在役立式钢制油罐底圈罐壁可靠性分析   总被引:2,自引:0,他引:2  
在役油罐的安全评估通常采用经验评估法,具有较大的盲目性。立式钢油罐强度破坏的重点区域在底圈罐壁,其作用的各变量因素具有较大的随机性,可靠性评价方法较为适用。根据结构可靠性理论推导出底圈罐壁强度失效的计算模型,并进行实例计算分析,为在役油罐的安全评估提供了一种量化的评价方法,具有一定的指导意义和参考价值。  相似文献

This article is a response to Evron's argument, offering readers another perspective to assess China's military modernization and war fighting capabilities, using the same framework and methodology. It examines three topics: China's national security and military strategy, the PLA's procurement decision-making process, and China's military support and mobilization system. It concludes that, China's military modernization is to fight and win local wars under the conditions of informatization, but if required the PLA can reliably supply large numbers of sophisticated weapons and spare parts, to wage a complex and prolonged conflict.  相似文献

This article proposes a case study of the multinational counterinsurgency operations that occurred in China during the Boxer Rebellion in 1900–1, to provide a better understanding of the political and military dynamics specific to this type of mission. The study focuses primarily on the nature of the cooperation on the ground, the various national approaches to counterinsurgency, and the asymmetry of strategic approach between the Westerners and the Chinese. A discussion is also proposed, highlighting that combined counterinsurgency is not per se an obstacle to the unity of command, but that politically international coalitions create unique challenges to counterinsurgency operations.  相似文献

ABSTRACT

The United States and China are testing boost-glide weapons, long-range strike systems capable of flying at Mach 5 or faster through the upper atmosphere. For the United States, these systems would provide a conventional prompt global strike capability, which, together with US ballistic missile defense programs, Chinese experts regard as a threat to China's ability to conduct nuclear retaliation. This perception is encouraging the Chinese military to modify its nuclear posture in ways that tend to create greater risks for both sides. If China's own boost-glide systems are meant to carry nuclear payloads only, their deployment would not fundamentally alter the current situation between the two states. However, if they were conventionally armed or dual-purpose, or if the United States could not determine the payloads they carried, the deployment of Chinese boost-glide systems could compound problems of strategic stability created by the introduction of ballistic missile defense, antisatellite, and antiship ballistic missile capabilities. If the technical hurdles can be overcome, it may be difficult for the two sides to refrain from these deployments in the absence of strong mutual trust or an established arms-control relationship. New confidence-building measures and expanded mutual transparency are warranted to avoid creating new dangers.  相似文献

This essay explores the obligations arising from the United Nations Convention against Transnational Organised Crime, signed in Palermo, Italy at the end of 2000. It also discusses the initiatives required to prepare the legal system and related infrastructure of Zimbabwe for its implementation. Zimbabwe joined more than 120 other countries in signing the Palermo convention, but has not yet ratified it. The ratification would enshrine the latest initiatives to develop effective strategies against transnational organised crime. The Palermo convention makes demands on the laws and institutions of states parties which could enhance their capacity to confront organised crime. Ratification signifies competence to implement the prescribed obligations, which can only occur after introducing suitable domestic laws, and adopting the necessary administrative mechanisms. The required reforms are bound to have certain policy and legislative implications for Zimbabwe. Regional initiatives complementary to the Palermo convention are expected to catalyse positive changes in Zimbabwe's response mechanisms.  相似文献

President Barack Obama has pledged to secure the ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which was previously rejected by the U.S. Senate in 1999. This article attempts to predict the potential implications of Washington's ratification for the treaty's future by analyzing the positions and options of the eight other essential holdouts. The authors conclude that without the United States to hide behind, facing domestic and international constraints, and lacking substantial strategic reasons to remain outside the treaty, most holdouts will move toward ratification. Nonetheless, the process is likely to be time consuming, and several of the key actors remain unpredictable.  相似文献

This paper re-examines the long-run causal relationship between military expenditure and economic growth in China over the period 1952–2010. An empirical econometric analysis based on a Barro-style growth model is conducted. By employing the Bartlett corrected trace test, which provides better approximations of the finite sample distribution to determine the rank of cointegration, the results support the existence of a single long-run equilibrium relationship between the variables. Furthermore, it is confirmed that the cumulated shocks of military expenditure primarily originate from different components of shocks that relate to economic development rather than the other way round.  相似文献

There are conflicting views as to the relationship between a nation’s defense expenditure (DE) and its population’s income inequality (INEQ). DE, always an important part of government budget, can easily crowd out transfer payments, necessary to improve INEQ; however, these payments may also create a demand that may raise the income levels of the lower income earners. Consequently, the relationship between DE and INEQ is an important question. This paper examines the relationship between DE and INEQ in China for the period of 1989–2012. Utilizing basic cointegration and causality tests, our objective is to add to the literature by providing evidence that China’s DE, in fact, do have an impact on INEQ.  相似文献

The contest-theoretic literature on the attack and defense of networks of targets focuses primarily on pure-strategy Nash equilibria. Hausken's 2008 European Journal of Operational Research article typifies this approach, and many of the models in this literature either build upon this model or utilize similar techniques. We show that Hausken's characterization of Nash equilibrium is invalid for much of the parameter space examined and provides necessary conditions for his solution to hold. The complete characterization of mixed-strategy equilibria remains an open problem, although there exist solutions in the literature for special prominent cases.  相似文献
