要地防空作战中空中目标威胁度估计的数学模型

为了准确有效地判断敌空中目标的威胁程度,运用层次-效用方法,对要地防空作战中空中目标威胁度建立数学模型。先用层次分析法建立影响因素诸指标的层次结构,然后导出指标因素的效用函数,对其加权和线性变换,得到目标威胁度。该模型使复杂的问题条理化,操作性强,便于计算机辅助决策,为防空指挥员对空情威胁做出正确判断提供了科学依据。     

生态润滑剂：可持续发展的必然选择

在介绍润滑剂对环境和健康危害的基础上阐明了发展生态润滑剂的重要性,指出改善矿物润滑剂生态效能、发展环境友好润滑剂是当前发展生态润滑剂的两个根本途径,必须加快矿物润滑剂的生态化进程,大力发展环境友好润滑剂,重视润滑剂的生态设计。     

面向新化学威胁形式的防护技术与装备

近年来,化学威胁的形式发生了变化,出现了类化学战、化学恐怖以及针对平民和环境的次生危害,给防化科研和防化工作提出了新的挑战。分析传统化学战与这三类新化学威胁形式的异同点发现,这些新威胁形式之间有着较多的共同点,而与传统化学战威胁形式则有较大差异。中国拥有为数众多的大型化工生产、储存设施,这些设施很可能成为袭击的目标,因此必须转变化学防护观念,尽快研究防化新技术、新装备,建立国家动员机制。     

基于效能分析的坦克主动防护系统建模研究

主动防护系统是坦克防护体系的重要组成部分,建立坦克主动防护系统模型对提高作战仿真的可信性,尤其是对提高涉及坦克作战的作战仿真可信性具有重要意义。创新提出了基于可用性、可靠性和能力的系统使用周期(System Use Cycle,SUC)建模方法,并重点对坦克主动防护系统的侦察探测能力、信息处理与控制能力以及拦截能力进行了建模。最后,将坦克主动防护系统模型应用到作战仿真系统中,以俄罗斯"竞技场"主动防护系统为例,研究了主动防护系统对坦克战场生存能力的影响。仿真实验结果表明:主动防护系统能有效提高坦克的战场生存能力。     

“What is dear to you?” Survey of beliefs regarding protection of critical infrastructure against terrorism

Up to the present, there is only very little research on how the population perceives terrorism and its threats, even though support from the population is crucial for effective counterterrorism. By eliciting beliefs and subjecting them to content analyses, six factors were found that determine the protection worthiness of a target in the people's view: the potential damage to “people,” “symbolism,” “economy,” “politics,” “nature,” and “image/publicity.” These empirically found factors are in line with factors specified by terrorist target selection models. They differ in the strength of their cognitive representation among participants and, thus, their subjective importance to the people. The first three factors are shared among all participants, whereas the latter ones could only be found in a part of the participant sample. People's judgments of the targets' protection worthiness differ substantially from their judgments of the targets' attractiveness to terrorists, even though the same factors seem to be involved. This study offers an insight into the people's mental model about protection worthiness of targets. Together with classical risk analysis and knowledge about terrorists, these results can form a basis for setting up a holistic scheme for critical infrastructure protection.     

Nuclear security culture enhancement: the role of culture coordinators at Russian nuclear sites

In 2002, a Nuclear Security Culture (NSC) Enhancement Program with the mission to raise the level of the NSC at sites and facilities in Russia's nuclear complex was launched under the guidance of the Russian State Corporation “ROSATOM” and with support from the US Department of Energy. A Joint Working Group for NSC with both Russian Federation and US members was formed and charged with the design and implementation of the program. The program was implemented at sites and facilities on a pilot basis. Nine sites participated in the Pilot Project. The key program component was an establishment of Culture Coordinators (CCs) with the authority to coordinate and implement NSC enhancement activities at sites and facilities. The CCs have served as the force that has maintained the momentum of the Pilot Project and continuously steered the site NSC enhancement efforts. The contribution of the CCs in achieving the positive outcomes of the program cannot be overstated.     

新疆塔吉克族非物质文化遗产保护研究

塔吉克族是新疆的世居民族之一,新疆塔吉克族的国家级、自治区级和地区级非物质文化遗产项目类型丰富,具有民族性、地域性、综合性和独特性的特征。塔什库尔干塔吉克自治县在塔吉克族非物质文化遗产保护方面,采取了多种措施,取得了丰硕的成果,但是依然存在着一系列的问题。本文力求通过加强塔吉克族非物质文化遗产的挖掘、整理和申报、加大对国家级和自治区级的非物质文化遗产的保护、在合理保护的前提下加大非物质文化遗产的产品化进程、建设文化生态保护区等措施,探讨新疆塔吉克族非物质文化遗产保护的基本思路。     

南沙珊瑚礁生态系统的调查与保护对策

2009年12月30日-2010年1月10日,采取线路调查和咨询调查相结合的方法,调查了南沙渚碧礁、永署礁、华阳礁、赤瓜礁与美济礁珊瑚的分布、生长发育及生物多样性变化情况.发现南沙珊瑚礁生态系统受到的破坏干扰强烈,珊瑚白化现象突出,生物多样性显著下降,珊瑚礁生态系统退化态势严峻.为保障南沙珊瑚礁生态系统的健康发展和可持...     

涉外非战争军事行动的法律保障问题研究

近年来,随着军队使命任务的拓展,涉外非战争军事行动日益成为国家运用军事力量的重要方式。因此,必须加强涉外非战争军事行动中法律保障问题研究,使其在法律框架下进行。加强对涉外非战争军事行动的法律保障,有助于为军队遂行多样化军事任务提供有力的法律支持和保障。     

古建筑防火新技术研究

阐述了古建筑火灾的危险性,并从本质安全的角度研究了古建筑中木材、纤维织物的阻燃措施。指出木材的阻燃处理方法通常采用物理和化学方法,而化学方法可采用表面涂覆、浸渍处理、化学改性三种方法;纤维织物阻燃处理采用共聚阻燃改性、共混阻燃改性、阻燃后整理、接枝共聚、皮芯型复合纺丝等方法。可以根据具体情况选用合适的阻燃处理方法,从而达到降低材料可燃性的目的,大大提高古建筑的火灾风险等级。
