浅谈财务软件的二次开发

<正> 随着企业现代化管理对财务会计要求的不断提高和计算机技术的飞速进步,会计工作向电算化方向发展已成为不可逆转的潮流。商品软件的日臻完善,使得大多数企业放弃自行开发软件的计划而选择购买商品软件,应该说,这是符合多数企业实际的明智选择。然而,由于商品软件的通用性,它不可能为每个用户的特殊需要提供具体的解决方案。为了满足用户的特殊需要,许多软件都提供了扩展功能,用户可以根据本企业的具体情况,对商品软件的功能进行扩充,或者利用其他通用软件如数据库软件编制功能模块,与商品软件挂接起来,从而使软件更适合本企业的特殊要求,功能更强,操作更方便,这     

稠油难采储量二次开发技术研究

杜68块于1993年投入开发,为典型稠油油藏,地质储量836×10~4t,受早期认识及技术条件限制,动用地质储量仅为199×10~4t,未动用储量达到637×10~4t,占总探明储量的76.2%。随着二次开发技术的进步,通过应用"分区、分层、分井型"的三分一体的开发模式,重新进行了井网规划,新动用地质储量235×10~4t,区块日产由27t上升到最高的96t,采油速度由0.17%上升到最高0.65%,取得良好的开发效果。在盘活区域储量的同时,为同类油藏的开发积累了宝贵的经验。

水平井热采提高二次开发效果

针对二次开发开发中存在的问题,通过研究国内外多种水平井底水脊进临界产量解析模型,发现低粘度油藏流体驱替更加均匀,底水脊进趋势比高粘度油藏更小,寻找出了解决问题的办法。在此基础上利用CM G软件的ST AR S模型来模拟流体油、气、水的流动规律,研究二次开发水平井的热采效果和合理的注采参数,实际应用结果表明水平井热采能经济有效提高油井产量,提高二次开发水平。     

基于Navisworks API碰撞检查的二次开发

Navisworks软件是一款应用广泛的主流BIM软件,支持项目相关方整合、分享和详细审阅三维设计模型,具有强大的多专业协同设计、施工进度及工艺模拟、三维大场景展示和碰撞检查等众多实用且成熟的功能。在进行BIM模型碰撞检查时,往往需要按照碰撞点属性将所有碰撞点进行分组和快速查看等操作。文章基于Navisworks API,通过二次开发,研究更方便地进行碰撞检查结果的后处理功能方法,从而提高工作效率。

基于ANSYS的桥式起重机主梁三维有限元分析

以50 t/16 t桥式起重机为研究对象,采用有限元软件ANSYS对起重机主梁结构进行了应力分析。结果表明,主梁腹板截面突变处存在严重应力集中,降低了桥式起重机的承载力。     

基于ANSYS Workbench的桥式起重机主梁有限元分析

预测桥式起重机主梁疲劳寿命,需判断主梁应力集中区域,以期为确定应变片检测位置提供理论指导。使用ANSYS Workbench对50/10t桥式起重机主梁进行多工况有限元分析,得到主梁各工况应力云图。分析结果表明,最大应力出现于主梁两端腹板与下盖板连接处以及下盖板两端弯曲处,这些区域易发生疲劳受损。     

基于ANSYS Workbench的风力机流固耦合分析

利用ANSYS Workbench软件对2kW的风力机进行流固耦合分析,得到风场风速、叶片所受风压、叶片变形、应力应变等有限元分析结果。同时对叶片本身、叶片在风场中静止及旋转情况下进行模态分析,并进行比较。ANSYS已将流体软件CFX整合到Workbench中,利用Work-bench对风机进行流固耦合分析可在软件内部完成多物理场数据传递,方便实用。得到的风场信息、叶片应力云图及叶片的模态分析为叶片的优化设计及研发工作提供直接数据,从而减少产品开发周期,降低开发成本。     

International legal norms governing development of the orbit/spectrum resource

Resource development is the process of dispersing concentrated values. International law relating to resource development establishes objectives for value dispersion and puts forward rules by which these objectives may be attained. The geostationary orbit and the electromagnetic spectrum are two store-houses of value, or resources, coming under increasingly vigorous international control. The author first describes geostationary satellite communications as the dispersion of values concentrated in the geostationary orbit and in the electromagnetic spectrum. He then addresses the objectives of international satellite communications policy and the relative effectiveness of relevant legal rules in implementing those objectives.

Value-focused thinking about strategic management of radio spectrum for mobile communications in Korea

Radio spectrum has become an increasingly vital part of the telecommunications infrastructure and economy of a country. As spectrum management grapples with increasingly complex decisions in the 1990s, clarifying the basic values of the spectrum management will become more important. This study uses multiattribute utility theory as a basis for obtaining value judgments regarding strategic management of radio spectrum for mobile communications and applies it to a specific case study of Korea. To structure and quantify the basic values of spectrum management, we elicited strategic objectives, then refined and structured them into a hierarchy. We developed attributes and derived a utility function to illustrate value trade-offs at the strategic level. The implications of the results for addressing a range of strategic issues are also discussed. We found that the work and results can provide valuable insights and decision opportunities for virtually all major decision making in spectrum management for mobile communications in Korea.     

软塑包装发展现状及加入WTO后面临的形势

软包装(Flexible Package)是指在充填或取出内装物后,容器形状可发生变化的包装。一般用纸、纤维制品、塑料薄膜、铝箔、复合材料等制成。塑料软包装(又称软塑料包装)是指用塑料薄膜或塑料复合材料进行的包装,具有质轻、柔软、废料少、占有空间少、成本低以及成本有效性高(单位重量包装的体积和重量)等优点。所以,用途广泛,除了用于包装食品、医药和纺织品外,还可用来包装玩具、日用品和小五金用品等。     

Secondary level engineering professional development: content, pedagogy, and challenges

The design of this study was a multiple case study conducted to examine the knowledge, pedagogical principles, and challenges involved in providing engineering-oriented professional development for teachers at the secondary school level. A set of criteria was used to identify five representative projects for analysis in the US. A variety of tools and processes were used to gather data including on-site observations, interviews, focus groups and document reviews. Results of the study indicate that engineering professional development tends to be based on work focused on curriculum development and implementation. Given the distinct design orientation of engineering, it is not surprising that the focus of engineering-oriented professional development tends to concentrate on engaging activities, with a primary focus on process rather than content. A key outcome of this study was an observed lack of a clearly formulated and articulated conceptual foundation for secondary level engineering. Regarding pedagogy, the researchers identified a heavy emphasis on modeling and applied learning. At the same time, the researchers observed a lack of emphasis on reflection and analysis of the pedagogical processes and techniques used to shape teachers’ ability to teach engineering to their students. The findings of the study also include concerns raised by teachers as they engage in engineering professional development. These include concerns about technical knowledge, particularly with the use of specialized software applications and other tools, as well as with practical issues such as time, resources, and availability of appropriate curriculum.
