The subversive nature of information war lies not only in the information itself, but also in the circulation and application of information. It has always been a challenge to quantitatively analyze the function and effect of information flow through command, control, communications, computer, kill, intelligence,surveillance, reconnaissance (C4KISR) system. In this work, we propose a framework of force of information influence and the methods for calculating the force of information influence between C4KISR nodes of sensing, intelligence processing,decision making and fire attack. Specifically, the basic concept of force of information influence between nodes in C4KISR system is formally proposed and its mathematical definition is provided. Then, based on the information entropy theory, the model of force of information influence between C4KISR system nodes is constructed. Finally, the simulation experiments have been performed under an air defense and attack scenario. The experimental results show that, with the proposed force of information influence framework, we can effectively evaluate the contribution of information circulation through different C4KISR system nodes to the corresponding tasks. Our framework of force of information influence can also serve as an effective tool for the design and dynamic reconfiguration of C4KISR system architecture.

鼠疫是由鼠疫耶尔森菌感染导致的动物源性传染病,也是我国法定报告甲类传染病和国际检疫传染病。在人类历史上曾经发生过3次世界大流行,当前除南极洲和大洋洲外,各大陆均存在鼠疫自然疫源地。马达加斯加和刚果(金)是目前世界上人间鼠疫流行水平最高的地区。在20世纪中期,我国人间鼠疫流行,1950—1954年平均年报告1400.8例;1955年后,我国人间鼠疫的大规模暴发得到有效控制,1955—1999年平均年报告24.7例。2000年至今,我国人间鼠疫病例仍未销声匿迹,期间累计报告514例。基于One Health理念的鼠疫控制策略是一种更优解,主要体现为“生态学动物监测”+“人间早期诊断处置”的双重手段。有效的动物监测,对鼠疫波及人间可进行准确预测,做到早期预警;而对人间鼠疫病例进行早期诊断早期处置,在一方面可以有效控制人间疫情扩散,另一方面也能有效降低病死率。

NiTi形状记忆合金因其优异的弹热效应在新兴固态制冷领域具备广阔的应用前景.然而,该类合金较高的相变临界应力使得其弹热效应需要很高的机械载荷来驱动,对固态制冷器件的小型化和大规模应用带来了挑战.文章通过在NiTi形状记忆合金薄板上引入孔洞,揭示了孔洞体积分数、分布形式对薄板弹热性能的影响.结果表明,孔洞造成的应力集中效应能够在显著降低薄板相变驱动力的同时,有效增加薄板的整体制冷温度和吸热量.薄板在变形过程中的整体力-位移响应和温度演化强烈依赖于孔洞体积分数,孔洞分布形式仅仅影响薄板的局部应力-应变-温度场,而对整体的热-力响应影响较小.进一步地,基于应力对数客观率,在不可逆热力学框架下建立了形状记忆合金有限变形热-力耦合本构模型,并完成了模型的有限元移植.通过与实验结果的对比发现,提出的本构模型能够很好地预测孔洞对NiTi形状记忆合金薄板变形行为和弹热性能的影响,从而为该类合金带孔薄板的设计提供理论工具.
