鹤管气阻与泵汽蚀分析

鹤管气阻与泵汽蚀所指的对象不同,但两者具有相同的物理意义,都是指当液体介质的绝对压力小于其实时饱和蒸气压时所体现的物理现象。阐述了鹤管气阻的原因及目前解决的措施,分析了离心泵汽蚀方程的物理意义。根据能量平衡方程,推导出吸入系统管道不发生气阻的安装高度方程,并与泵不发生汽蚀的安装高度方程进行了对比分析。最后得出结论,要保证离心泵正常工作,必须同时满足吸入系统工艺管道安装高度要求以及泵安装高度要求。     

香港建筑能耗现状特征分析

随着经济的发展,香港的建筑行业也迅速发展。建筑面积的持续增长,在改善人们居住条件的同时也导致了建筑能耗的大量攀升。为了实现香港经济的可持续发展,有必要对香港地区建筑能耗现状进行研究。介绍了香港建筑的发展,在此基础上详细介绍了香港地区建筑能耗的历史发展趋势,并对建筑能耗的类别进行了详细的分类及分析。通过分析可看出建筑能耗在香港地区能源消费中占有重要的地位,为了社会的可持续发展,建筑节能势在必行,因此本文也对香港地区建筑节能的现状和节能潜力进行了分析。

Expeditionary police advising: some causes of failure

ABSTRACT

The practice of dispatching teams of police advisors to other states to build or train foreign security forces began at the end of the nineteenth century, yet there exists no definitive history of the practice, or any definitive theoretical approach underpinning why such missions succeed or fail. Drawing upon their recent edited book on expeditionary police advising, and by examining the donor or sending states, the host nations, and the use of police in counterinsurgency situations, the authors present some key reasons why such missions fail, and lay some groundwork for additional study of this important subject.     

Building the next nuclear community

This viewpoint takes stock of the changes in the strategic nuclear landscape in recent decades and reflects on its consequences on the policy community. It finds that the number and scope of issues have expanded considerably; they have manifested themselves in many more regions of the world; and they have become deeply politicized and polarized. The consequences have been twofold: the nuclear policy field has seen the development of an increasingly diverse expert community composed of highly specialized functionalists and regionalists, and it has become ever more divided into two entirely separate ideological camps—one that believes in deterrence, the other in disarmament. The stove-piping of expertise and the widening gap between deterrence and disarmament ideologies are immensely problematic because, in different ways, they stand in the way of the emergence of a better and safer nuclear future. Looking ahead, it is critical to “bust the silos of expertise” and to build bridges between the deterrence and disarmament ideological camps. Only such a community-building effort will help solve today’s and tomorrow’s nuclear challenges.
