基于金属膜电阻的大功率低电感负载

利用金属膜电阻设计并制作了用于陡化前沿Marx发生器调试的大功率低电感负载.其阻值约为90Ω,电感约为55nH,基本不具备分散电容.该负载采用线性渐变的圆锥外型结构,有利于减小信号在负载上的反射,配合电容分压器使用能够很好地完成对前沿约为几ns的快前沿高压脉冲的测量.理论估算了该负载的功率容量,并利用PSpice软件模拟了对其进行脉冲方波加载的情况.该负载用于调试陡化前沿的Marx发生器的实验中,获得了幅值约210kV,脉宽近40ns,前沿为5ns的快前沿高压脉冲.多次实验结果表明该负载性能稳定,适用于陡化前沿Marx发生器的调试工作.     

Currency Warfare and Just War: The Ethics of Targeting Currencies in War

ABSTRACT

Is Currency Warfare defined as, the use of monetary or military force directed against an enemy’s monetary power as part of a military campaign, a just way to fight a war? This article explores the ethics of waging currency warfare against the Just War Tradition’s principles of jus in bello (just conduct in war) and its criteria of discrimination and proportionality. The central argument is that currency warfare is inherently indiscriminate but may be proportionate when policy makers consider the nature of the threat confronted and the targeted currency's level of internationalization, that is, to what degree it is used in foreign transactions or used as a foreign currency reserve. I evaluate this argument against historical cases during the Second World War (1939–1945), the Gulf War (1990–1991), subsequent operations against Saddam Hussein in the early 1990s, and the ongoing campaign against ISIS.
