Theories of Non-Balancing and Russia’s Foreign Policy

The beginning of the twenty-first century has witnessed the emergence of balancing responses to the US hegemony, among which Russia’s foreign policies stand out as corresponding to what is understood as ‘hard balancing.’ Why is the United States being balanced against? This paper categorizes the existing theories of non-balancing into six conditions that together guarantee the absence of balancing and demonstrates that the current unipolar system can satisfy only one of them. This eases the systemic constraints and makes balancing possible. The paper then presents three cases of balancing with reference to President Putin’s foreign policy. It argues that even though in terms of relative military capabilities unipolarity still holds, the emergence of counter-hegemonic balancing is indicative of important changes in the nature of post-Cold War American domination.     

Effective in battle: conceptualizing soldiers’ combat effectiveness*

How do we understand combat effectiveness – soldiers’ performance in battle? Despite the broad consensus that understanding combat effectiveness is important both for scholars and policymakers, there is widespread disagreement about what combat effectiveness is. More specifically, studies of effectiveness tend to focus on either the skill of soldiers in battle, or their will to fight. Yet both skill and will are essential components of an effective fighting force. This article argues that understanding combat effectiveness requires understanding both of these key components of effectiveness. In other words, combat effectiveness requires both the skill and will to engage the enemy in an organized manner. It then demonstrates the usefulness of this conceptualization by applying it to the cases of British, Indian, and Australian forces fighting the Japanese during the Second World War. Only when scholars are talking about the same concept will our understanding of the conditions under which militaries are effective in battle progress. By comparing different units fighting the same opponent under the same material conditions, I demonstrate that units vary both in their combat skill and their will to fight, and that understanding their effectiveness in battle requires analyzing both of these key factors.     

矩阵开关技术在通用ATS电源模块自检中的应用

针对通用ATS中电源模块检查过程中存在检查时间长、劳动量大、工作效率低且易出错等问题,将矩阵开关技术引入通用ATS中电源模块的自检过程中,选取电压信号的均值和均方差作为评价电源模块性能的特征参数,并利用矩阵开关的多路复用功能设计了电源模块自检的拓扑结构,实现了自检过程中多通道的自动配置。仿真验证试验说明了该方法具有多通道自动配置、自检时间短、故障定位准确等优点。     

我国军事权的宪法规制

在我国,军事权是国家权力体系中一项独立的权力,它是中央军事委员会及其所属各级军事机关依照宪法授权而享有的对武装力量进行统率和管理的一切支配力的总和。我国历史上出现过的十几部宪法或宪法性文件均对其作出了规定。现行的＂八二宪法＂更是对军事权的权力来源、权力主体、权力范围、权力结构、启动程序和行使结果进行了较为完善的规制。在这些宪法规制的框架下,我们寻求着军事权的＂增强＂与＂节制＂这对二律背反的精妙平衡。

广州日总太阳辐射估算

利用广州十年内（1995—2004）的气象数据,进行了逐步回归分析,得出估算日总太阳辐射的模型。并通过平均百分误差、平均偏差和均方根误差对各模型的精确性进行了对比,选择出最优模型。最后用实测的日总太阳辐射数据对选出的最优模型进行验证,结果表明,当日总太阳辐射值较大时,模型估算值与实测数据吻合得很好。

超音速等离子制备Al/Ni涂层的性能特点

以超音速等离子喷涂系统(HEPJet)为平台,采用铝包镍(Al/Ni)自粘结粉末,借助Spray Watch2i在线监测系统、扫描电子显微镜(SEM)、X射线衍射仪(XRD)和WE-10A万能拉伸试验机,研究了超音速等离子喷涂Al/Ni粒子的速度、温度及涂层的组织性能。研究结果表明:超音速等离子喷涂Al/Ni自粘结粉末时,与普通火焰喷涂不同,射流中无明显的放热反应特征,涂层中也未发现Al-Ni化合物;超音速等离子的喷涂功率、喷涂距离等参数对Al/Ni喷涂粒子的状态和涂层组织性能影响显著,当功率为54.6kW、喷涂距离为150mm时,Al/Ni涂层组织致密,与基体的结合强度高达56MPa。

两跳OFDM译码转发中继系统的功率分配研究

分析了系统总功率约束和各节点独立功率约束条件下的中继信道,提出了以最大化系统容量为准则的两跳中继系统联合子载波配对和功率优化分配算法。算法先进行子载波配对,然后选出一组信道增益最大的子载波进行平均功率分配,最后通过迭代得到功率分配结果。为了进一步降低系统复杂度,我们利用相邻子载波之间的相关性,用若干相邻子载波组成一个等效子信道。仿真结果表明,所提算法可以在大大降低反馈量的情况下达到和注水功率分配几乎相同的系统容量。
