一种含氧混合燃料喷雾特性的试验研究

针对柴油和所需的油料方案B20D10（即在柴油中掺混20%生物柴油和10%碳酸二甲酯,Dimethyl-Carbonate,DMC）,在某型重型车辆柴油机高压泵试验台上,采用定容弹和高速摄影技术,研究了掺混生物柴油和DMC后对燃油喷雾特性的影响。结果表明：在不同的背景压力下,燃料B20D10油束的贯穿距离低于柴油,最大降幅达到7.0%,锥角最大增加约15.2%;在非破碎阶段,燃料的贯穿距离与时间呈正比关系;在破碎阶段,贯穿距离与时间的关系为s∝tn,其中n约为0.57。试验结果为建立该混合燃料的喷雾模型,并进行缸内燃烧的数值模拟奠定了基础。

MIDDLE EAST NONPROLIFERATION

The Middle East is a crucial region for the global nonproliferation regime. In 2010, the state parties to the Treaty on the Non-Proliferation of Nuclear Weapons proposed a conference on a Middle East Weapons of Mass Destruction-Free Zone. The nuclear weapon-free zone model, on which this idea builds, has achieved important results in other regions, but faces especially stark challenges in the Middle East. However, the attempt to apply the boldly imaginative zone approach to the Middle East holds promise for building a more inclusive dialogue on nonproliferation and regional security.     

RELIABLE ENERGY SUPPLY AND NONPROLIFERATION

The phenomenon of global warming has led to a revival of the prospects for increased nuclear energy production worldwide, yet such increased production carries with it the increased risk of proliferation. To mitigate this risk, various multinational arrangements have been proposed to provide reliable supply of nuclear fuel while at the same time discouraging the construction of national plants for nuclear enrichment and reprocessing. This article provides a brief history of some of these proposals and concludes that the likelihood of success for such schemes as effective tools for nonproliferation is not high at this time. A proposal from the World Council on Renewable Energy to expand the understanding of supplier obligations under Article IV of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) to include the development of non-nuclear energy technologies for NPT parties in good standing is potentially a much better nonproliferation tool. Such an approach tracks the ideas contained in Title V of the Nuclear Non-Proliferation Act of 1978, which has recently received revived congressional interest.     

LDO稳压器敏感度建模与仿真技术研究

基于LDO稳压器在电磁干扰（EMI）下产生直流偏移失效的机理分析,展开敏感度建模与仿真方法研究。使用一款实验芯片,创新地引入片上电压传感器,用于测试EMI在LDO稳压器内部的传播特性。在敏感度建模中,建立等效电路模型,通过直流功能测试,Z参数阻抗特性测试验证模型的正确性,将该模型用于LDO稳压器的敏感度预测。在敏感度仿真过程中,通过分析关键子电路和不断增加寄生元件,仿真不同寄生因素对敏感度影响的权重。将仿真结果与传导直接注入法（DPI）片上测试结果对比,仿真结果与DPI测试在频域1MHz至1GHz匹配。     

On the Road to the 2015 NPT Review Conference

The second session of the Preparatory Committee for the 2015 Review Conference (RevCon) of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) highlighted two issues in particular—progress toward a Middle East Weapons of Mass Destruction–Free Zone and the Joint Statement on the humanitarian impact of nuclear weapons—that may not only greatly affect the health and vitality of the NPT and the 2015 RevCon, but possibly also have implications for the international nonproliferation regime as a whole. Dr. William Potter, director of the James Martin Center for Nonproliferation Studies, interviewed Ambassador Cornel Feruta, chairman of the 2013 PrepCom, to discuss these and other issues related to the meeting and the future of the treaty and its review process.     

相控阵雷达外场试验目标模拟技术

针对传统雷达回波模拟技术模拟目标态势单一、建设成本高、灵活性差等缺陷,结合相控阵雷达快速波束定向的扫描特点,提出了一种基于射频存储转发技术和移动阵列平台的相控阵雷达外场试验目标模拟方法。该方法采用射频空间辐射注入的方式为雷达提供较为逼真的三维空间模拟目标回波信号和构建较为复杂的模拟目标场景态势,能够支持包括雷达天线在内的整个雷达系统进行模拟试验或训练。最后通过实例仿真验证了该方法的有效性和可实现性。
