由于PPP模式下大型体育场馆项目实施周期长、经济技术复杂等原因,导致项目实施过程中的不确定因素较多,所以项目的风险因素识别极易产生遗漏.本文通过对各种风险识别方法的比选,采用WBS-RBS方法对此类项目全寿期过程进行风险因素识别.而后,首先对大型体育场馆项目进行了WBS分解;在此基础上,对此类项目进行RBS分解,识别出此类项目的系统和非系统风险因素.最后,对识别出的风险因素进行释义,希望能够为此类项目的风险管理选择合适的方法提供依据.  相似文献

近年来,国内大型煤炭企业纷纷选择向下游延伸产业链,现已形成了煤焦化、煤电化、煤油化3条产业路径;但是,煤炭企业产业链延伸风险管理的现状不容乐观.煤炭企业产业链风险管理,实质是针对多项目的风险管理,对风险因素的发生呈现灾害链式效应的特征.对煤炭企业产业链延伸风险管理应从多项目管理角度进行阶段划分,按照项目组合、项目集和单一项目分层进行管理.项目组合风险管理可依循基本管理模式进行.在此基础上,针对煤炭企业在产业链延伸过程当中可能遇到的风险,提出了一般性对策,以有效地预防、识别、降低和规避煤炭产业链延伸的经营战略风险.  相似文献

 煤层气产业战略效益是指煤层气产业发展对经济社会的整体贡献,本文从国家能源供需趋势和煤层气产业自身发展条件两个方面对其影响因素进行了讨论.影响中国煤层气产业发展及其战略效益的宏观因素包括经济状况、煤炭生产、洁净能源生产和环境保护三大方面,未来的经济状况是一个不确定因素,未来能源需求注定持续增长,发展新能源和低碳技术将刺激天然气(含煤层气)生产和消费大幅度增长.就细观层次而言,煤层气产量是产业战略效益的核心考量,受到煤层气资源条件及其探明程度、抽采方式与抽采技术、资金投入等因素的影响.中国的煤层气资源非常丰富,但资源探明程度低,煤层气地质条件复杂,既有战略效益释放的巨大空间,又对开发技术创新提出了更高的要求.抽采技术发展水平决定着煤层气产业战略效益可实现的程度,研发重点在于围绕提高煤层气地面单井产量和矿井抽采率两个核心,发展适用于各类地质条件的开发技术.煤层气开发前期投资大,投资风险高,资金回收期长,需从国家层面完善鼓励政策,构建多元化投融资平台.  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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-  相似文献

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-  相似文献

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  相似文献
