南部非洲地区警官合作组织

南部非洲地区警官合作组织是为了遏制犯罪而建立的地区性警务合作组织。由于它重视联合行动并且获得了成员国政府的支持及国际刑警组织的协助 ,因此 ,在打击该地区犯罪方面发挥了积极作用。

2005／06年度南部非洲谷物进口量将大幅增加

在南部非洲，2005年主季作物的收获工作接近尾声。尽管由于该次区域最大生产国南非取得了1994年以来的最高产量，因此估计该次区域谷物总产较高，但若干已经减产（图i）。该次区域受降雨失常和长期干旱的影响，特别是在某些农区玉米生长的关键时期，造成单产大幅下降。今年4—5月间，粮农组织，世界粮食计划署作物和粮食供应评估团走访了马拉维、莫桑比克、津巴布韦、莱索托和斯威士兰。粮农组织的早期产量估计显示，赞比亚、马拉维和、

基于经济性的南部非洲高温地区沥青路面改进与维修策略研究

南部非洲高温地区的沥青路面经常面临着车辙损伤、龟裂和水毁等问题,这不仅影响了道路的通行质量,也增加了道路维修的成本。因此,本文通过对提高南部非洲高温地区沥青路面抗车辙能力的资料进行研究,探讨了经济性的改进和维修策略,以便于提高路面使用寿命,降低维修成本,同时也为其他相关理论研究人员提供一定的参考价值。

A Steady-State Contingency Analysis of the SADC Regional Grid Using the N-1 Criterion

Southern Africa has experienced electric power deficits over the last decade. This has been due in part to the member countries＇ inadequate electrical power supply system, as well as load growth in areas which were not adequately planned for. This has induced the formation of organizations such as SADC （Southern African Development Community） and SAPP （Southern African Power Pool） that have the common goal of achieving development and economic growth in the region which comprises of 15 member countries. This paper presents results from a security analysis of the region＇s electric power supply system using a baseline level of performance. This was carried out by performing a steady-state contingency analysis on a SADC power network model subject to the N-1 criteria which expresses the ability of the power network to experience a contingency without causing an overload or failure in any other part of the network. Simulations were carried out using DigSilent.
