    二甲基硫(Dimethylsulphide,DMS)是一种重要的海洋生源硫化物,通过海气交换进入大气后生成生物源硫酸盐气溶胶从而对气候产生影响。海洋大气中约90%的DMS是来自海洋,南大洋占世界大洋面积的20%,是全球DMS重要的源之一。南极及南大洋在全球气候系统中扮演着重要的角色,是天然硫化物循环研究的重要场所。目前,对南极区域硫循环的研究,已经逐渐形成了从海水、大气到海冰的立体观测体系。然而,由于南极地区气候恶劣,在此开展硫循环的研究异常困难,能获取现场观测数据也十分稀少。因此,在中国南极科学考察中开展硫循环的研究,对了解南极硫循环及其对气候的影响具有重要意义。 本研究首次分析了从200...Dimethylsulphide (DMS) is an important marine biogenic gas, which can form marine sulfate aerosols when released across the sea-air interface. These aerosols would impact the global climate finally. About 90 % DMS in the atmosphere comes from the ocean. The southern ocean, which consists about 20 % of the whole ocean area, is one of the largest atmosphere DMS sources. The Antarctica and Southern o...学位:理学博士院系专业:海洋与地球学院_海洋化学学号:2232012015344

    国际投资领域历来是腐败的高发区,即使时至今日,国际投资腐败问题仍然非常严重。而投资腐败已成为国际投资仲裁庭在案件审理中需要考虑的一项内容,国际投资腐败行为在国际投资法上的产生的法律后果也越来越受到人们的重视。 投资腐败的法律后果主要体现在两类案件中。第一类是东道国官员受贿或索贿,并根据受贿或索贿的结果来进行决策,从而侵害了未支付贿赂的投资者的合法权益,因此投资者向仲裁庭提起仲裁的案件。仲裁庭一般认定这种对投资者的不公正对待违反了东道国的投资者保护义务,秉持了较为正确的裁判导向。而第二类案件则不同,在该类案件中,东道国以投资设立、获得过程中存在腐败行为为由对投资者提出的仲裁请求主张管辖权抗辩或...International investment has always been high incidence of corruption.

    当前,我国现代物流在功能和发展潜力上的主要问题在于现代物流系统的不完善以及物流运作过程的不合理。自然形成的物流系统由于缺乏前瞻性和系统规划,在物流资源的配置,物流网络的结构等方面,很难保证其可靠性、合理性,协调性和最优化;而物流运作过程,主要是运输过程和仓储过程,仍以经验管理为主,基本上没有采用优化理论和方法,不合理现象随处可见,难以产生“第三利润”。 计算机仿真技术是目前比较先进的物流系统研究方法,它的一个最大的优点是,不需实际安装设备,不需实际实施方案即可验证设备的导入效果和比较各种方案的优劣。在工程建设或作业流程的计划阶段发现和解决问题,因此,它对降低整个物流投资成本起到不可缺少的作用...At present, China's modern logistics development potential on the features and the main problem is that the imperfections of modern logistics systems and the tommyrot logistics processes.

    2004年6月26日,十国集团的央行行长和银行监管当局负责人一致通过了《资本计量和资本标准的国际协议:修订框架》,即《新巴塞尔资本协议》,并决定于2006年底在十国集团开始实施。新资本协议标志着国际银行风险监管正由监管资本时期逐步进入经济资本时期。本文认为以推进经济资本监管为主要特色的新巴塞尔资本协议在我国实施的条件还不成熟。但是,我们应以新巴塞尔协议为目标,在某些有可能率先突破的领域,例如银行资本充足率管理、信息披露制度、内部评级制度和外部评级制度等,找出现实问题然后积极创造条件予以解决,以各个突破的方式,从量变逐步实现质变,争取早日达到新资本协议的实施要求。June 26 , 2004, central bank governors and the heads of bank supervisory authorities in the Group of Ten (G10) countries issued a prss release and endorsed the publication of International Convergense of Capital Measurement and Capital Standards:a Revised Framework, the new capital adequacy framework commonly known as Basel II.The New Basel Capital Accord indicate international bank risk managemen...学位:经济学硕士院系专业:经济学院财政金融系_金融学(含保险学)学号:20011206

    包袋行业使用ERP已经不是一件新鲜的事情了,随着越来越多的企业加入ERP阵营各种各样的问题也出现了。首先,在我国包袋行业一般规模都比较小生产能力和销售额度并不算高,这就决定了这些企业不会花非常高的费用去部署一个ERP产品,传统ERP虽说功能是比较强大,但这些功能对于中小包袋企业并不适用,也就是说这些企业往往会花大量的冤枉钱去购买一些并不符合自己企业特性的产品,这就是现在许多包袋行业抱怨ERP系统的一个原因。如何减少ERP部署费用和维护费用,如何使ERP产品敏捷化和实用化是本次工作的重点。其次,企业的业务发生变化这种可能性是有的,但是ERP产品的业务逻辑是固定的,怎么样使ERP产品自由定制就成了...Bag industry has been using the ERP is not a new thing, as more and more enterprises to join the ERP camp wide range of issues have emerged.
