预应力作用超磁致伸缩材料磁滞回线的温度敏感性分析

超磁致伸缩材料Terfenol-D具有应力温度敏感特性。通过循环油浴加热的实验方法,测量超磁致伸缩材料在力热磁耦合下的磁滞回线,发现预应力的增加有效降低了温度对材料低磁场性能的影响,材料显示了良好的低磁场温度稳定性能。试件在高预应力120 MPa、磁场强度300 kA/m的条件,磁化强度出现先增大后减小的现象,磁化衰减幅度得到减弱。     

At war with social theory: Instrumental and communicative action in US military doctrine during the War on Terror

As US counterinsurgency campaigns draw to a close, doctrine for asymmetric warfare written during the War on Terror has come under heavy criticism. While many have argued that this shift to ‘winning hearts and minds’ is evidence that the United States is taking humanitarianism and nation-building seriously, others argue that a wide gap exists between US counterinsurgency doctrine and the protection of civilians afflicted by conflict. In this article, I show that the latter is true by comparing theories of instrumental and communicative action to US doctrine for operational design, stability operations, and counterinsurgency. I argue that these texts treat the people as an object to be manipulated for the achievement of pre-determined self-interested strategic goals rather than members of a community that jointly designs operations to fulfill shared objectives. However, US doctrine does contain communicative elements that, if prioritized, would better support humanitarian and state-building objectives otherwise subordinated in the War on Terror.     

超声速转弯流道内迟滞现象的初步研究

采用特征线法,通过预先给定中心线马赫数分布,设计了消波的二维超声速转弯流道。研究了不同反压作用下转弯流道内的激波串结构、壁面沿程静压分布和壁面分离区演化等特征,分析了流道内激波串波结构与反压的关系,发现了激波串波头很难稳定在流道拐点附近。当激波串波头靠近流道拐点时,流场具有双解。流动双解区向单解区演化过程中,伴随有大分离区在上、下壁面之间的迅速转换和激波串结构的快速演化。

基于功率控制的水下声学传感器网络部署

目前对在传感器网络部署优化的研究中,主要集中在二维传感器部署优化的研究上,对水下三维传感器网络的部署研究特别是以优化网络资源、延长网络寿命为目的水下传感器网络非均匀部署的研究较少。改进了现有传感器探测模型,建立探测功率与传感半径的关系,结合体心立方格覆盖方案,建立了水下传感器网络非均匀部署模型,仿真实验表明,非均匀部署模型有效地控制了节点部署密度,平衡了网络能量,相对于均匀部署模型显著提高了网络寿命。     

濒海战斗舰——美国海军新型装备

美国海军称濒海战斗舰（LCS）是一种适于近海复杂水情的快速、高度机动的水面作战平台。海湾战争之后,美军为了加强水面舰艇对地攻击、加强机动性和适应削减军费的形势,濒海战舰应运而生一跃成为当今世界武器的新宠。LCS具有单体和三体两种船体,根据三种作战任务实现模块化重构。尽管发展十多年来LCS在功能设计和火力配置上远远未达到军方的要求,被人指责为＂中看不中用＂,尽管LCS的费效比一直为美国国会所诟病,然而,LCS的建造代表着美国海军作战理念的战略转型。美海军在LCS的快速灵活、续航能力、武器装备方面不断寻求最优组合,以达到其控制亚太和世界海洋权的目的。文章较为系统地介绍美国LCS崛起的原因、发展历史、战术技术性能及近期发展动态。     

The Peninsular War guerrilla and its antecedents: humiliation forgotten,disaster prefigured: the guerra fantástica of 1762

ABSTRACT

The brief war that took place between Spain and Portugal in 1762 is one of the least known episodes in the latter’s military history, whereas, thanks to Wellington’s construction of the Lines of Torres Vedras, the French invasion of 1810–11 is right at the other end of the spectrum. Yet the two episodes are closely linked to one another. At the very least, they are uncannily reminiscent in terms of their details – in both cases substantial foreign armies were vanquished through a combination of irregular resistance, scorched-earth tactics and the clever use of field fortifications – and the article therefore argues that Wellington based the plan that defeated the forces of Marshal Massena on the strategy used by the Portuguese half a century earlier.     

电磁发射用分段供电六相圆筒式直线感应电动机数学模型

为研究新型分段供电六相圆筒式直线感应电动机的运行规律，针对其不对称运行的特点，采用磁动势理论推导了气隙中与空间位置无关的脉振磁场的电感矩阵表达式，通过将其引入abc坐标系下对称的电机数学模型，从而构建了描述六相圆筒式直线感应电机不对称的数学模型。在Simulink环境下，采用隐式梯形法构建了该不对称模型的系统仿真模型。最后，对样机进行了仿真分析和实验验证，仿真结果与实验数据吻合良好，验证了模型的正确性。
