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.     

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.     

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.     

Investigation of the shock compression behaviors of Al/PTFE composites with experimental and a 3D mesoscale-model

The responses of AI/PTFE reactive materials (RMs) under shock compression were investigated by a single-stage gas gun.A 3D mesoscale-model was established based on micro-computed tomography(micro-CT) slice images and confirmed with experimental results.In the high-pressure stage,the com-posites reacted partially,whereas there were no deviations between the partially reacted Hugoniot and the inert simulation results.The simulation reveals that the Teflon matrix melting on the high shock pressure.Melts and decomposition of the PTFE accelerated the diffusion of the atoms.Thus,the reactions of the Al/PrFE composites are more like a combustion rather than a detonation.     

基于信息论的C3I系统决策性能的评价

信息熵是描述信息系统的一种比较成功的方法.采用信息论的方法对决策系统进行描述,在考虑了决策者的有界合理性限制和达到满意性能指标的要求下,分析了单人指挥决策系统的系统性能,并在此基础上分析了多人指挥决策系统的系统性能,最后得出采用决策系统的误差概率P和相互一致性度量Q作为评价C3I系统决策性能标准的结论.
