摘要：屏风在居室中除了起到划分空间的作用,还有强烈的装饰效果。设计屏风时,既要考虑房间的整体风格,又要考虑屋主的生活习惯,在家里放置一款精致的屏风,不仅可以摆脱空间的单一性,还能为居室带来无限生机和雅趣。目前,屏风无论在材质、造型或色彩方面都比较丰富,为家居营造不同的艺术情调与文化氛围。

摘要：5V逻辑标准的时代正在过去。含有最新一代的处理器或ASIC的印制电路板组件需要多种电压向逻辑电路供电。这种印制板组件通常需要下述几种电压:为标准逻辑和接口电路供电的5V,为处理器或ASIC供电的3.3V或2.9V,为总线端接器供电的1.2-2.5V。除此之外,通常还需要为通信电路提供±12V或-5V。

摘要：研究以"国家生态补偿试点"的盐城国家级湿地珍禽保护区作为案例,从生态补偿对象的角度研究了生态补偿的政策设计。根据对保护区附近288户农户的实地调查数据,研究采用选择实验法识别了农户对不同生态补偿政策方案的偏好情况。通过计量分析发现:补偿政策设计中补偿水平、合同年限、退出合同的权利、环境绩效等补偿政策属性显著影响农户参与意愿,其中合同年限与退出权利对参与意愿影响最为显著。基于以上发现,研究讨论了补偿政策设计中不同的属性安排,特别是设置退出权限等措施对盐城生态补偿政策的成本有效性、可持续性及实施效果的潜在影响,为政策设计提供相应的实证基础。文章还计算了各个属性的接受意愿价值,并分析了潜在参与者的个人及家庭特征,为补偿的价格设定提供了相应的参考。

摘要：Over last few years, web services, Java 2 and XML have provided the cheaper means for trading partners to make use of EDI. It is now possible to share data with less reliance on expensive dedicated EDI networks. The second comes the realization that Product Definition can be reused by virtually all business processes downstream. This has made collaborative product development a practical reality. These technologies have enabled effective implementation of Product Lifecycle Management (PLM) Solutions. This paper presents a literature review about PLM solutions, looking at its definitions, through to its need and scope of applications. It also presents the most generally envisaged architecture, explaining as to how it may be looked at and what it is expected to deliver. At the end it examines the market trend and revenue growth over recent years including future trends for the most prominent vendors pitched in the field of PLM solutions.
