A Case Study on LY Oil Depot Relocation

在国内成品油市场对外资开放之后，我国成品油市场逐渐与国际接轨，成品油市场竞争愈来愈激烈。油库作为成品油销售系统中关键的一个环节，油库选址直接关系到企业成本、服务水平以及后续运营策略的制定，是成品油销售企业发展中越来越重要的部分。油库的选址由于成品油的危化品特性而比一般仓库选址更加严苛，选址时所要考虑的因素更加复杂。随着国内油库建设的不断加快，如何对油库建设进行科学、合理、规范的选址，已经成为我国油库建设的重要问题。LY油库建于上个世纪50年代，原处于城郊，随着城市的发展，已经被包围于城市中心，出于安全以及企业未来发展规划考虑，油库迫切需要迁往其它地区。 本文从国内外的文献及研究成果中总结了将...After the domestic product oil market opening to the foreign investment, Chinese product oil market is gradually in line with international standards, product oil market competition becomes more and more fierce.

Study on Improved MAC protocols of VoWLAN system

随着无线通信技术和移动终端技术的迅猛发展，以IEEE802.11为基础的无线局域网（WLAN）得到了越来越广泛的应用。与此同时，VoIP以其价格低廉、资源利用率高等优点成为当今发展最快的网络应用之一。在这两种技术的推动下，VoWLAN（VoiceoverWLAN）逐渐兴起。现在IEEE802.11b已成为WLAN的事实标准，而WLAN又有传输语音业务的需求，然而IEEE802.11b使用竞争信道，主要支持非实时的数据业务，不能满足对时延和时延抖动敏感的语音业务的QoS保证。因此，研究IEEE802.11bWLAN接入环境下的语音传输质量保证方案，具有重要的应用推广意义。本论文就是在这样的背景下...With the rapid development of wireless communications technology and mobile terminal technology, the wireless local area network (WLAN) based on IEEE 802.11 is finding more and more applications.

浅谈VDSL(Very High Bit Rate Digital Subscriber Line)

XDSL宽带接入的典型是ADSL和VDSL。本文首先简要介绍VDSL技术及其标准化,然后比较ADSL和VDSL在速率、成本、传输质量和业务等方面的性能,VDSL有其明显的优势。但是实际上,没有任何一种接入技术能够解决所有的问题,它都有其适用范围,所以ADSL与VDSL最终将走向融合,采用DMT调制技术的VDSL2实现与ADSL2+的后向兼容将是VDSL发展的方向

传播的艺术:中美比喻说服的逻辑间距

比喻是传播中广泛使用的一种艺术.比喻中本体和喻体之间的关系体现了中美文化不同的思维方式.相对而言,中国比喻典型为直觉推理,美国比喻典型为形式逻辑.对中关大学生施测的结果,对两种比喻类型,整体思维高的中国大学生更易理解直觉推理比喻;分析思维高的美国大学生更易理解形式逻辑比喻.对中国大学生的思维方式启动实验表明,思维方式可以通过相关材料启动,并可以影响到广告中比喻的说服效果.启动整体思维的材料尚需进一步的研究.国家自然科学基金项目“东西方不同文化思维方式对广告说服的影响”(项目(71372076)的研究成果

Internal Marketing: A New Humanism-Orientation Perspective for Human Resource Management

通过回顾内部营销自1981年提出至今的相关文献,发现内部营销的研究存在三种不同的视野:即市场营销流派、人力资源管理流派和一般管理流派。立足于这三大流派的交集:“员工就是顾客”这一基准点,笔者认为“员工就是顾客”在本质上是一种以人为本的人力资源管理新视野,并在此基础上阐述了以人为本的人力资源管理新视野与传统人力资源管理视野之间的区别。Based on the review of the literature of internal marketing since Berry(1981) proposed,the author argues that different scholars mean differently when they discuss internal marketing,which can be classified marketing school,human resource school and general management school.Then,based on the cornerstone,"The employee as customer",the author suggests the nature of internal marketing is a new humanism-orientation perspective for HRM.Finally,the author compares the traditional perspective for HRM with this new perspective

Photocatalytic Degradation of Phenol by Self-organized Titanium Dioxide Nanotube Arrays

采用电化学阳极氧化法在钛基体上制得了高度致密的、有序的、均匀的TiO2纳米管阵列。用SEM、XRD等对其表面形貌和结构晶型进行了表征和分析。以TiO2纳米管阵列为光催化剂对废水中典型的有机污染物——苯酚进行了光催化降解,考察了影响光催化降解速率的因素。结果表明,在紫外光照下,苯酚水溶液的pH=3、ρ(苯酚)=10.0 mg/L时,具有锐钛矿相结构的TiO2纳米管阵列的光催化效果最好,相同条件下与溶胶凝胶法制备的纳米TiO2颗粒膜的光催化降解速率进行对比,前者比后者提高了近一倍。High-density,well-ordered and uniform titanium oxide nanotube arrays were prepared by electrochemical anodic oxidation.The morphology and crystal structure of the TiO2 nanotubes were characterized and analyzed by SEM and XRD.As a photocatalyst,TiO2 nanotube arrays were used to degrade phenol which is a typical organic pollutant in wastewater.The photocatalytic degradation under UV irradiation is most effective with anatase TiO2 nanotube arrays when pH of phenol solution is 3 and mass concentration of phenol is 10.0 mg/L.Compared with TiO2 nanoparticle coatings prepared by sol-gel process,the photocatalytic degradation rate of TiO2 nanotube arrays is almost doubled under the same experimental condition.国家自然科学基金项目(50571085
