建立AutoCAD与ArcSDE之间的桥梁--基于ArcSDE CAD Client的动态数据入库解决方案

随着GIS的发展和广泛应用，越来越多的单位选择了ESRI AreGIS的技术路线，开始采用AreSDE作为其数据管理平台．这些单位在更换数据管理平台时需要把现有数据迁移或转换到AreSDE中，同时应用系统需要进行部分的修改或在新平台下重新开发，然而很多设计部门仍然使用AutoCAD设计，他们在报建审批时提供的设计图形仍然是DWG／DXF格式的电子数据，为此需要解决AutoCAD和ArcSDE的数据动态交换问题．     

Information and communication technology (ICT) in secondary schools: the role of the computer coordinator

A study was conducted in 2002 to evaluate the use of information and communication technology (ICT) in 21 secondary schools in one region of New Zealand. As part of the study, the role of the ICT coordinator was investigated. All the ICT coordinators were surveyed and 14 of them were interviewed in‐depth. It is found that they were all well‐equipped to take up a significant leadership role in their schools and some of them have already demonstrated visible leadership. This paper also identifies some obstacles that have reduced their effective leadership in ICT use in their schools.     

在语文教育的路上,我们迷失了自己

韩军说,我们在语文教育的路上失落了太多的“根本”,于是他“呼唤中国语文教育返本归根”。在《中国教育报》组织的“在语文教育的路上我们失落了什么”的讨论中,有人认为,“我们失落了眼泪”;有人认为,我们失落了“语文基础知识”、“讲授式教学法”、“教学内容的科学性”等等。其实,细想来,最根本的是,在语文教育的路上,我们迷失了自己。一自清末“废科举,兴学校”以来,中国的教育一直在探索中艰难前进。就语文教育而言,教学内容从文言文转变为白话文;教学方法从注重评点串讲变为讲求师生互动;教育目的从以“传道”为主到以学习语言文字…

浅析中国内部审计存在的理论基础

通过对新制度经济学中交易费用理论、契约理论以及受托责任理论的研究分析，指出在中国现代企业制度的建设中引入内部审计部门的必要性，并进一步指出在当前经济改革和实践背景下，在对传统企业的改造中，建立内部审计是提高中国企业附加值，加强企业核心竞争力的有效途径。     

Effects of osmotic stress on antioxidant enzymes activities in leaf discs of P<Subscript>SAG12</Subscript>-<Emphasis Type="Italic">IPT</Emphasis> modified gerbera

Leaf senescence is often caused by water deficit and the chimeric gene PSA612-1PT is an auto-regulated gene delaying leaf senescence. Using in vitro leaf discs culture system, the changes of contents of chlorophylls, carotenoids, soluble protein and thiobarbituric acid reactive substance （TBARS） and antioxidant enzymes activities were investigated during leaf senescence of PSA612-1PT modified gerbera induced by osmotic stress compared with the control plant （wild type）. Leaf discs were incubated in 20%, 40% （w/v） polyethylene glycol （PEG） 6 000 nutrient solution for 20 h under continuous light [ 130 μmol/（m^2·s）]. The results showed that the contents of chlorophylls, carotenoids and soluble protein were decreased by osmotic stress with the decrease being more pronounced at 40% PEG, but that, at the same PEG concentration the decrease in the transgenic plants was significantly lower than that in the control plant. The activities of superoxide dismutase （SOD）, catalases （CAT）, ascorbate peroxidase （APX）, guaiacol peroxidase （GPX） and dehydroascorbate reductase （DHAR） were stimulated by PEG treatment. However, the increases were higher in PSA612-IPT transgenic plants than in the control plants, particularly at 40% PEG treatment. Lipid peroxidation （TBARS content） was increased by PEG treatment with the increase being much lower in transgenic plant than in the control plant. It could be concluded that the increases in the activities ofantioxidant enzymes including SOD, CAT, APX, GPX and DHAR were responsible for the delay of leaf senescence induced by osmotic stress.     

大型仪器设备网上预约系统的建立与实践

随着高校数字化校园系统的不断完善和对大型设备资源共享要求的不断提高,利用校园网络构建大型仪器设备共享平台已经成为许多高校设备管理部门的共识。应用信息化手段代替繁琐的人工操作,实现开放共享设备预约方式的网络化、智能化,能够使预约程序更加方便和快捷,确保设备的预约使用更加透明化、公正化,从而最大限度地发挥设备的使用效益。     

旋风除尘器操作试验台的建模设计

设计制作了"旋风除尘器操作试验台",该装置能调节风量、进灰量等各种试验参数,可观察除尘器内部的气流运动、除尘效果和灰分收集情况,为"大气污染控制工程"和"锅炉原理"等课程的教学提供了实验手段。通过对旋风除尘器的工作原理及结构进行分析,建立以除尘效率、压力损失为目标函数的双目标数学模型。考虑了设计变量和约束条件后,经过优化设计,寻找出旋风除尘器的最优化结构参数,绘制试验平台结构图,并制作了旋风除尘器操作试验台。     

日本加强教师教育实践取向的改革动向

通过对日本近年来所进行的教师教育制度及教育课程改革内容的研究,揭示其以实践取向为重心的改革特点。文章追寻战后日本的教师教育改革的轨迹,从教师教育理念的转变,教师资格标准的改革,尤其是教师培养的课程结构变化等几个侧面,分析日本在教师教育方面所进行的改革和存在的问题,解读改革的实践取向,为中国教师教育改革提供参考。
