新型气泡雾化细水雾灭火系统的研制与开发

将气泡雾化技术引入到消防领域，研制并开发了一套新型细水雾灭火系统，着重设计和制作了系统的关键部件——气泡雾化喷头。该系统具有工作压力低、雾化流量小、不易堵塞以及安全可靠等优点。在此基础上，利用所研制的气泡雾化细水雾系统进行了汽油火的实体灭火实验，灭火效果良好。     

Are police deaths a consequence of flaws in the South African Police Service administration? A SWOT analysis

This article argues that since the advent of democracy, the South African Police Service (SAPS) has been plagued by poor administration. Having inherited a repressive police force, the post-apartheid national police commissioners (NPCs) have found it difficult to transform the organisation. Among the unintended consequences has been a rise in police deaths. Although police deaths can be attributed to numerous factors, this article focuses on fault lines in the SAPS administration through a strengths, weaknesses, opportunities and threats (SWOT) analysis drawing largely on existing scholarly debates. Essential theoretical perspectives have been employed to gain insight into the root causes of the problem. The article concludes that poor administration and a lack of trust, partnership and collaboration between police officers and community members have perpetuated the killing of police officers. These killings are further compounded by the flawed and ill-conceived selection and appointment of NPCs. As a consequence, the article recommends that the appointment of NPCs should be promptly reviewed. It further recommends that each potential candidate should have risen through the ranks and must fully comprehend the challenges facing the organisation.     

水雷总体的声学问题

提出了水雷隐身的总体声学问题概念.通过对水雷声隐身的两种手段:壳体上涂涂层和改变外形进行比较,发现隐身的关键在于外形设计.讨论了改变水雷外形以降低其目标强度(TS)途径,分析了几种不同水雷外形对声纳探测距离的影响,认为改变水雷外形是降低声探测距离的有效手段.
