浅谈厦门国家会计学院工程静压管桩断桩的原因及对策

结合厦门国家会计学院第一期工程PHC管桩基础施工中出现较多断桩的实际情况,从地质、勘察和施工三个方面分析厦门环岛路一带山前地区预应力管桩断桩的原因,提出应采取的对策,并应用于项目第二期工程建设中,提高了桩基施工的合格率。     

七窍皆通 上海嘉定新城紫气东来景观带湖心岛茶室

上海嘉定新城紫气东来景观带湖心岛茶室给人的最大印象或许就是其开放性和通透性。文章通过对这个建筑设计推演的阐述,说明了这种开放性和通透性的来源。     

基于CGCS2000大地坐标系的海岛测量控制网建立方法探讨

当前我国对海岛资源的逐步开发、利用日益迫切,海岛测量变得十分重要。本文主要介绍了海岛测量过程中建立2000国家大地坐标系（CGCS2000）控制网的方法,论述了从框架ITRF2000转换到框架ITRF1997的方法和过程,并用象山县旦门山岛为例做了验证,结果表明利用该方法快速建立四等GPS控制网是可行的。     

菲律宾西萨马岛AMPI矿区铝土矿床开采技术条件研究

通过对菲律宾西萨马岛AMPI矿区水文地质、工程地质及环境地质特征的实地调查、测量及综合研究,认为该类型矿床为以大气降水充水为主,水文地质条件简单;以松散岩类和可溶岩类为主,工程地质条件复杂性中等;地质环境质量良好,勘查类型属开采技术条件简单的铝土矿矿床。     

Security assessment for intentional island operation in modern power system

There has been a high penetration level of Distributed Generations (DGs) in distribution systems in Denmark. Even more DGs are expected to be installed in the coming years. With that, to utilize them in maintaining the security of power supply is of great concern for Danish utilities. During the emergency in the power system, some distribution networks may be intentionally separated from the main grid to avoid complete system collapse. If DGs in those networks could continuously run instead of immediately being shut down, the blackout could be avoided and the reliability of supply could be increased. However, when to island or how to ensure the islanded systems can survive the islanding transition is uncertain. This article proposes an Islanding Security Region (ISR) concept to provide security assessment of island operation. By comparing the system operating state with the ISR, the system operator can clearly know if it is suitable to conduct island operation at one specific moment. Besides, in order to improve the computation efficiency, the Artificial Neural Network (ANN) is applied for fast ISR formation. Thus, online application of ISR based islanding security assessment could be realized.     

骨间背侧动脉岛状皮瓣修复手背皮肤缺损25例临床观察

目的研究骨间背侧动脉岛状皮瓣修复手背皮肤缺损的手术方法和效果。方法采用将岛状皮瓣的血管蒂改良筋膜血管蒂修复手背皮肤缺损25例。结果 25例岛状皮瓣全部存活。随访8个月～4年,皮瓣色泽基本能够与邻近皮肤相同,局部平坦而且质地较软,手指与手掌功能正常,效果满意。结论应用改进后的骨间背侧动脉岛状皮瓣修复手背皮肤缺损,既不牺牲前臂主要血管,皮瓣成活率高,而且手术安全、简便,适宜广泛推广。     

An overview of instrumentation and control systems of a Korea standard nuclear power plant: A signal interface standpoint

This paper presents an overview of instrumentation and control (I&C) systems of a pressurized water reactor (PWR) type nuclear power plant (NPP) in Korea. Yonggwang unit 3, which was constructed as a basis model for a Korea standard nuclear power plant (KSNP), is selected as an example for the presentation. This overview is derived from analyzing the I&C systems based on a top-down approach. The I&C systems consist of 30 systems. The 183 I&C cabinets are also analyzed and mapped to the systems. The overview is focused on an interface between the systems and the cabinets. This information will be used to understand the implementation of the I&C systems and to group the systems for an upgrade.     

Recombinant Landscapes in the American City

How are urban actors, such as landscape designers, community groups, developers and local politicians, actively restructuring their environments to meet the challenges of the American city in the new global context? Grahame Shane outlines the approaches to landscape that have been emerging since the mid-20th century and are set to recombine urban assemblages whether they are located in historic city centres, postindustrial waterfronts or suburban sprawl.

东天山土屋斜长花岗斑岩的成因——来自围岩的证据

东天山土屋大型斑岩铜矿床的成因还存在较大争议。本文报道了斑岩铜矿的远矿围岩、近矿围岩和斜长花岗斑岩的主量元素、微量元素和Pb同位素地球化学特征。远矿围岩和近矿围岩具有相似的地球化学特征,属于岛孤火山岩。斑岩具有富铝、钠。富集轻稀土、亏损重稀土和高Sr／Y比值等特征。铅同位素都落在地幔演化线附近。对比研究表明,斜长花岗斑岩属于埃达克岩,为俯冲洋壳部分熔融的产物。
