    [中文文摘]用高速碰撞共沉淀法制备m(CuO) /m(ZnO) /m(Al2 O3 )比分别为 60 /3 0 /1 0和 3 0 /60 /1 0的 1 #和 2 #催化剂 ,结果表明高ZnO的 2 #催化剂活性较好 ,分散度较大。XPS测试表明 2 #催化剂表面ZnO吸附的中间体 (CHx 或CHxO)较多且表面的Cu+1浓度较高 ,从而促进CO加氢合成甲醇的活性。[英文文摘]Cu/ZnO/Al_2O_3 catalysts with ratios of 60/30/10 and 30/60/10 have been prepared by high speed collision coprecipitation method. The performance of the catalyst with the higher ZnO content shows the higher activity in methanol synthesis. The characterization results indicated that the catalyst with the higher ZnO content has higher dispersion. On the surface of the higher ZnO content catalyst, there was more Cu+1 and more intermediate (CH_x and CH_xO) adsorpted. It is beneficial for the CO hydrogenating to produce methanol

    乡土历来是被文学钟情而为美学忽略的场域,本文试从现实的乡土出发,以文学的乡土作参照,建构美学意义的乡土之维。乡土美学是工具理性背景下的怀旧美学,是大众传媒笼罩下的人本美学,是世俗文化遍布下的审美乡土,是消费都市充塞下的神性乡土。回到乡土的过程是一次审美历史地理学意义的返乡之途。本文共分四大部分。第一部分“乡土何为”将“乡土”这一语词同易于混淆的“故乡”、“民间”作出界阈区分,得出“乡土”涵义。第二部分“乡土美学何为”重在从价值论而非认识论的角度述说乡土美学的现状意义。此部分讨论了乡土美学的产生背景、乡土美学的审美范畴和乡土美学的非审美范畴。后两点是从审美主体入手,吸取张建永教授的“乡土美学是距...Native soil is used to being emphasized by literature, but being ignored by aesthetics. With the beginning of discussing the practical native soil , this paper attempts to set up the aesthetic dimension of native soil by consulting literature native soil. Native soil aesthetics is nostalgia aesthetics in the background of facility rationality , is Human- oriented aesthetics being involved by the ...学位:文学硕士院系专业:人文学院中文系_艺术学学号:20030105

    年轻的"艺术学"在中国取得"合法"地位仅十余年,目前对"艺术学"的专业建设与学科布局学界颇有争议,且在很多高校中尚未获得广泛认同。本文试图从三个方面阐述加强综合性大学"一般艺术学"建设的意义,说明"一般艺术学"有利于艺术术科的实践与理论的有机结合,有利于不同门类之间共性的发掘,有利于在当前大众文化背景下的艺术研究

    Purchasing Management in The Supply Chain Management Model --------- The Case of ABC Company

    随着科技的进步和经济的发展,全球化信息网络和全球化竞争市场渐渐形成,企业管理模式开始从“纵向一体化”向“横向一体化”转变,从而使企业与企业之间的竞争,转化为供应链和供应链之间的竞争。采购是供应链管理中一项极其重要的因素,因为买家—供应商关系以及供应商的能力决定着进货物料质量,送达时间,采购价格等因素。另外,采购作为大多数企业发生成本最大的领域,充分挖掘采购作为企业的第三利润源泉的作用,对于降低成本,提高企业的竞争地位有着重大的战略意义。 因此在此背景下研究供应链管理模式下的采购管理具有重要的现实意义。本文论述了供应链管理模式下的采购管理的特点,结合ABC公司采购管理的现状,在ABC公司进行一...During the technology innovation and economy development, globalized information network and competitive market is constructing.

    贵金属纳米颗粒的性质与其尺寸、组成和形貌(或表面结构)等因素密切相关。近年来科学家们在贵金属纳米颗粒尺寸和形貌的控制合成中进行大量研究,其方法多是改变反应条件或进行外延生长。而利用预先制备好的纳米颗粒进行二次形貌改造的研究鲜有报道。 此外,纳米颗粒尺寸、形貌的可控合成往往需要引入一定的表面稳定剂、保护剂或用于改变表面能的小分子。然而,这些表面保护、调控剂的引入,对纳米颗粒的性质,特别是一些与表面密切相关的性能(如催化),产生负面影响。本课题组的前期研究发现,在N,N-二甲基甲酰胺(DMF)还原乙酰丙酮钯[Pd(acac)2]合成Pd纳米颗粒的体系中,聚乙烯吡咯烷酮(PVP)和I-离子的共同引...It has been demonstrated that properties of noble metal nanoparticles highly depend on their sizes, composition, and shapes (or surface structures). Accordingly, the size- and shape-controlled synthesis of noble metal nanocrystals has attracted enormous attention in recent years.
