CALLING FOR ACTION

International Atomic Energy Agency (IAEA) safeguards are under more stress today than at any time in their history. Compliance concerns, a shortage of resources and technology, and growing responsibilities threaten to undermine the effectiveness and credibility of this vital and fundamental pillar of the nonproliferation regime. To address this challenge, the United States recently launched the Next Generation Safeguards Initiative. The goal of this initiative is to ensure the IAEA makes the fullest possible use of its existing authority to prevent the diversion of safeguarded material and to investigate suspicious activities. The initiative will advance state-of-the-art technology, foster the development of a new generation of safeguards experts, and promote technology collaborations and safeguards-conscious infrastructure in states using or pursuing nuclear power. Although it has a domestic focus, the initiative's intent is to catalyze a much broader commitment to international safeguards in partnership with other governments and the IAEA.     

VERIFIABILITY,RELIABILITY, AND NATIONAL SECURITY

The rejection of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) by the U.S. Senate in October 1999 could have been avoided, and the consequences of that vote still loom in the minds of supporters of the treaty. President Barack Obama has embraced the vision of a world free of nuclear weapons, and a key element of the Obama administration's arms control agenda is delivering on U.S. CTBT ratification. In order to secure the two-thirds majority in the Senate necessary to ratify the treaty, senators that remain skeptical of nuclear disarmament must also be convinced that the entry into force of the CTBT is in the national security interest of the United States. This article provides an analysis of the issues surrounding U.S. CTBT ratification divided into three segments—verifiability of the treaty, reliability of the U.S. stockpile, and the treaty's impact on U.S. national security—and concludes that CTBT ratification serves the security objectives of the United States. The CTBT constitutes an integral component of the multilateral nonproliferation architecture designed to prevent the proliferation of nuclear weapons, and it constrains the qualitative development of nuclear weapons, thereby hindering efforts by states of concern to develop advanced nuclear weapons.

多目标多决策者环境下防空反导装备体系资源分配与优化

作战体系具有层次高、规模大,各作战分系统间协调配合密切的特征。在作战任务中,这种多层次、多系统、多决策者、多目标的结构使得对各作战子系统的武器装备分配变得更为复杂。为解决此类复杂结构的优化问题,在层次化多目标分析方法基础之上,将层次系统的风险管理引入到模型中来,形成多目标多决策者资源分配模型多目标多决策者资源分配模型,用以解决在不确定风险环境下进行多目标资源分配的问题。利用MOMDRA模型建模空袭风险下防空反导体系的武器装备分配问题,在求解该模型的过程中采用系统分解的思路,利用权重法,站在不同决策者的角度得到该体系的Pareto最优资源分配方案,并通过一个实例来说明此方法的可行性。     

The Odyssey of the Comprehensive Nuclear-Test-Ban Treaty

This study examines the failures of the William J. Clinton and Barack Obama administrations to secure ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). It applies an integrated analytical framework for assessing treaty ratification that builds upon previous research in order to understand why the Clinton administration failed to achieve CTBT ratification in 1999 and why the Obama administration has so far failed to advance the treaty in the Senate. The study concludes that CTBT ratification, despite Obama administration pledges of support, remains highly unlikely. Finally, the study analyzes the common domestic political factors present in both cases and suggests areas for further research.     

舰载近区防卫武器综合运用

水面舰艇近区防卫武器的作战运用研究是舰载武器作战运用研究的新课题。在分析近区防卫目标特征、武器特点、作战方法的基础上,提出近区防卫武器综合运用一般原则,基于作战时域的连续性及效果的叠加性,构建近区防卫武器使用逻辑结构,建立武器运用的对策模型,可为近区防卫武器的科学使用提供理论参考。     

空腔噪声非线性数值模拟

将雷诺平均N-S方程与非线性噪声求解方法相结合,对M219空腔在Ma=0.6,Ma=0.85,Ma=1.35条件下进行了气动噪声分析。通过雷诺平均N-S方程求解空腔流场,得到包含空腔平均流场基本特征以及强制设定的湍流脉动统计描述的初始湍流统计平均解,采用非线性噪声求解方法重构噪声源并高精度模拟压力脉动的传播。通过与试验结果对比表明非线性噪声求解方法能够较好地捕捉空腔流动中的压强脉动及噪声水平。与分离涡模拟方法相比,非线性噪声求解方法在保持计算精度的同时大大减少计算网格,对内埋弹舱快速设计具有一定的参考意义。     

高功率微波武器攻击卫星有效载荷系统可行性分析

高功率微波武器是近几年发展起来的定向能武器之一,被认为是在未来制天权争夺的战场上对卫星有效载荷最大的威胁之一.首先对高功率微波武器的关键技术及技术途径进行了讨论,然后描述了高功率微波对目标损伤的机理和耦合途径,最后根据高功率微波的不同耦合途径对卫星有效载荷受到攻击的可行性进行了详细的分析,计算结果表明,高功率微波武器在高峰值功率或距离很近的情况下都会对未进行电磁加固的卫星有效载荷产生损害.     

Russia,America and missile defense

Russia has sharply objected to US plans for ballistic missile defense. The Russian official explanation is that the real purpose of the US missile defense plan is to make it impossible for Russia to retaliate against a US nuclear (or massive conventional) attack, thus making Russia subject to military blackmail by the US. The Russian response has been the result of a sum total of various factors, mostly political and cultural, while the technical capabilities of the proposed system have played a secondary role.
