浅析军事医学语言的现实意义

军事医学语言是军事语言学的一个分支学科。古今中外的军事医学实践表明,军事医学语言在医学工作中发挥着重要作用,有时对医疗效果起着决定性作用。我国古代十分重视运用军事医学语言保障部队提高医疗效果的作用。但是,军事医学语言学科还不成体系,严重影响着军事医学工作科学效能的发挥。加快军事医学语言学科体系建设,已经成为当前巩固和提高部队战斗力中一个不可忽视的课题。     

军事指挥类期刊对军事学术研究的透视

军事指挥类期刊主要依靠各级军事指挥员,服务于部队全面建设。在军事学术研究队伍不断发展壮大的今天,军事指挥类期刊为部队“能打仗、打胜仗”军事理论研究服务,但军事学术研究存在着研究群体优势和合成作战理论优势发挥不够的问题。因而,要高度重视军事学术研究人才培养,加大经费投入,强化军兵种之间合成作战理论研究的力度。     

含脉冲负载的综合电力系统储能优化配置研究

考虑到舰船环境限制和高能脉冲负载对储能的需求,有必要对储能装置进行合理的选型和优化配置,来提升综合电力系统性能。为此,基于带权极小模理想点法和层次分析法,提出了一种储能装置性能评价函数,并以其为优化目标,进行储能装置优化配置。所提出的评价函数充分考虑系统需求和脉冲负载特性,以储能装置体积、质量和经济性作为评价函数主要组成部分,同时考虑功率、能量、电压、荷电状态等约束,建立优化配置模型,并采用差分进化算法进行求解。以高性能锂电池和超级电容器为例,对所提模型进行求解计算,结果表明在所给权重系数下锂电池性能更优,更适用于综合电力系统,并给出了优化配置后的指导方案。     

爆炸成型弹丸贯穿靶板靶后破片空间分布模型

深空撞击载荷对探测小天体内部物质成分和结构特性具有重要意义,因此,在考虑爆炸成型弹丸(explosively formed projectile, EFP)可变截面的特性和区分靶后破片来源的基础上,建立了EFP贯穿靶板靶后破片空间分布模型。在靶板厚度30 mm至70 mm、EFP着靶速度1 650 m/s至1 860 m/s的条件下,该模型可以定量预测靶后破片云中各个破片的速度、质量、数量与空间位置的关系。结果表明,相对速度总是随相对空间位置的增加而呈线性增加,相对质量、相对数量总是随相对空间位置的增加而呈幂函数增加。     

Formation of adiabatic shearing band for high-strength Ti-5553 alloy: A dramatic thermoplastic microstructural evolution

By using split Hopkinson pressure bar, optical microscopy and electronic microscopy, we investigate the influence of initial microstructures on the adiabatic shear behavior of high-strength Ti–5Al–5V–5Mo–3Cr (Ti-5553) alloy with lamellar microstructure and bimodal microstructure. Lamellar alloy tends to form adiabatic shearing band (ASB) at low compression strain, while bimodal alloy is considerably ASB-resistant. Comparing with the initial microstructure of Ti-5553 alloy, we find that the microstructure of the ASB changes dramatically. Adiabatic shear of lamellar Ti-5553 alloy not only results in the formation of recrystallized β nano-grains within the ASB, but also leads to the chemical redistribution of the alloying elements such as Al, V, Cr and Mo. As a result, the alloying elements distribute evenly in the ASB. In contrast, the dramatic adiabatic shear of bimodal alloy might give rise to the complete lamination of the globular primary α grain and the equiaxial prior β grain, which is accompanied by the dynamic recrystallization of α lamellae and β lamellae. As a result, ASB of bimodal alloy is composed of α/β nano-multilayers. Chemical redistribution does not occur in ASB of bimodal alloy. Bimodal Ti-5553 alloy should be a promising candidate for high performance armors with high mass efficiency due to the processes high dynamic flow stress and excellent ASB-resistance.     

Economic Competition and Nuclear Cooperation

The number of bilateral nuclear cooperation agreements surged during the “nuclear renaissance” of the past decade. This proliferation is only partially explained by the prevailing approaches that focus on strategic imperatives. To supplement these explanations, this study draws on neoliberal models of economic competition to posit that bilateral agreement negotiations also exhibit conditions of “uncoordinated interdependence” and maneuvering to gain market share. Case evidence suggests the contours of supplier state bids for civilian assistance are determined at least as much by considerations about economic competition as they are by positive strategic goals. In addition, this study identifies several cases of cooperation where there appears to be little or no strategic motive for export agreements. The study concludes that patterns of economic competition and the influence of peers in defined competitive spaces alter material payoffs and impact policies. It also identifies a surprising role for principled restraint in dampening strategic and economic competition in some dyads.     

The Demand for Military Spending in Egypt

Egypt plays a pivotal role in the security of the Middle East as the doorway to Europe and its military expenditure reflects its involvement in the machinations of such an unstable region, showing considerable variation over the last 40?years. These characteristics make it a particularly interesting case study of the determinants of military spending. This paper specifies and estimates an econometric model of the Egyptian demand for military spending, taking into account important strategic and political factors. Both economic and strategic factors are found to play a role in determining military burden/spending, with clear positive effects of lagged military burden, suggesting some sort of institutional inertia, plus negative output and net exports effects. The strategic effect as a result of the impact of Israel’s military burden is mostly positive and significant, though its impact is reduced when the impact of important strategic events are taken into account. The military spending of Egypt’s allies Jordan and Syria generally seems to have had no effect on Egypt’s spending. These results are consistent over a range of econometric techniques.     

One size does not fit all: personalized incentives in military compensation

A critical element in implementing a compensation scheme including nonmonetary incentives (NMIs) is recognizing that preferences vary widely across Service members. There are at least three sources of variability: across different population classes, across individuals within a population class, and across NMI packages for a particular individual. Surveys across different military communities, ranks, and years of Service show the difficulty of identifying any NMI that has significant value for even 50% of the active duty force. At the same time, approximately 80% of the surveyed Service members expressed a significant positive value for at least one NMI. Therefore, one-size-fits-all incentive packages will not be nearly as effective as more personalized incentive packages. The authors discuss variability in Service member NMI preferences and outline an approach to implementing personalized NMI packages in military compensation through a sealed-bid reverse auction, where Service members select individual NMIs from a “cafeteria-style” menu of options.     

The United States' retreat from the Middle East and pivot to the Far East is likely to intensify

A combination of threat analysis and “subterranean forces” (such as proclivities to fight conventional wars as compared to asymmetric ones) leads the USA to prefer focusing on the threats from China rather than those emanating from the Middle East.
