业资源计划(ERP)、客户关系管理(CRM)、供应链管理(SCM)及企业流程再造(BPR)等等，国内各种企业争相花巨资对企业进行信息化改造，成立专门的IT部门，设立CIO，仿佛搭上信息化快车，企业便可以高枕无忧地进入新经济时代了。     

企业信息化的思考

企业的信息化建设的现状喜中有忧,忧的是存在诸多问题企业信息化建设缺乏整体规划,未能充分认识清楚企业信息化建设与企业自身业务运作之间的关系,有些企业信息化起步早、投入大、失败多,产生惧怕风险情绪,企业信息化建设缺乏针对性,不清楚企业信息化建设必须与企业基础信息资源建设同步,缺乏对工业化、信息化、信息化建设和信息产业的正确认识。企业的信息化建设涉及企业的方方面面,方案的规划设计,要充分考虑到企业对各类信息的具体需求,一般采用分步完成企业的信息化建设。     

面向中小制造企业ERP系统开发

信息化是企业发展的必由之路,ERP软件的性能直接关系到企业信息化建设的成败。中小制造企业由于其管理的不规范性、系统化程度不足及资金的有限性,大型ERP系统并不适合他们的需求。本系统以企业资源的进销存管理为核心,兼顾供应商、客户等相关资源建立了一套完善的企业资源监管ERP软件。系统的业务流程由客户订单驱动,各决策部门根据企业内部和市场客户的资源情况对合同进行评审,而后签订合同,制定周密的生产计划进行有效的管理,组织安排生产,实时准确的反馈生产销售情况,为决策提供及时准确的信息,对企业物流、资金流、信息流进行一体化管理,建立企业决策完善的数据体系和信息共享机制,以实现效益的最大化。     

浅谈加强企业档案管理信息化建设

企业档案管理信息化建设是企业参与国民经济和社会信息化的具体体现,也是企业档案部门进一步深化改革,推动科技进步,提高服务效率的必然选择。近年来,常州科研试制中心有限公司在档案管理信息化建设方面做了很大努力,也取得了一定的成绩,但是与目前企业对信息高速发展的需求相比,企业档案信息化建设还比较滞后,严重影响企业档案资源的开发利用,实现不了资源共享的目的。结合工作实际试图分析企业档案管理的现状及存在的问题,探寻加强企业档案管理信息化建设的有效途径,使档案资源得到更好的开发利用,为企业的正确决策提供有力支持。

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
