氧化钨薄膜电致变色机理的探讨

研究磁控溅射生成的氧化钨薄膜处于电解液系列中的循环伏安特性,充电电流及光学特性.采用配体场理论来解释氧化钨薄膜在电场作用下,锂离子注入引起薄膜变色的现象,认为注入的锂离子破坏了薄膜界面层内氧化钨分子的八面体结构的对称性,在内部静电场和外部电场的共同作用下,钨离子d轨道的五重简并能级分裂,从而使得薄膜对可见光产生d-d吸收,导致氧化钨薄膜变色.     

Models of scientific and technological review for the Biological and Toxin Weapons Convention

ABSTRACT

Science and technology (S&T) review is key to anticipating developments in the life sciences that may benefit or run contrary to the aims of the 1972 Biological and Toxin Weapons Convention. It serves as a mechanism for both preparing against novel biological threats and identifying the best opportunities for developing and sharing the life sciences to the fullest extent. In the age of rapidly advancing biotechnology, S&T review needs to be wide ranging, involve a diverse set of inputs, and be transparent about its methods and data. This viewpoint considers four models of S&T review and their capacity to respond to the challenge of the life sciences: standing advisory boards; ad hoc working groups; peer review; and wikis. It then identifies a hybrid model that is suitably broad, diverse, and transparent.     

Estimating defence budget saving from disarmament: the United States’ case

Probing the technology in the production of US national defence by using a dynamic cost‐function model with adjustment costs, this paper evaluates the effect of reducing the level of national defence on the defence budget saving. Our inquiry involves estimating the defence production structure without output data for non‐market goods that are normally unavailable. Our findings include: (i) the United States behaves rationally to minimize cost in the production of national defence; (ii) the adjustment costs are larger in disarmament than in military build‐up; (iii) due to the adjustment costs peculiar to disarmament, the defence budget saving from disarmament appears small, but cutbacks allow great savings on the defence budget.     

NUCLEAR PROLIFERATION

As the potential for the involvement of corporations in the manufacture of nuclear weapons has increased, particularly through dual-use technology, global regulation has failed to keep pace. Where regulation of private corporations does exist, in the form of treaties, UN resolutions, or more informal arrangements, the obligations fall only on states. This state of affairs is a result of international law's traditional deference to state sovereignty; yet, it has led to significant shortcomings in the global regulatory regime, where states are unwilling or unable to meet their obligations. While radical departures from the traditional model of international law might remove the regulatory gaps caused by noncompliant states, such changes are unrealistic in the current political climate. More realistic changes must be focused on, offering greater recognition of the role of private corporations in nuclear proliferation and increasing state compliance with existing regulation.

信息化条件下的军备控制

军备控制的目的是维护国家的安全和减少国家安全威胁.随着现代科学技术的发展和世界经济一体化进程的加快,国家安全威胁的因素与国家军事能力同步增长.尤其是现代信息技术的快速渗透和发展,不仅带来了安全隐患的增加,也加速了武器装备的更新换代,对国际军备控制产生了广泛的影响.     

COIN fights: A response to Etzioni

Etzioni both exaggerates and minimizes the influence of my book Learning to Eat Soup with a Knife on different components of US military doctrine, mischaracterizes my treatment of the Malayan Emergency, and unfairly denigrates the successes of counterinsurgency in Iraq from 2007 to 2011 while misattributing the reasons for its failures in both Iraq and Afghanistan.
