德惠断陷下白垩统碎屑岩储层特征及控制因素分析

德惠断陷下白垩统登娄库组、营城组、沙河子组储层物性差,勘探风险大.利用岩心观察、铸体薄片鉴定、扫描电镜分析、黏土X线衍射分析等方法,分析储层基本特征、储层成岩作用和控制因素.结果表明:德惠断陷下白垩统碎屑岩储层成分成熟度和结构成熟度较低,储层孔隙类型主要有残余原生孔、次生孔和混合孔,储层物性和孔隙结构较差;压实作用是导致储层物性变差的主要原因,溶蚀作用改善储层物性;纵向上发育2个次生孔隙带,主要形成于中成岩期,次生孔隙带的形成与有机质生烃排酸和断裂有关.研究结果为德惠断陷下白垩统进一步油田勘探提供地质依据,对其他地区类似储层研究有一定借鉴意义.     

市场机制下建筑节能相关利益主体博弈研究

充分发挥市场机制对节能产品的调控作用是市场经济的基本内容。通过对建筑节能市场发展中存在的相关问题研究,发现我国建筑节能市场的外部性和信息不对称性是产生问题的根源。全面分析建筑节能市场中政府、开发商、消费者以及其他服务组织等利益主体对市场培育的核心作用,通过构建政府与开发商、开发商与消费者之间的动态博弈模型,研究相关利益主体进一步完善建筑节能市场应采取的对策。     

高校图书馆参加“农家书屋”建设的思考与实践

高校图书馆在参与支持“农家书屋”的建设与发展中具有专业技术人才、信息资源等优势,可以通过对“农家书屋”管理员进行图书情报业务培训、协助“农家书屋”制定管理制度与开发自动化管理软件、组织高校教职工及大学生捐献图书与声像资料、组织大学生寒暑假“三下乡”和建设高校“读者协会”的社会实践基地来推动“农家书屋”的健康发展.     

析架空输电线路上倍容导线的选择

架空输电线路项目扩容改造,当采用倍容导线时,需在技术和经济上对倍容导线进行比较分析。文章对这种导线的种类、特性情况作了介绍,通过在220kV线路上对倍容导线的选择分析,为同类案例的处理提供了借鉴和参考。

"计算机网络技术与应用"课程教学改革与实践的探讨

“计算机网络技术与应用”是一门实践性很强的专业课程,不经过必要的实验教学是不可能达到教学目的,所以在教学过程中必须重视实验教学,注重学生实践技能的培养。而恰当选择实验内容,理论与实践相结合是做好实验教学的关键。     

Ehrenfeucht-Fraïssé games in finite set theory

In this article, with Ehrenfeucht-Fraïssé games we prove that Δ₁≠Δ₀ on BFR, which implies Δ≠Δ₀ on BFR, and thus solve an open problem raised by Albert Atserias in his dissertation (Δ₀,Δ₁,Δ are fragments of first order logic and BFR is a class of finite sets which in essence is equivalent to a class of finite pure arithmetic structures with built-in BIT predicate).     

Learning in an Ambient Intelligent World: Enabling Technologies and Practices

The rapid evolution of information and communication technology opens a wide spectrum of opportunities to change our surroundings into an Ambient Intelligent (AmI) world. AmI is a vision of future information society, where people are surrounded by a digital environment that is sensitive to their needs, personalized to their requirements, anticipatory of their behavior, and responsive to their presence. It emphasizes on greater user friendliness, user empowerment, and more effective service support, with an aim to bring information and communication technology to everyone, every home, every business, and every school, thus improving the quality of human life. AmI unprecedentedly enhances learning experiences by endowing the users with the opportunities of learning in context, a breakthrough from the traditional education settings. In this survey paper, we examine some major characteristics of an AmI learning environment. To deliver a feasible and effective solution to ambient learning, we overview a few latest developed enabling technologies in context awareness and interactive learning. Associated practices are meanwhile reported. We also describe our experience in designing and implementing a smart class prototype, which allows teachers to simultaneously instruct both local and remote students in a context-aware and natural way.
