汽油与柴油混合用作柴油机应急燃料的探讨

应急燃料对于提高战时油料保障能力具有重要意义。文章以在-10#军用柴油中掺入90#车用汽油(简称为汽柴混合油)为例,从柴油机燃料应具有的品质性能着手,分析了汽柴混合油作为柴油机应急燃料的可行性。把车用汽油和军用柴油按照不同的比例掺兑,将试验结果与军用柴油的性能要求和美军应急使用指标对某些理化性能的要求相比照, 指出了汽柴混合油作为柴油机燃料的可行性,并提出了建议。

Neo-conservation

Africa's wildlife is in danger. The last couple of years have been disastrous for the African elephant as poaching for ivory reached record numbers. Rhinos have been hit hard with several sub-species becoming extinct. The current anti-poaching and anti-trafficking operations lack the sophistication and determination that is found abundantly within criminal organisations immersed in this illicit trade. Terrorism, rebellious elements and corrupt officials all benefit from the destruction of Africa's eco-system and the inaction or lack of efficient action thereof by law enforcement officials. This commentary suggests new courses of action using methods from the fields of counter-terrorism and special operations.     

UNITED NATIONS SECURITY COUNCIL REFORM

Much has changed since the United Nations was established in 1945. New challenges confront the organization including global warming, global diseases and global terrorism. Responding to these challenges requires continual change, adaptation and learning—a hallmark of the stewardship of current UN Secretary General Kofi Annan. In 1997 Annan announced major structural changes to streamline the organization, follow up five years later by another initiative to clarify, simplify and rationalize the organization and subsequent efforts to streamline UN peacekeeping. The UN has also forged new partnerships with civil society and the private sector. Important as these changes are, reform of the General Assembly and the Security Council hold the organization hostage to the vested interests of key member states. There are a number of options to make the Council more representative including regionalism, population distribution, economic weight, culture/religion/civilization and democracy. Clearly the largest challenge is the absence of representation for Asia, Africa and Latin America. Currently Germany, Japan, India and Brazil have strong claims—plus at least one candidate from Africa. Should these four countries decide to act in unison, they could force reform of the Security Council     

The inherent propensity toward peace or war embodied in weaponry

Thomas Schelling argues that armed adversaries face an inherent propensity toward peace or war embodied in their weaponry, geography and military organizations. Inherent propensity is the idea that there are characteristics embodied in the weapons that push adversaries toward peace or war, independent of the goals of the decision‐makers, the political disagreement between adversaries, and misperceptions about mutual resolve and hostility. We theoretically illustrate inherent propensity in conventional and nuclear arms settings using Lanchester and Intriligator war models. Our work extends the Intriligator‐Brito model, identifies when the competing Richardson and Intriligator‐Brito views of the relationship between arms races and war are correct, illustrates the stabilizing/destabilizing effects of alliances, and highlights the importance of arms quality control in the US‐USSR relationship.     

钢质油罐底板腐蚀概率估计

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%。     

The practice and theory of British counterinsurgency: the histories of the atrocities at the Palestinian villages of al-Bassa and Halhul, 1938–1939

This article details two largely unreported atrocities by British forces operating against Arab rebels during the Arab revolt, 1936–9, at the Palestinian villages of al-Bassa and Halhul. It then examines the military-legal system that underpinned and authorised British military forces operating in aid of the civil power, suggesting that the law in place at the time allowed for a level of reprisals and punitive actions, such as happened at al-Bassa and Halhul. The article does not conclude that the law allowed for atrocities but it does argue that it gave a basic form and understanding to an operational method that was brutal and could lead to atrocities. It thus tests the idea in much of the literature on counterinsurgency that the British were restrained and used minimum force when compared to other colonial and neo-colonial powers fighting insurgents.     

The virtual dimension of contemporary insurgency and counterinsurgency

This paper looks at the virtual dimension of contemporary insurgency and counterinsurgency. It argues that the West is faltering in the ‘War of Ideas’ with global Jihad for the main reason that the messages that we wish to convey lack narrative coherence. This is a result of the fact that we misapprehend the nature of the virtual operational environment whereas our opponents possess an intuitive grasp of it as a result of which their structure and method of operations are better adapted and more effective than our own. There is no reason, beyond inertia, that this should remain the case.
