Lost through non-translation: bringing Clausewitz's writings on ‘new wars’ back in

While Carl von Clausewitz has generally been respected as one of the most profound philosophers of war, his expertise has been regarded as somewhat limited if not even irrelevant to the so-called ‘new wars’ of the post-Cold War world. Many scholars in international relations have claimed that ‘new wars’ are essentially ‘post-Clausewitzian’ and ‘post-trinitarian’ in nature, meaning that they are no longer fathomable through a Clausewitzian framework. However Clausewitz's earlier writings were nearly exclusively dedicated to guerrilla warfare, or what he called ‘small wars’. These writings have been largely overlooked by many analysts of contemporary conflicts. By drawing on his rare and untranslated writings, the article uncovers a critical part of Clausewitz's expertise in asymmetric warfare and shows that, far from being irrelevant in an age where interstate warfare is increasingly being replaced by conflicts between states and semi-/non-state actors, Clausewitz's philosophical writings actually shed new light into the particular interactive dynamics generated during wars waged under conditions of asymmetry.     

基于车辆稳态动力学特性的汽车动态轨迹规划

针对高动态环境下驾驶辅助系统（ADAS）的轨迹规划问题,提出基于车辆稳态动力学特性的动态轨迹规划算法。该算法首先在交通车轨迹预估基础上建立搜索空间,接着利用车辆稳态动力学模型作为轨迹发生器,在搜索空间中对轨迹发生器产生的轨迹进行评价,最后根据驾驶意图和优化条件选择最优轨迹。文章采用基于最优加速度预瞄理论的轨迹跟踪算法,建立了七自由度车辆动力学模型,并在Simulink环境下搭建仿真平台,进行超车仿真实验。实验结果表明,本文提出的算法可行、有效。     

带点缺陷的一维亥姆霍兹共振腔声子晶体中缺陷模式

在基于亥姆霍兹共振腔的一维声子晶体中引入点缺陷会在原有局域共振型声禁带内产生缺陷模式。采用传递矩阵法和有限元法分析了缺陷模式随缺陷单元几何尺寸变化关系和声子晶体中声场分布情况。结果表明,随着缺陷单元与完美单元之间耦合程度的增强,缺陷模式从局域共振型禁带中完美单元共振频率处向禁带边缘移动。同时,缺陷模式的存在使得结构中出现了能量局域化的现象。本工作对设计新型声滤波器、能量集中装置具有一定的理论意义。     

An Imperfect Jewel: Military Theory and the Military Profession

This article explores a perennial theme in the literature of strategic studies: the relationship between military theory and the military profession. It begins with a conceptual analysis of this relationship. It then investigates what military theorists themselves have had to say about the utility of their craft. It concludes by assessing the actual influence of military theory on selected individuals and institutions. The individuals are George S. Patton, Jr., and Ulysses S. Grant. The institutions are the United States Army and the United States Air Force in the late twentieth century. The fundamental finding is suggested in the title: military theory can indeed be quite useful in the maturation of military commanders and in the development of martial institutions, but it is not always necessary and by no means perfect. It should thus be studied assiduously but used with caution.     

监视雷达低仰角测角方法分析与工程实现

监视雷达天线孔径较小、垂直波束较宽,当雷达天线低仰角探测目标时,波束打地严重,测量易受多路径影响,仰角测量精度难以满足要求.先对现代雷达常用的和差比幅与比相两种测角方法进行了分析,然后以相控阵天线为例,对两者在低仰角下的测向精度进行了仿真和深入分析.最后结合两种方法的优缺点,对某Ⅰ型监视雷达样机进行改进,使其满足比幅比相混合型测角的条件,并对改进后的样机作动态对比试验,再次证明两种常用测角算法在低仰角下的优劣,为工程应用提供参考.

关于计量经济学案例教学的探讨

计量经济学包含理论教学、实验教学、案例教学三个教学环节,案例教学作为联系理论教学与实验教学的桥梁与纽带,在计量经济学教学中起着重要的作用。但目前计量经济学案例教学仍存在对案例教学法认识不够、案例资源匮乏、案例选择使用不当等问题。针对这些问题,本文提出了正确处理理论教学与案例教学关系、编撰经典案例集、准确选择使用案例等一些具体的改革措施与建议,以提高计量经济学教学效果。
