African states' attendance at and participation in the preparations for the 2015 Review Conference of the Parties to the Treaty on the Non-proliferation of Nuclear Weapons (NPT) has produced mixed results, with the continent acting as both agent and bystander in respect of certain issues. African agency is evident in, for example, its position as a member of groupings on Iran's nuclear weapons programme and the Middle East Nuclear Weapons Free Zone. Less agency is evident in states' individual actions. This underscores the importance of African states' preference for multilateralism. However, African agency is also less evident in African multilateral efforts at the NPT preparatory meetings. The impact of these developments on the 2015 NPT Review Conference is too soon to tell but may bode ill for African agency.  相似文献

“French nuclear diplomacy” is the French government's use of civilian nuclear cooperation agreements (NCAs) to advance specific commercial and strategic interests. During the heart of the so-called nuclear renaissance, the Élysée Palace aggressively peddled France's nuclear expertise and technology abroad, signing over a dozen new NCAs in an effort to bring in business for the French industry, forge diplomatic relationships, and promote global nonproliferation norms. Several years later, however, the outcomes of France's aggressive global nuclear power push appear nominal at best. This article explores the mixed results of this nuclear campaign, and through three case studies, illustrates how many of France's commercial and political disappointments stem from unrealistic expectations and the disorganization of the French nuclear complex.  相似文献

This article examines Kazakhstani nuclear decision making from December 1991 to May 1992. The study is based on unique archival data and reveals how Kazakhstan's policy makers solved a nuclear dilemma that the nation faced in its first years of independence. The article reconstructs the internal policy-making process behind the decision made by President Nursultan Nazarbayev and his circle of advisors to accept non-nuclear status. The author argues that Almaty elaborated a deliberately ambivalent strategy toward the republic's nuclear status with the aim of maximizing the state's strategic interests. The article reviews external pressures affecting Nazarbayev's course of action and discusses policy options articulated during this period.  相似文献

针对潜艇远航中面临探潜兵力种类多、各兵力间相互联系的特点,将基于贝叶斯网络的故障诊断方法引入到潜艇隐蔽性的评估中。假设通过分析某次远航实例后得到节点分布参数,结合建立的潜艇远航暴露贝叶斯网络图,得出相关结论。初步探讨了该方法对潜艇隐蔽性的评估、诊断暴露原因、确定关键探潜兵力等方面的应用价值。  相似文献

反潜巡逻线中声纳浮标的作战使用与搜潜方法   总被引:1,自引:0,他引:1  
声纳浮标是一种效果好、受地域限制较小、使用方便的探潜设备,利用声纳浮标阵搜索潜艇需要考虑的因素很多,其中最重要的是发现概率。主要研究了使用声纳浮标在巡逻线搜索时的浮标阵的布设方法和布阵要素,讨论了发现可疑信号后对接触进行识别时的浮标布设模型,并分析了浮标间距对巡逻线搜潜的影响,对作战中布设浮标阵有一定参考意义。  相似文献

运用Riccati传递矩阵方法,建立了旋转壳单元的场传递矩阵,推导了肋骨和母线倾角不连续位置的点传递矩阵,在推导中考虑了肋骨各方向可能的变形,编制了用于分析组合加肋旋转壳应力和稳定性的计算机程序(应力程序SAPRi,稳定性程序BAPRi)。利用SAPRi程序和BAPRi程序对潜艇耐压结构的典型结构算例进行了应力和稳定性分析,并将计算结果与理论结果或商用软件(MSC/NASTRAN)的计算结果进行比较,表明该程序结果正确可信,计算速度快,适合于工程应用。  相似文献

ABSTRACT

The making of the Treaty on the Prohibition of Nuclear Weapons (TPNW) has put Austria and its involvement in nuclear disarmament in the spotlight. This study highlights several factors that led Austria to become a prominent voice in nuclear-disarmament debates. First, its involvement dovetails with the emphasis on humanitarian disarmament it has promoted since the 1990s. Second, a strong antinuclear identity pervades Austrian society. This “nuclear allergy” combines antimilitarism inherited from the Cold War and, more broadly, an aversion to nuclear power, including for energy purposes. These two considerations form the background to the increased activism of the Austrian Foreign Ministry on nuclear disarmament in international fora. But, equally, Austria’s crusade for the TPNW can be attributed to the engagement of a small team of diplomats implementing personal as well as national preferences in favor of disarmament.  相似文献
