Nitrogen contamination of surface water is a worldwide environmental problem with intensive agricul- ture and high population densities. We assessed the spatial and seasonal variation in concentrations of total nitrogen and different nitrogen species present in surface-water in Beijing, China. Also, chemical （NO3-N/C1-） and isotopic （615Nnitrate） indicators were used to identify nitrate sources. The results showed that, during 2009 and 2010, nitrate nitrogen concentrations ranged from 0.7 to 7.6 mg· L^-1, ammonium nitrogen from 0. I to 3.4 mg· L^-1, and total nitrogen from 2.4 to 17.0mg· L^-1. Inorganic nitrogen accounted for between 60 and 100% of total nitrogen at the ten monitoring sites. Nitrate nitrogen, ammonium nitrogen, and total nitrogen concentrations at the 2 downstream monitoring sites in south-eastern Beijing were significantly higher than those at the other eight upstream monitoring sites （P 〈 0.01）. Examination of seasonal variation showed that there was a significant inverse relationship between nitrate nitrogen concentrations and precipitation, and that nitrate nitrogen concentrations peaked in the dry seasons. The information given by the 15Nnitrate values and nitrate nitrogen concentrations, combined with the NO3-N/C1- ratio distribution, showed that domestic sewage was the major source of nitrate in Beijing. Methods to control and reduce sewage pollution are urgently needed to help manage surface water quality in Beijing.

巴西东南部坎普斯盆地的巴拉库达（Barracuda）和龙卡多尔（Roncador）特大油田属于1990-1999年间全世界最重要的油气发现，储层为硅质碎屑浊积岩，储量估计有40×10^8桶油当量。这两个油田分别位于深水区和超深水区，水深范围600-2100m。巴拉库达油田发现于1989年4月，发现井为4-RJS-381井，水深980m。油田面积约157km^2，水深范围600-1200m，储层为第三系浊积岩，地震属性分析表明：古新统、始新统和渐新统含油砂岩包裹在页岩和泥灰岩中，油藏以地层圈闭为主。油田地质储量为27×10^8桶，总可采储量分别为：渐新统油藏6．59×10^8桶，始新统油藏5．80×10^8桶。巴拉库达油田与卡拉廷加（Caratinga）油田因地理位置接近而予以共同开发。开发方案结合了试验生产系统（2002年10月停止运转）和永久性生产系统（安装实施中）的使用。试验生产系统于1997年投产，采用浮式采油、储存和卸油（简称FPSO）固定开采装置，永久性生产系统则预计于2004年的下半年投产，整个开采系统包括20口采油井和14口注水井。原油和天然气的装卸和处理均由处理能力为15×10^4桶／日和480×10^4In^2／d天然气的FP—S0装置进行。2006年将达到峰值产量。龙卡多尔油田发现于1996年，发现井为1-RJS-436A，水深为1500-2100In，油田油气储量巨大（地质储量92×10^8桶，总可采储量为26×10^8桶油当量），储层为上白垩统（麦斯特里希特阶）浊积砂岩。该油田发现井数据证实：总有效厚度为153m的麦斯特里希特阶油藏被页岩夹层分割成5个主要的层位，仅有最上层可见地震振幅异常，其余4层与页岩夹层有明显区别的声阻抗，因而未见振幅异常。油藏的评估表明原油油质不一（18°～31．5°API）、油藏结构复杂，其外部几何形状为东部和北部下倾、西部和南部尖灭，圈闭为构造一地层复合圈闭。油田被一些大型主要断层切割成三个主要断块：西南上升断块、北部上升断块和东南下降断块。由于龙卡多尔油田的面积和储量规模都较大，因而将分4个开发单元投入开发。预计2011年将达到峰值，产量50×10^4桶／日。开发单元Ⅰ期将开发油田的东部和北部区块，部署21口水下采油井和7口注水井。开发单元Ⅱ期将开发西部稠油区块，计划安装2套生产装置（深吃水沉箱船[SPAR]和FPSO），预计2年后31口采油井的产量将达到峰值18×10^4桶／日。

本文研究了湿热荷载作用下自适应夹芯板在黏弹性介质中的振动.简单支撑的夹芯板包含三种类型的层:纤维增强层、两个磁致伸缩致动器和黏弹性面.结构的顶部和底部建模为Kelvin-Voigt黏弹性模型.基于板理论,主要振动模式应用汉密尔顿原理.数值算例研究了各种参数对湿热振动特性的影响,如厚度比、长径比、黏弹性与磁致伸缩层厚度比、模态、黏弹性基体刚度和阻尼系数、层压方案、反馈系数大小、磁致伸缩层位置、黏弹性结构阻尼、温升和水分浓度的程度.研究结果表明温度和湿度浓度是影响振动的主要因素.对于在湿热荷载作用下板的设计,上述研究结果有助于智能结构的开发与应用并控制其在这种环境条件下的振动.
