发展中的高超声速武器及其战略意义 总被引:3,自引:0,他引:3
速度是武器系统的一项重要指标,高超声速武器技术是武器技术发展中的一个重要里程碑,是自隐身技术问世以来在军事技术方面最重要的进展。高超声速武器将成为未来空天力量对抗中至关重要的武器,对于未来战争的作战模式、作战过程及战争结局将产生重大影响。目前,军事大国和一些发达国家都已制定了一系列高超声速武器发展计划,研究与试验工作也取得了重大进展。 相似文献

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. 相似文献

It is commonly assumed in the foreign policy literature that narratives are uniquely persuasive and thus integral to obtaining public support for war. Yet, empirical research on “strategic narrative” is often vague on both the concept of narrative and how it persuades. Moreover, the stories publics use to interpret war are rarely examined. This paper offers a novel approach to studying “from the ground up” the war stories of individual British citizens. It examines public interpretations of war through emplotment: the way people select and link events to create a coherent story. Examining the wars people include and those they silence, it illustrates how a diverse range of citizens morally evaluates Britain’s military role, be it as a Force for Good, a Force for Ill or a country Learning from its Mistakes. In doing so, the paper offers an alternative methodological approach to studying how individual citizens understand war. 相似文献

The British Military Covenant can be located in and from many sources and from 2011 onwards in primary legislation. This article argues that the provision of military housing amounts to an early test of how the military covenant is understood and used by those involved in defence policy, and those in the armed forces affected by it. It finds that housing was a prominent feature of how service personnel understood how they were valued, but was not explicitly understood as a covenant issue by those personnel or the officials in charge of the Defence Estates. We locate three reasons for this: (1) the covenant has been poorly translated from aspiration into policy practice, (2) the covenant is unevenly understood across its stakeholders which has the effect of generating disappointment through misaligned expectations, (3) those engaged in the reform process surrounding the Defence Infrastructure Organisation (DIO) saw the covenant as a means to energise reform. Ultimately housing was seen as a dry and technocratic business area and thus an issue ripe for being refracted through the covenant was ultimately left outside of its remit. 相似文献
