我国现行工程建设消防技术标准存在问题及解决对策

工程建设消防技术标准是公安消防机构审核、验收及工程技术人员设计、施工及验收的依据,也是公安消防机构进行日常监督检查和执法的技术依据。然而,目前我国现行工程建设消防技术标准的编制仍存在一些不完善的方面,影响了这些标准的有效执行。在对当前各类工程建设消防技术标准进行分析的基础上,总结了现行工程建设消防技术标准亟待完善的若干方面,并对此提出相关建议。     

Militarism in post-war Cyprus: the development of the ideology of defence

This article provides a theorisation of militarism in post-war Cyprus. Based on qualitative empirical research conducted in Cyprus in 2011, the article explores the manifestation and steadfastness of Greek-Cypriot militarism, and the development of this militarism, which appeared after the partition of the island in 1974. In particular, it proposes the ideology of defence as a way to understand post-war Greek-Cypriot militarism. It shows the embedded nature of defence in the idea of the national struggle. It aims at mapping the character of this militarism in order to provide the grounds for future discussion. Only by understanding the interconnecting discourses that made Greek-Cypriot militarism possible in post-war Cyprus, can we understand its past, present, and future.     

多品种空投小件装载优化建模研究

针对空投小件装载率低下的现状,提出利用相关容重比平衡法,制定装载计划以充分利用飞机的载重能力及其使用面积,分别建立了单机和多机空投小件装载模型。该模型充分考虑了飞机的面积和载重量,对提高空投小件装载的利用率,起到良好应用效果。     

A strategic model for state compliance verification

The theory of directed graphs and noncooperative games is applied to the problem of verification of State compliance to international treaties on arms control, disarmament and nonproliferation of weapons of mass destruction. Hypothetical treaty violations are formulated in terms of illegal acquisition paths for the accumulation of clandestine weapons, weapons‐grade materials or some other military capability. The paths constitute the illegal strategies of a sovereign State in a two‐person inspection game played against a multi‐ or international Inspectorate charged with compliance verification. The effectiveness of existing or postulated verification measures is quantified in terms of the Inspectorate's expected utility at Nash equilibrium. A prototype software implementation of the methodology and a case study are presented. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 260–271, 2016     

朝核问题对中国边境安全的影响

朝核问题一直是困扰东北亚地区安全的核心问题,自20世纪90年代第一次朝核危机至今．朝核问题不但没有得到妥善解决,反而更加复杂。2006年10月9日,朝鲜宣布成功进行了地下核试验,朝鲜半岛再一次成为全球关注的焦点。在前人研究的基础上,就朝核问题产生的背景,朝核问题对中国边境地区经济、地区稳定以及生态环境等方面产生的影响进行分析和探讨。

多芯片焊球阵列封装体受热载荷作用数值模拟

针对典型高密度多芯片BGA(焊球阵列)封装体建立三维有限元分析模型,研究不同尺寸封装体在稳态热载荷作用下的结构变形和应力情况,在此基础上引入包含等效梁和危险焊球真实几何形状和间距等在内的简化模型以进行序列分析,研究各设计参数对力学参量的影响。数值结果反映了封装体应力分布及其变化特点,表明影响封装体变形和应力的主要参数;提出的建模方法简便有效,可以方便地用来分析不同类型的BGA封装,并扩展应用至不同的分析目的,为此种结构的设计和优化提供一定参考。     

The bottleneck problem with minimum quantity commitments

Given an edge‐distance graph of a set of suppliers and clients, the bottleneck problem is to assign each client to a selected supplier minimizing their maximum distance. We introduce minimum quantity commitments to balance workloads of suppliers, provide the best possible approximation algorithm, and study its generalizations and specializations. © 2005 Wiley Periodicals, Inc.
