    2001年的“9•11”事件后,美国政府采取了大幅降息等刺激经济的调控措施,美元信贷成本极其低廉。大量金融资本利用金融杠杆不断投机,制造了房地产市场泡沫,金融衍生品市场也随之膨胀。根据美国财政部对美国次贷担保债务凭证(CDO)市场的统计:2005年CDO市场总值为1510亿美元,2006年为3100亿美元,2007年仅第一季度就达2000亿美元。 -王静,《美国金融危机的根源及教训》,《文汇报》,2008年9月25日学位:工商管理硕士院系专业:管理学院高级经理教育中心(EMBA项目)_高级管理人员工商管理硕士(EMBA)学号:X200615614

    随着能源危机和环境污染的加剧,清洁绿色、可再生的太阳能电池发电受到广泛的关注。目前,由于太阳能电池成本较高、效率较低等因素的制约,难以进行大规模的应用。纳米材料由于具有比表面积大、晶体质量好等优点,用于太阳能电池,可以增加有效结面积、增加光的吸收和降低非辐射复合,从而提高太阳能电池的光电转换效率。同时,ZnO和II-VI族材料结合可在界面处形成II型异质结,调节有效带隙至可见光区域,使其具有在光伏器件应用的潜力。基于此构想,本文制备了ZnO纳米线和ZnO/ZnSe量子同轴线,研究它们的生长条件、晶体结构、光学、电学等特性,并制备了II型异质结的ZnO/ZnSe量子同轴线太阳能电池,取得了以下几...Solar cells have been a subject of great interest due to the growing awareness of energy shortage and environmental protection. Nevertheless, most of them suffer from either high cost or relatively low energy conversion efficiency. The use of nanostructured materials, especially nanowires is deemed as one of the promising approaches to overcome these issues. Nanowire arrays, compared with the bulk...学位:理学硕士院系专业:物理与机电工程学院物理学系_凝聚态物理学号:1982008115300

    任何一种管理思想和理论的提出都是以一定的人性假设为前提的。学习型组织理论的人性观包含了三个要点:学习人、创造人、团队人。这三者各有其内含同时又是相互联系,融为一体的。Any management thoughts or theory should be based on certain hypothesis of humanity. In the theory of learning organization, humanity features as learning man, creative man and team man, of which each has its own meaning and is integrated with the others
