关于颠覆性技术发展的理性认知

随着美国揭开第三次"抵消战略"重点发展对象的面纱,研发"颠覆性技术"已成为主要军事大国获得技术优势的手段。当前世界新一轮科技革命、产业革命、军事革命交织并行,给颠覆性技术提供了难得的良好机遇。但当我们看见颠覆性技术引领时代新型武器装备潮流发展的同时,也应理性看待其背后潜藏的风险。通过概述总结颠覆性技术研究现状,分析其推动的科技内生性变革,从本质上对其进行理性认知。研究表明,发展颠覆性技术必须积极作为,谨慎对待。     

Development of proxy relationships: a case study of the Lebanese Civil War

Proxy warfare is a consistent element in international warfare. However, it is unclear why proxy relationships form in cases where states have multiple options of groups to support. Existing research identifies the presence of transnational constituencies, shared interstate rivalries, and moderate relative strength of militant groups as highly influential on the development of a proxy relationship. This study examines the presence of these variables within the context of the Lebanese Civil War. The results of this demonstrate that each state places greater importance on some variables and ignores others when choosing a proxy. Additionally, this study further demonstrates the presence of new variables that are key to the development of proxy relationships.

基于多层中转的飞行训练模拟器远程保障系统设计

随着飞行模拟训练在我国的常态化、普及化发展,模拟装备的保障压力也日益增长,为了有效缓解保障压力增长与保障力量薄弱之间的突出矛盾,提出一种基于多层中转跨网络的飞行训练模拟器远程保障系统。该系统依托现有的专用网资源建立从技术保障中心到远程模拟器的数据通道,通过在不同网段间架设中转服务器的方法为技术保障人员提供从专用网到模拟器局域网计算机的通信链路,从而辅助技术保障人员对远程模拟器进行远程保障。目前,该系统已在空军多个部队进行了部署和应用,使用结果表明,该系统的应用和推广能大大拉直模拟装备的保障路径,缩短排故时间,节省维护经费。

以高超声速飞行器为研究对象,构建快速准确计算高超声速飞行器无黏边界层外缘参数的计算方法。拟合空气比热、比热比随温度变化曲线,建立空气属性温度划分准则。基于不同空气属性建立高超声速飞行器边界层外缘参数工程与数值计算模型,采用钝双锥模型,对比分析工程估算、无黏数值及有黏数值计算方法的计算结果。结果表明,0°攻角状态下,基于无黏流场的数值计算与工程估算和有黏数值计算的压强最大差值分别为1.19%和2.39%;10°攻角状态下,最大差值分别为5%和50%;从而证明所提出的无黏数值计算方法明显优于工程计算方法,为进一步快速准确计算高超声速飞行器气动热环境奠定了重要基础。     

基于DOB和二自由度控制器的某火炮稳定控制系统设计

火炮稳定控制系统性能会受到如路况、火炮射击时产生的冲击力矩等外部扰动以及摩擦力矩变化、测量噪声、转动惯量变化等内部参数摄动的影响。针对此问题,引入一种DOB观测器和二自由度控制算法,来减少摩擦对系统性能的影响,提高系统对载体扰动的隔离能力。仿真和实验结果表明,所提出的算法可以有效提高系统的稳定精度和速度伺服性能。

针对装甲机械化部队射手素质评价存在的评价内容不全、指标选取不合理等诸多问题,提出了一种基于层次分析法(AHP)和模糊评价法的射手综合素质的三级模糊综合评判模型。首先,在对射手综合素质深刻剖析的基础上,建立了射手综合素质评价指标体系,并运用层次分析法确定了各指标权重;然后,运用模糊综合评价法构建了射手综合素质的三级模糊综合评判模型;最后,通过实例验证了该模型的科学性与实用性。     

The relevance of the Gulf of Guinea in global energy politics

Africa and for that matter the Gulf of Guinea cannot be indifferent to the global energy politics of the 21st century. The increasing importance of the region has attracted major actors in the energy sector. The competing interests of these actors are played out in various forms. This heightened interest in the region, especially with the discovery of oil in huge commercial quantities, has brought the importance of the area into focus in global oil politics. This paper looks at the importance of the region in light of the huge energy potentials of the Gulf of Guinea and how the institution of proper governance systems could serve as an important factor in ensuring the proper management of the resource.     

Military support and transnational terrorism

Analysing the relationship between the provision of military support and the probability of becoming the target of a terrorist attack, this paper contributes to the literature on the causes of transnational terrorism. We find that deployment of military troops of country X in country Y increases the probability of a terrorist attack on citizens of country X by a terrorist group located in country Y. Exporting weapons to country Y seems to increase the probability of being attacked by the terrorists of this country Y as well. Deploying materials, however, does not seem to significantly influence the probability of attack. Including lagged values for our military support variables ensures that the causality direction is from military support to terrorist attacks. Moreover, these results indicate that while the effect of military deployment on the probability of attack lasts for more than 1 year, the effect is rather short-lived.
