Comparasion study on the effects of mangrove wetland sediments on the sequestration of typical sulfonamides from the estuarine water

作为陆地污染物进入海洋的屏障，红树林已然成为众多典型污染物汇聚的场所之一。近年来，海产养殖业的大肆兴起更是加重了抗生素在红树林区的直接污染。锁定态是控制土壤抗生素归宿的主要因素，具有环境存在时间长，危害大等特点，可通过再释放重回到环境中，对环境造成长期危害。对典型磺胺类在红树林群落沉积物中锁定能力的研究对于探索抗生素在红树林区的环境行为和红树林湿地抗生素污染控制及修复功能评估具有现实意义。本文选取了12种水产、禽畜及人用较为频繁的典型磺胺类药物，分别为磺胺甲噻二唑(sulfamethizole,SMT)、磺胺二甲基异嘧啶(sulfaisodimidine,SIM)、磺胺噻唑(sulfathia...Mangroves had been the pools of pollutants from land, for the functions of marine protective screen. Nowadays, with the aquaculture developing soon, mangroves were directly polluted by the aquaculture wastewater around them. Sequestration is the main control factor for the fate of antibiotics in soil, and have the characters of long-term exist and more harm, can be released into soil causing heavi...学位：工学硕士院系专业：环境与生态学院_环境工程学号：3312012115163

响 Impact on the apoptosis, invasion, proliferation ET-1 interfere with the formation of lung cancer

摘要 目的: 肺癌是最常见的恶性肿瘤之一,威胁着全世界人民生命和健康。同时它也是世界上发病率和死亡率增长最快的疾病之一。而且大多数肺癌患者到晚期才被诊断发现，在现阶段肺癌的治疗中，它仍然是无法治愈的。Endothelin(ET),由内皮细胞合成，是一种生物活性肽,是一种强烈的血管收缩剂，具有很强的收缩血管作用,随着对内皮素研究的不断深入，人们发现内皮素与肿瘤关系密切，对肿瘤细胞的生长、增殖、转移、凋亡及化学耐药等都方面都有影响。ET能够产生细胞生长因子可以促进肿瘤DNA合成,基因表达和肿瘤细胞增殖。ET有21种氨基酸组成,有研究发现,内皮素家族有四个同分异构体亚型包括ET-1ET-2ET-...Abstract Lung cancer is one of the most common malignant tumor, which is threatening the people's life and health around the world.

Economy Level of the Chinese Translated Text: Towards a Quantitative Descriptive Model

如何衡量译文的语言表达水平，这个问题是否需要理论化？是否能够理论化？本文要探究的，就是这两个紧密相关的、在翻译研究界尚未得到系统和深入回答的问题。这里把译文的语言表达水平，即译者译语能力在译文中的具体体现，称之为“译语效能”。译语效能的研究基本都是在悬置译文—原文关系的情况下进行的，它包括连贯性、美感和经济性三个维度，可以通过相应的三个变量，即连贯性水平、美感水平和经济性水平，来描写。这些工作难以一蹴而就，因此本文将在建立译语效能基本框架的基础上，把研究重心放在其中的经济性维度及与其相应的经济性水平变量上，构建语篇经济性和译文语篇经济性的理论框架，并以此为根据，提出汉语译文语篇经济性水平的量化...Whether it is necessary and possible to develop a theory on the evaluation of the language level of a target text remains a question to be further and more systematically answered in Translation Studies.

Electric Hot Assisted Turning and Its Process Monitoring

近年来，机械加工行业中出现了大量耐高温、强度高、硬度大的难加工材料。在这些材料的加工过程中，普遍存在着切削力大、刀具磨损严重、表面质量差等问题。用常规的刀具材料和加工方法很难进行切削加工，也达不到现代工业技术的要求。随着历史的发展，人们提出了许多针对这些难加工材料的加工思路和方法，加热切削就是比较好的思路，而导电加热切削则是其中一种行之有效的方法。 本文对现有导电加热切削技术做出了一些研究，提出了通电加热辅助车削的方法，意在探寻这种方法的可行性和效果。通电加热辅助车削是把低压大电流通入到由电源、加热电极和工件材料构成的回路中，利用电流流经电极—工件间接触电阻时产生的热量，使工件迅速升温从而软...Recently, lots of high temperature resistance, high strength and high hardness materials has appeared in machining industries.

Design and Implementation of Police Intelligence Warning Management System Based on J2EE

经济的发展和社会的进步，不仅给我们的生活带来了前所未有的变革，同时带来的还有违法犯罪行为呈现出智能化、隐蔽性、高发性等诸多特点。目前，对公安警情管理仍然采取以计算机为媒介，简单的利用电脑存储、传输的旧式警务工作模式。这模式早已无法适应新时期警务工作的需要，亟需开发一套新的警情预警管理系统。 针对这种现状，本文开发设计了一套基于J2EE的公安警情预警管理系统，能够实现警务相关警情的管理、分析、查询和警情预警等多功能一体的警情管理平台，为基层警务工作提供技术支撑。本论文首先介绍了目前国内外公安警情预警管理系统，在调研相关软件技术和警情信息管理的主要业务流程基础上，采用UML、J2EE技术和SQL...With the development economic and society, our life has changed unprecedentdely, but caused the many features eg.intelligentization, elusion, high incidence in criminals and illegals at the same time.

关于大连借重渤海大通道创建世界海洋城市总部的战略推进构想

在世界近现代史上,大连经历了在旧中国由于长期沦为殖民地而被动国际化和新中国建设时期特别是改革开放以后而主动国际化的特殊历史进程,使之在国内外均具有很高的城市知名度,所以不仅被邓小平认定为“东北之窗”,被江泽民题词为“北方明珠”,被朱镕基希望为“世界城”,而且由党中央首次单独向一座城市投放了国家战略,明确要求大连建设为东北亚重要国际航运中心,目前正在逐渐地步入现代化国际名城的理想境界。而在这一进程中,恰逢从山东半岛到辽东半岛的渤海跨海大通道也在论证与启动之际,有望作为重大战略工程纳入国家“十三五”规划,所以大连应当借重这一渤海蓝色新干线,积极跟进时代潮流,勇于承担国家使命,领衔创建与运作世界海洋城市总部,面向世界和未来整合全球海洋城市关系资源,把占世界经济总量72% 海洋城市(包括沿海城市与海岛城市)所拉动的海域经济带联系起来,为国家全面经略海洋、建设海洋强国和21 世纪海上丝绸之路提供战略支点,以利于中国在国际海洋领域提高话语权和决策权

Development of the facility for model scramjet testing

A hypersonic propulsion test facility has been constructed in IMCAS (Institute of Mechanics, Chinese Academy of Sciences) in order to provide a high enthalpy hypersonic flow for a model scramjet testing. The vitiated air is produced by a hydrogen/air and oxygen replenishment combustion heater with flow rate of 3.5kg/s, total pressure of 5MPa and total temperature of 2000K in maximum, and accelerated up to Mach 5.6 by a two-dimensional nozzle. Test chamber of the facility is evacuated by a one-stage central air ejector. The preliminary facility performance tests showed that the vitiated air heater could provide the high enthalpy flow as expected. A copper model scramjet without cooling is ready for testing. © 2001 The American Institute of Aeronautics and Astronautics Inc. All rights reserved
