针对钢质油罐底板腐蚀,首先分析了油罐底板腐蚀工程检测数据的特点和腐蚀试验数据统计分析理论;然后针对工程检测信息不完全的特性,以最大腐蚀深度的预测估计为目标,建立了以轻微腐蚀面积估计来实现腐蚀概率修正估计的模型;最后利用广州等地27个罐约900条检测数据估计了油罐底板的最大腐蚀深度。其最大相对误差小于45%,约80%的相对误差优于30%。 相似文献

Asia, where nuclear powers already interact (including North Korea), exerts a growing influence on the thinking and policy underlying Russia's current and future nuclear (and overall defense) posture. China's rise is forcing Russia into a greater reliance on strategic offensive weapons and tactical nuclear weapons. These in turn will reinforce its opposition to US missile defenses, not only in Europe but also in Asia. Russia must now entertain the possibility of nuclear use in regional conflicts that would otherwise remain purely conventional. It cannot be postulated blindly that nuclear weapons serve no discernible purpose other than to deter nuclear attacks by other nuclear powers. The strategic equation in Asia and in the Russian Far East convincingly demonstrates the falsity of this approach. Nuclear weapons will be the essential component of Russia's regional defense policy if not of its overall policies – and this also includes contingencies in Europe. 相似文献

This article analyses the doctrine development of the People’s Liberation Army (PLA) coping with the Soviet military threat between 1969 and 1989. In the 1970s, the PLA applied a doctrine of ‘active defence and luring the enemy into depth’ based on its traditional operational art. In 1980, the PLA decided to focus its doctrine on positional defence. In 1986, the PLA introduced ‘integrated operations and prioritised strike’, a generalised doctrine that originated from its war history. Many organisational and intellectual challenges in peacetime doctrine development contributed to the PLA’s operational idealism, including its aging leadership, command structure, attitude towards its previous experience, limited analysis of contemporary military developments, and failure in test and validation of doctrines. In the post-Cold War decade, many of these challenges persisted in spite of military modernization efforts. The ongoing military reform has to address these challenges and improve the PLA doctrine development in peacetime. 相似文献

The use of commercial business management techniques is widespread in all government departments, including the Ministry of Defence. This article examines the use of popular management techniques in the Armed Forces and argues that their application is misplaced. It looks at what the “effs” – “efficiency” and “effectiveness” – mean in the business world and to the Armed Forces. It compares the definitions both in business and the Armed Forces and finds that there are few, if any, situations where the same measurements can be applied. Whilst many management techniques are suited for business, the function of the Armed Forces and its output cannot be measured in the same way, complicated by the different metrics of “efficiency” in peace and in war. This difference may not be clearly understood by some politicians, or indeed by some senior military personnel. Using examples from some of the most popular management techniques such as “Lean” and “Agile” it is possible to see that their use might actually diminish the capabilities of the Armed Forces when it comes to performing their principal role – the use of force to achieve political objectives. 相似文献

The existing guidelines for security sector reform (SSR) tend to draw on theoretical work in the field of civil–military relations, which in turn has been derived from Western, liberal democratic models of governance. Although guidelines strongly advise that local culture and context need to be considered when drawing up objectives for post-conflict SSR programmes, this is not often reflected in practice. This article considers some of the reasons for this, citing both in-country challenges and donor-related issues, and suggests that one of the biggest problems is a lack of alternative, non-orthodox models of civil–military relations to draw upon. It is further suggested that elements of suitable alternative models may be found in states which possess political structures not entirely dissimilar to the Western, liberal democratic ideal, but which can offer different perspectives. Detailed research of these structures should produce a pool of sub-models which could then be employed to create bespoke, culturally appropriate objectives for use in post-conflict SSR programmes. 相似文献
