采用统计法装定系统误差

火控系统由于存在系统误差,现代坦克火控系统均设置了综合修正功能对系统误差进行补偿.现行的实弹射击综合修正量装定方法需要消耗大量弹药,且费时费力.对综合修正量的装定方法进行了分析,并参考美军的做法,提出采用统计法解决综合修正量装定的方案,并给出了该方案的理论基础和适合我军的改进措施.     

城市防空中目标优化分配的模糊聚类分析

定性和定量相结合,利用模糊聚类分析法确定目标的优先防护次序.先构造城市防空中需掩护的目标体系;再依据目标权重建立多因素模糊关系矩阵,导出等价矩阵;最后计算出基于给定参数λ的需防护目标的优先次序,得出目标分类聚类图.变模糊的、复杂的问题为直观的结论,为指挥员合理分配兵力兵器提供可靠的依据,从而最大限度地发挥防空兵器的作战效能.

复杂条件下膨胀土边坡渗流和稳定性分析

膨胀土的工程性质受周围环境及气候的影响比较大,很多膨胀土边坡的失稳破坏是在降雨时或者降雨后发生的。对膨胀土边坡失稳而言,胀缩性和裂隙性是内在因素, 降雨入渗是外部诱发条件。用SEEP／W和SLOPE／W软件对膨胀土渠坡工作期间水位快速升降、降雨入渗以及自然蒸发等可能工况进行了系统分析,并考虑了裂隙的影响。分析结果表明,由于非饱和土的渗透系数很小,渠坡内部各种物理场要经过较长的时间才能达到稳定;水位快速升降对临水面含水量和压力水头的影响较快,需要经过一定时间才能影响渠坡内部的含水量和压力水头变化;膨胀土张裂缝对降雨入渗有显著的影响,含水量和总水头影响范围达到张裂缝底部;水位快速下降会导致边坡安全系数降低。研究结果对边坡稳定性分析很有意义。     

导弹服役年限建模与分析

影响导弹服役年限的主要因素有自然因素、技术因素以及经济因素。合理地确定导弹的服役年限,是减少军费开支、降低导弹全寿命费用的有效途径。从导弹服役年限的概念入手,在提出用经济寿命法确定导弹的服役年限的基础上,通过数学分析,建立经济模型和经济比较模型,确定了导弹服役年限,并结合实例进行了仿真和验证,从而证明了模型的实际应用价值。

破片对反辐射导弹战斗部毁伤效能仿真

分析了“哈姆”反辐射导弹目标特性及破片对其毁伤模式,建立了破片对反辐射导弹战斗部毁伤效能模型,研究了不同质量破片对反辐射导弹战斗部的穿透能力和引爆能力。仿真及试验结果表明：单枚破片质量为15g,速度在1700m/s以上,就足以对反辐射导弹战斗部达到解体性毁伤,它为未来反导弹药战斗部设计提供了重要参考。     

装甲装备器材库存超(欠)储状态分析与程度评价

定义了装甲装备器材库存超(欠)储的概念,提出了维修保障资源点器材储存状态的定性判别和量化方法;考虑数量、时间、空间等影响因素,提出了资源点维修器材超(欠)储程度的评价指标和评价方法,并结合某军区实际数据进行了验证。结果表明:资源点的平均超(欠)储程度反映了保障体系内所有资源点库存偏离正常水平的平均程度,可为确定调剂资源点的优先次序和供应数量提供依据。     

Multinational counterinsurgency: the Western intervention in the Boxer Rebellion 1900–1901

This article proposes a case study of the multinational counterinsurgency operations that occurred in China during the Boxer Rebellion in 1900–1, to provide a better understanding of the political and military dynamics specific to this type of mission. The study focuses primarily on the nature of the cooperation on the ground, the various national approaches to counterinsurgency, and the asymmetry of strategic approach between the Westerners and the Chinese. A discussion is also proposed, highlighting that combined counterinsurgency is not per se an obstacle to the unity of command, but that politically international coalitions create unique challenges to counterinsurgency operations.     

Emotions,Risk Perceptions and Precautionary Actions of Citizens During a Military Operation Using a New Defence Technology: The Israeli Case of the Iron Dome

Abstract

The current field study used unique data collected in Israel in July 2014, during a military operation that the Israel Defence Forces (I.D.F.) conducted in the Gaza Strip, in reaction to the thousands of missiles launched from there into Israel. During this operation, the new Iron Dome anti-missile defence system was used to protect Israelis exposed to missile attacks. The study examined factors that correlate with decisions to comply with I.D.F. defence instructions regarding behaviour during missile attacks. In addition, the study examined the relationship between attitudes towards the Iron Dome technology and emotions, risk perceptions, and the decision to comply with I.D.F. defence instructions. The results indicate that stronger positive opinions towards Iron Dome were correlated with lower levels of fear and anger, and beliefs that participant’s chances of being injured by a missile were lower than they had been during previous military operation. In addition, better compliance with I.D.F. defence instructions correlated with being more fearful, angrier at Hamas, living closer to Gaza Strip, and having more positive opinions about Iron Dome. The findings also indicate gender differences with respect to factors correlated with risk perceptions, opinions regarding Iron Dome, and precautionary actions during attacks.
