There is a growing view that the emerging brand of Chinese regional diplomacy in recent years is increasingly assertive. This article attempts to make better sense of this perceived more forceful Chinese diplomacy. It argues that Chinese regional behavior is more profitably understood through the lens of a two-pronged foreign policy strategy that combines two particular aspects. One is a tougher and more uncompromising approach toward issues that China regards as concerning its core interests. The other is a more flexible and cooperative position toward interests that, while significant, are of secondary importance.  相似文献

飞网构型设计对提高空间飞网系统的展开抓捕性能具有重要意义。用小弹性模量分析方法对空间飞网构型优化设计问题进行了研究。以绳网中内力分布均衡性为优化目标,选取飞网抛射过程中最大受力时刻为研究工况,赋予绳索单元极小弹性模量,进行静力学计算,并以变形后的结果为初始条件进行迭代分析。优化结果表明,绳网中的内力分布随迭代步数的增加而更趋于均匀。在不改变绳网拓扑结构的前提下,本文所建立的优化设计方法为空间飞网构型优化设计提供了一种参考途径。  相似文献

针对电传动装甲车辆负载功率预测功能缺失导致控制作用滞后的问题,提出一种具有较高负载功率预测精度的实时能量管理策略。在分析整车结构的基础上,采用理论分析和数据拟合方法,建立各动力源数学模型。将差分自回归移动平均模型和自适应马尔可夫链两种预测方法相结合,设计非平稳趋势性负载功率组合预测方法。在非线性模型预测控制框架下,构建多目标优化函数,采用序列二次规划法在有限时域内实时求解最优控制指令,优化多动力源协调控制过程。依托硬件在环仿真平台进行多路面行驶实验,对比有无功率预测的能量管理控制效果。结果表明,改进的实时能量管理策略对未来负载功率具有较好的预见性,能够显著优化多动力源协调控制过程,提升车辆燃油经济性,稳定母线电压和电池荷电状态,对传统模型预测控制下的工程应用场景具有一定借鉴意义。  相似文献

In the late seventeenth century during the Dutch War (1672–1678) and the Nine Years War (1688–1697), French armies relied on small war for the accomplishment of essential tasks and as part of an overall strategy of exhausting their opponents in the Low Countries. The purposes of small war included the imposition of contributions on enemy populations, the destruction of the enemy base of operations, blockades of fortresses, and the general support of campaign armies. The expression ‘small war’ in the French language appeared with growing frequency in the 1690s. Small war can be viewed as both a cause and consequence of the characteristics of these wars. The limited policy goals of Louis XIV the king of France required a strategy that minimised risk and accomplished the goal of reducing if not eliminating the Spanish presence in the Low Countries that bordered the north of France. As French armies increased in size during this period, the demand for specialists at small increased in order to provide security and ensure supply. Small war in the late seventeenth century was thus not ideologically motivated insurgency, but in the minds of French commanders an essential component of strategy and the nature of war.  相似文献

Secret French plans to launch guerrilla-style raids on the British Isles devised in the spring of 1796 were referred to as ‘chouanneries’. The name and concept behind these small-war operations were modelled on the irregular tactics used by the Chouan rebels in the Vendée, which the French state army had brutally quashed, but some wished to transfer into their institutional practice. Part of France's ongoing military strategy in the war against Britain, which included fomenting insurrection in Ireland, these irregular operations were to be manned partially by pardoned deserters and released convicts and prisoners of war. Of these, only Tate's brief invasion of Wales in 1797 was realised, but the surviving plans provide insightful historical lessons into an Anglophobic mindset shared by a small network of practitioners and policy deciders on the effectiveness of such shock and awe tactics. Largely motivated by the desire to take revenge for Britain's support of counter-revolutionaries in the Vendée, these plans could more aptly be referred to as counter-‘chouanneries’.  相似文献

This article fills a gap in the research on Hezbollah by evaluating their military performance from their formation in 1982 and up till the 2006 Israel–Hezbollah war. This study tests the theses that Hezbollah had developed a very strong tactical proficiency in the late 1990s and that there are more similarities in their strategy and tactics during the 2006 war and the 1982–2000 insurgency in Southern Lebanon than previously assumed. Another central theme of this article is how Hezbollah has been constantly adapting and evolving for the duration of its existence.  相似文献

针对径向基插值代理模型样本点预测误差为零时无法获得误差函数进行序列再采样优化的问题,将样本点分布约束引入序列再采样过程,利用潜在最优解加速收敛性,提出一种适用于径向基插值代理模型序列优化的再采样策略,该策略兼顾仿真模型的输出响应特性与样本点的空间分布特性。仿真结果表明,使用该在采样策略后,算法寻优效率和精度均优于传统基于代理模型的优化方法,在对最优解进行有效预测的同时,能显著减少原始模型计算次数。  相似文献
