Protection of armoured vehicles against chemical,biological and radiological contamination

The article presents problems related to mechanical protection of vehicles with different add-on armours against chemical,biological and radiological contamination.This applies to vehicles with additional passive,reactive and hybrid protection in the form of cassettes against piercing with anti-tank pro-jectiles,piercing with their kinetic energy of impact,and as a result of chemical energy of shaped charges as well as explosively formed projectiles.It has been shown how increased ballistic protection of these vehicles at the same time reduces their decontaminability in various places of the vehicle due to the increased additional surface of the vehicle with cassettes.Prevention of contamination of these cassettes has been presented as a way of reducing hard to reach surface for decontamination and a method of insulating construction elements(stands),fixing these cassettes to the vehicle,from the environment to prevent contact with contaminated liquids and dusts.The selection of appropriate materials is shown,which may affect the improvement of the decontamination efficiency of the vehicle with such cassettes.This applies to the use of materials with low absorption of chemical warfare agents,which prevent the accumulation of large amounts of these agents on contaminated surfaces and improve the effectiveness of decontamination.It also shows how to ensure better access of the disinfectant to as much of the vehicle surface as possible,covered with cassettes that have been contaminated.It shows how a vehicle,in particular with such cassettes,can provide protection against radar detection when Radar Absorbent Material is used on vehicle cassettes.     

应对混合战争的人防工程安检设施设置研究

冷战结束后,"混合战争"的威胁日益增加,人民防空工程和其他各类城市安全设施都亟需改进安全防护手段,增设安全检查设施,防控敌对势力的恐怖袭击和后方破坏。人防工程在战时对于出入口通行效率的要求远比地铁设施高,且出入口区域空间有限,无法照搬现有的地铁安检措施。本文从防范标准、安检流程以及技术手段等方面进行分析,提出运用新的检查技术手段,结合"分类检查与人物分离"的新检查流程,在人防工程出入口有限的空间条件下,设置人员和物品各自的分级检查通道。这在经济可承受的范围内既满足了筛查质量,又保证了检测通行效率,从而能够达到人防工程掩蔽与安检的要求,并完善应对"混合战争"威胁的措施,以期为增强我国未来的整体国防实力提供借鉴。     

基于复杂网络的机群作战建模与仿真

机群作战已成为战争中的主要作战形式之一。而传统的作战模型,已经不适应其多任务驱动、多机种协作的机群作战特性。为此,以复杂网络为基础,提出了一种构造不同类型的节点连接的动态生成算法,构建了反映真实作战场景的网络描述模型,较好地呈现出了机群作战中的涌现性、模糊性等诸多性质。并提出了描述机群作战网络的统计特征量,通过破击仿真实验,得出了与战争事实相符合的结论,为未来研究机群作战体系效能评估打下了基础。     

北斗卫星导航系统商业化发展策略

为应对海军在全球公域投送力量时面临的严重"反介入/区域拒止"(anti-access/areal denial,A2/AD)挑战,美国海军利用电磁作战方面的技术优势,率先提出并重点发展了"电磁机动战"。虽然该理论还处于进一步完善当中,但随着研究和实施的深入,将有助于提高美国海军在电磁领域的作战优势。     

论中国现代散文的“情”、“志”之美

"情"与"志"是构成现代散文的重要因素之一。散文的"情"与"志"的要求是真实、新颖、深湛,言近而意深,纸短而情长。散文要确立真实、新颖而深湛的"情"、"志",还要注重两者的融合。散文中说理、言志的方式多种多样。

Applying Lanchester's linear law to model the Ardennes campaign

In modern warfare, many believe the decisive factor in winning a battle is seizing the right moment to shift from defense to attack, or vice versa. This paper attempts to bring that perspective to Lanchester's differential equations of warfare, and continues the application of Lanchester's linear law to the analysis of the World War II battle of Ardennes, as reported in earlier issues of Naval Research Logistics by Bracken and by Fricker. A new variable, shift time, accounting for the timing of the shift between defense and attack is explicitly included in our version of the model, and it helps obtain improved goodness of fit to historical data. © 2001 John Wiley & Sons, Inc.
