现代海战中国外“矛”与“盾”武器的博弈

反舰导弹（矛）与舰载反导武器（盾）之间的斗争是现代海战重要格局之一。美俄二大军事大国在矛与盾的发展上,均以对方为假想敌,研究使自己的矛如何突防对方的盾,以及自己的盾如何拦击对方的矛。由于历史条件,国家政治需要和本国的技术优势不同,二国发展矛与盾的指导思想和设计准则,以及在攻防策略上都有很大不同。文章从深层次分析这些不同特点,并探讨它们的发展走向。     

电渗透防水防潮技术的工程应用

地下工程防水防潮一直是工程界的难题,传统技术存在难根治、易反复的缺点。选择某一洞库进行电渗透技术工程试点研究:先详细介绍电渗透技术和施工工艺情况;再采用在工程内布置电极并施加脉冲电压的方法,利用电场力迫使水分向工程外岩体移动,达到降低工程内部湿度、防水防潮的目的。工程应用表明,电渗透防水防潮技术拥有效果明显、运行费用低等突出优点,具有推广前景。     

Transnational terrorism as a spillover of domestic disputes in other countries

This paper models transnational terrorism as a three‐way strategic interaction involving a government that faces armed opposition at home, which may spill over in the form of acts of terrorism by the state's opponents against the government's external sponsor. The external sponsor also utilises deterrence against potential terrorists, which only lowers terrorism if terrorists are not intrinsically motivated by a deep‐seated sense of humiliation. The model highlights the importance of intrinsic motivation. A rise in the external power's preference for deterrence against terrorism may backfire in these circumstances. Increases in the government's military efficiency against the rebels, who are also terrorists against the government's sponsor, raises overall levels of violence.     

Defence spending and economic growth in South Africa: A supply and demand model*

This paper provides a contribution to the growing corpus of knowledge and understanding of the interaction between economic growth and defence spending in South Africa by specifying a Keynesian simultaneous equation model and estimating the system for the period 1961 to 1997. The model contains a growth equation, a savings equation, a trade balance equation and a military burden equation and when estimated by single equation and systems estimation methods is relatively well specified. There is evidence of an overall negative effect of military spending on the economy over this period, though the significance of individual coefficients is low. There is certainly no evidence of any positive impact, suggesting that cuts in military spending do present an opportunity for improved macroeconomic performance.     

Saudi Arabia's defence offset programmes: Progress,policy and performance

This paper discusses the performance of Saudi Arabia's defence offset programmes. The Kingdom is involved in some of the World's biggest defence offset agreements and a review of the problems it has faced and the policies it has introduced provides a useful insight into that part of the international defence market where trade and development meet.

The paper reviews the origins and development of Saudi Arabia's major defence offset programmes. Saudi policies towards defence offsets are outlined before assessing the practical impact of the programmes themselves. The author concludes that Saudi Arabia's offset projects have had only a minor impact on the Kingdom's economy to date and makes a number of policy recommendations which are designed to enhance the utility of the programmes in the Kingdom's drive to enhance and diversify the technological base of its economy.     

Defence Enterprise Surveys On Market Outlets: The Case Of Slovenia

This article presents the results of an empirical survey of Slovenian defence enterprises focusing on three segmented geographic market outlets: the domestic market, the other European Union (EU-26) markets and the global markets. In the enterprise surveys are included around two-thirds of the domestic defence enterprises of different sizes and activities. The Slovenian defence enterprises by production, supply-in-return, subcontracting, middleman and trader activities in the defence marketing chains are mostly specializing towards the businesses on the domestic market. Rare enterprises are specialized exclusively for activities on the EU-26 markets and the global markets.     

基于3DS的ISAR二维散射点模型仿真

当前,对ISAR成像和目标识别的研究很多,但用于ISAR成像和目标识别的目标模型大都相对简单.建立一种新的ISAR二维散射点模型,生成目标各种姿态的二维散射点数据库.首先选用3DS为散射点生成模型,以此为基础完成模型简化和信息抽取.然后根据目标姿态变化,计算转换坐标,并以F16战斗机为例生成二维散射点图像.最后采用步进频雷达信号对目标散射点模型进行ISAR成像.所建立的目标二维散射点模型可以用于ISAR成像和目标识别研究.     

钨球破片对相控阵雷达天线的冲击损伤仿真

利用非线性动力分析软件LS-DYNA 3D,建立了钨球破片在击穿相控阵雷达天线部件下的毁伤仿真模型.对不同初速度的钨球破片以45°入射角对天线等效靶板的侵彻进行仿真分析,得到了钨球破片整个侵彻作用全过程的完整图像和主要数据.通过对结果图像与数据的分析得出:随着钨球破片初速度增大,剩余速度也会随之增大、击穿靶板所需杀伤动能变大、靶板质量损失变大.结论为相控阵雷达天线的战损快速评估与平时修理提供了科学的依据和参考.
