基于SSM分折的科研评价系统探讨   总被引：2，自引：0，他引：2  

孟溦  John Mingers  刘文斌 《科研管理》2007,28(2)

科技评价体系是一个复杂的,多目标评价体系。当今科技评价已逐渐从强调科研产出,转向同时关注资源的使用效率,注重科技创新能力的提升和对国民经济发展的贡献。如何建立一个客观、公正、健全、规范的,且具备可操作性的科学评价体系引起了政府和科技界的广泛关注。本文以SSM系统分析为基础,从3E出发探讨了评价指标体系的构建和评价系统的设计。基于系统分析基础上形成的指标体系,既考虑了直接的产出,又分析了内部运行机制,形成的指标体系相对更全面、完整,在此基础上针对具体评价内容选择适宜的评价方法,可定量或定性,软硬结合,具有透明性和延展性,同时易与决策管理部门交流。  相似文献

Left-handed materials in magnetized metallic magnetic thin films     

伍瑞新  XIAO  John  Q. 《浙江大学学报(A卷英文版)》2006,7(1):71-75

INTRODUCTION Veselago (1968) showed that if both the permit- tivity ε and the magnetic permeability μ of a material are negative, the propagation direction of an elec- tromagnetic (EM) wave will be opposite to its energy flow direction. Such media are called left-handed materials (LHMs) since the electric field E, magnetic field H, and wave vector k in these media form a left-hand triplet of vectors, instead of a right-hand triplet observed in conventional materials.

Development of Shallow Footing Anti-Ram Bollard System Through Modeling and Testing   总被引：1，自引：0，他引：1  

CRAWFORD John E 《天津大学学报(英文版)》2006,12(Z1)

In past terrorist attacks, vehicle borne improvised explosive devices (VBIED) have been the primary manner of attacking buildings and infrastructures. Preventing unauthorized vehicles from approaching a protected area with anti-ram systems would maintain an established standoff distance against moving and stationary vehicles and consequently reduce blast and debris threats. This strategy has been considered the first line of defence against terrorists. Several types of anti-ram devices have been developed in accordance with U. S. Department of State K-rating criteria, for example, wedge barriers, rising beams, sliding/swing gates, and drop arms. However, these devices typically need a deep foundation for installation and can't be implemented into many locations where a depth of excavation is limited in order to protect utility lines of buildings and infrastructures. This paper presents a recent development of a series of shallow footing anti-ram bollard systems (SFABS) that can satisfy K-12 rating with only five-inch thick footing. A high-fidelity physics based finite element technique with a vehicle crash model is used for predicting anti-ram capacity and determining design parameters of the SFABS. Full-scale vehicle crash tests of the developed SFABS systems have been carried out to validate the design and analysis.  相似文献   

世界新七大奇迹     

John Ward Anderson  yoyo 《英语辅导》2007,(7)

正如当年法国人顾拜旦复兴奥林匹克运动会一样,瑞士人伯纳德·韦伯以自己的执著,将"世界七大奇迹"这一颇具古希腊色彩的概念成功复活。2000年,他创建了"世界新七大奇迹基金会"。7年间这个基金会在全球范围内发起了一场大评选活动。到目前为止,该机构已经从世界各地提供的77个候选名单中评出了21个最后的入围者。中国的长城也进入"世界新七大奇迹"决赛,成为候选热门。评选的最终结果将于2007年7月7日在葡萄牙首都里斯本揭晓。读者们,当你手捧CR还未错过投票截止日期时,不妨马上登录www.new7wonders.com中国的长城般上宝贵的一票吧。即使已经知道结果了,那也没关系。正如伯纳德·韦伯所说,这个评选的最终目的和宗旨是呼吁人们重视保护世界名胜古迹,防止重蹈"古代七大奇迹"因保护不力而消失的覆辙。  相似文献   

Numerical Calculation of Concrete Slab Response to Blast Loading     

KUZNETSOV Valerian A  WASCHL John 《天津大学学报(英文版)》2006,12(Z1)

In the present paper, a dynamic plastic damage model for concrete has been employed to estimate responses of a reinforced concrete slab subjected to blast loading. The interaction between the blast wave and the concrete slab is considered in 3D simulation. In the first stage, the initial detonation and blast wave propagation is modelled in 2D simulation before the blast wave reaches the concrete slab, then the results obtained from 2D calculation are remapped to a 3D model. The calculated blast load is compared with that obtained from TM5-1300. Numerical results of the concrete slab response are compared with the explosive test carried out- in the Weapons System Division, Defence Science and Technology Organisation, Department of Defence, Australia.  相似文献

Development of Light Weight Structures to Provide Blast-Resistant Designs     

CRAWFORD John E 《天津大学学报(英文版)》2006,12(Z1)

In the past, blast-resistant designs for structures were often constructed with massive type structural systems, which relied more on brute strength than on finesse to achieve the required blast resistance. However, structures composed of COLD-FORMED steel components, such as sheet metal and metal studs, have shown great promise in providing blast resistance with the added benefits of low cost and ease of construction. Some examples of using such structures to provide containment for package handling facilities (PHF) are described in the paper for situations where blast containment is needed, such as a potential package bomb being discovered during the package vetting process. Results from tests and analytic data are used to illustrate aspects of design peculiar to such types of applications. Designs for specific capacities of PHF are described.  相似文献

离别辞:节哀     

John Donne  曹军 《海外英语》2002,(12)

As virtuous men pass mildly away, And whisper to their souls to go, Whilst some of their sad friends do say, "Now his breath goes, " and some say, "No. "So let us melt, and make no noise No tear-floods, nor sigh-tempests move, T were profanation of our joys To tell the laity our love.Moving of th' earth brings harms and fears ; Men reckon what it did, and meant ; But trepidation of the spheres, Though greater far, is innocent.  相似文献
