某型舰炮方向机蜗轮蜗杆箱改进研究

分析了某型舰炮方向机蜗轮蜗杆箱的失效原因,提出了采用以缓冲机构为主体的改进方案,在对原机构不作大改动的条件下,提高了该机构的承载能力和使用寿命,改善了受力条件和工作条件,并易于生产和推广应用。     

用时序展开法求解瞬时无耗传输线方程

本文用时序展开法直接在时域中求解了任意终端和输入端时无耗时变传输线方程。给出了这个问题的一般解。此方法简单,结果的物理意义明确,对分析准行波系统的时域问题具有一定的参考价值。     

强脉冲 CO2 激光与靶的相互作用

在真空背景下的实验表明,当微秒量级的强脉冲激光与靶材相互作用时,由于靶材的升华,激光维持爆震波依然存在。爆震波产生的压缩波传入靶内,该应力波的作用是材料破坏的重要因素。而强脉冲激光引起的汽化反冲压力、热应力和烧蚀破坏也是不可忽视的因素。实验还表明,在真空背景下维持爆震波足以将后续激光屏蔽。     

《论语》的“知”论探微

《论语》中的“知”是一种知识、才智、智慧,也是一种认知方式。它的内容广泛,可粗分为“闻见之知”和“德性之知”,“知”来源于“生而知之”和“学而知之”。孔子主张通过多见、多闻、多习、多行等方式“学而知之”。“知”是为了获取一种“智”的生命智慧,为了培养一种“仁智”双修的理想人格。     

苏共思想教育工作失策对我军的启示

苏联剧变,有其多方面的原因。就意识形态来说,苏共思想教育工作的失策,导致全社会尤其是青年一代从意识形态迷茫,滑落到理想信念崩溃,无疑是政变的思想根源。分析苏共思想教育工作的经验教训,以便创新和改进我军思想政治教育的内容、形式和手段,促进思想政治教育工作的有效开展。     

浅析炮车比

本文以坦克发射时车体的角振幅和乘员所受加速度不超过一定值为基础,推导了炮车比极限值的理论公式;并对影响炮车比极值的因素进行了分析,最后,以59式坦克为例得出炮车比不超过1.71,该结论具有普遍意义.     

From rivals to partners: AirSea Battle and the US air force–navy relationship

AirSea Battle (ASB) has generated significant publicity, controversy, and debate among scholars, analysts, commentators, and observers of US defense strategy. However, a research gap exists concerning formal analysis of the impact of the operational concept on the relationship between the US Air Force (USAF) and the US Navy (USN). The impact of the ASB operational concept on the USAF–USN relationship is examined across the issue areas of strategy, budgets, weapons procurement, and training. These four issue areas represent important areas of historical conflict and competition between the Air Force and Navy. The conclusion is that ASB is ushering in a new era of Air Force–Navy partnership that advances the inter-service dynamic from “jointness” toward integration. The emergent USAF–USN partnership therefore represents a significant development in US defense politics and defense strategy.     

Epidemics,national security,and US immigration policy

What are relationships between epidemics, national security, and US immigration policy? This question is important because it sheds light on transnational or nontraditional security areas, American immigration policy, and a pressing issue for US leaders who have recently faced epidemics such as the West Africa Ebola outbreak that began in 2013. This article answers it and lays ground in the area by reviewing epidemics in world history, using International Relations and Security Studies works to specify dangers of contagions for states, and identifying three general immigration measures that American leaders have utilized from the seventeenth century to the present day to protect against contagions, which are (1) policies restricting entrance of foreigners thought to carry specified diseases, (2) the isolation or quarantining of immigrants with contagious disease, and (3) delegating the President with authority to stop immigration in the event of an epidemic abroad. This study has implications for research and contemporary US immigration policy.     

Expanding the Dragon’s Reach:The Rise of China’s Anti-access Naval Doctrine and Forces

Among the multiple dimensions of the tous azimuths modernisation of Chinese naval forces, the development of China’s anti-access capacity has recently elicited considerable interest. The important link between this capacity and an overarching vision of the use of force – i.e. a naval doctrine – has, however, often been left implicit. This article shows that the particular development of China’s naval anti-access forces – more precisely, forces with an impact on the naval balance – can be explained by a shift of China’s naval doctrine towards a distinctly pre-emptive posture, which, itself, stems from the set of constraints imposed by the framework of ‘local war under informationised conditions’.     

Japan’s Emerging Trajectory as a ‘Cyber Power’: From Securitization to Militarization of Cyberspace

Japan has been overlooked as a ‘cyber power’ but it now becoming a serious player in this new strategic domain. Japanese policy-makers have forged a consensus to move cybersecurity to the very core of national security policy, to create more centralized frameworks for cybersecurity, and for Japan’s military institutions to build dynamic cyberdefense capabilities. Japan’s stance has moved rapidly toward the securitization and now militarization of responses to cyber challenges. Japan’s cybersecurity stance has bolstered US–Japan alliance responses to securing all dimensions of the ‘global commons’ and extended its defense perimeter to further deter but potentially raise tensions with China.
