核电磁脉冲对单片机系统的辐照效应研究

核爆炸产生的电磁脉冲的“杀伤”范围极广,它可使距离爆心投影点几千公里的电气设备、电子装备和系统的工作失灵甚至破坏。为了研究它对单片机的各种效应,利用GTEM室产生的模拟核电磁脉冲,对单片机系统进行了辐照效应实验。实验表明,单片机系统在核电磁脉冲作用下,会出现“死机”、重启动、控制状态的改变、通讯错误和外部RAM内容改变以及数据采集误差增大等现象。在实验基础上,研究了单片机系统的各种效应产生的原因。

Let’s make a (nuclear) deal: Bargaining,credibility, and the third offset strategy

An institutional perspective on nuclear deterrence cooperation within alliances has the potential to fundamentally reorient how we think about analyzing nuclear and deterrence decision-making between nuclear patrons and non-nuclear clients. It comes at a time when the presidency of Donald Trump is sure to test many of the core claims and assumptions in security studies, especially relating to bargaining and credibility within alliances. This article surveys questions that will be core to the research agenda involving alliance institutions and nuclear weapons during the Trump presidency and beyond.     

Enhancing Political Cohesion in NATO during the 1950s or: How it Learned to Stop Worrying and Love the (Tactical) Bomb

This article argues that the perceived need by NATO to nurture political cohesion within the Alliance during the 1950s resulted in the adoption of strategic concepts that were out-of-step with the military environment in which it was operating. It maintains that the Alliance acquiesced to American leadership on nuclear issues which led to the development of tactical nuclear capabilities at the expense of conventional war-fighting capabilities for the defence of the European Central Front. This resulted in a strategic concept that enhanced political cohesion but was militarily unviable.     

Nuclear opportunism: A theory of how states use nuclear weapons in international politics

How do states use nuclear weapons to achieve their goals in international politics? Nuclear weapons can influence state decisions about a range of strategic choices relating to military aggression, the scope of foreign policy objectives, and relations with allies. The article offers a theory to explain why emerging nuclear powers use nuclear weapons to facilitate different foreign policies: becoming more or less aggressive; providing additional support to allies or proxies, seeking independence from allies; or expanding the state’s goals in international politics. I argue that a state’s choices depend on the presence of severe territorial threats or an ongoing war, the presence of allies that provide for the state’s security, and whether the state is increasing in relative power. The conclusion discusses implications of the argument for our understanding of nuclear weapons and the history of proliferation, and nonproliferation policy today.     

How durable is the nuclear weapons taboo?

The nuclear weapons taboo is considered one of the strongest norms in international politics. A prohibition against using nuclear weapons has seemingly shaped state behavior for nearly seven decades and, according to some observers, made nuclear use ‘unthinkable’ today or in the future. Although scholars have shown that nuclear aversion has affected decision-making behavior, important questions about the nuclear taboo remain unanswered. This article seeks to answer a basic question: How durable is the taboo? We develop different predictions about norm durability depending on whether the taboo is based primarily on moral logic or strategic logic. We use the comparable case of the norm against strategic bombing in the 20th century to evaluate these hypotheses. The logic and evidence presented in this paper suggest that the norm of nuclear non-use is much more fragile than most analysts understand.
