The application of catastrophe theory in modelling freeway traffic operations.

2危险评价的广义突变理论充分考虑了事故致因的各因素，可实现事故过程的连续动态分析。

Using the accident mechanism of the risk management system, the essence of the energy transfer gradually, combining that the chemical equation can explain the occurrence of chemical reaction process,Chemical equation can explain the mechanism of a safety management system.

利用事故发生机理——管理系统的危险能量逐级传递的本质，与化学表达式能够准确形象的表达化学反应过程的特性相结合，用化学表达式解释安全管理系统事故的发生机理。

Through analysis of the explosion peculiarity, sort, risk assessment index of explosive and exploder, and impact of blast as well, the difficulties during operation are present.

通过分析爆炸特性、分类和爆炸物质危险特性，以及爆炸的危害作用，指出了爆炸灾害事故处置的难点问题，对处置爆炸灾害事故需要的专业理论、应掌握的技战术要点、心理训练和灭火救援准备进行了阐述。

By qualitative analysising, all lateen dangerous factors of VCM spheroid fired blast ed accident are identificated and the dangerous grades are definited.

通过定性分析，辨识了VCM球罐发生火灾、爆炸事故的潜在危险因素，确定了相应的危险等级，然后以"VCM储罐火灾、爆炸"为顶事件建立了事故树，由布尔代数方程求出了28个二阶最小割集，20个三阶最小割集，并计算出各基本事件的结构重要度系数。

A oil warehouse was served under the backgroud of engneering application in this paper. Based on analyse and distinguish of oilcan fire, hazardous factors in explosion and accidental characteristics, consequently, inherent hazard scale of the oilcan section was educed by using DOW's fire explosive index method. In that way those errors between safety precaution and present criterion were also definited by analysising and calculating the effect of safty compensating coefficient in deducing hazardous scale of oilcan fire.

本论文以某油库作为工程应用背景，在对油库的火灾、爆炸危险因素及事故特点进行分析、辨识的基础上，应用道化学火灾爆炸指数评价法，对油库中最危险的油罐区进行定量评价，得出油罐区的固有危险等级，分析、计算了不同状态下安全补偿系数对降低罐区火灾危险等级的影响，明确了所采用安全措施的有效性及与现行标准规范要求尚存的差距。

Poisson distribution in accident----Opportunity for an event to occur is large, time of event is small.

还有我国道路上经常出现的"事故多发地段，小心驾驶"专类警示牌在美国是不存在的，应为在该路段出了事故之后，受害人可以根据警示牌起诉政府知道该路段为危险路段但是却没有采取相应的措施来改善。

After giving a brief analysis of pressure hazards and accident simulation methods, the authors introduce the system of European PED - EN system for pressure equipment in order to eliminate or reduce pressure hazards by studying 97/23/EC Pressure Equipment Directive and EN13445 Unfired Pressure Vessels and describe the impacts of PED - EN system on the ASME pressure vessel codes and the...

本文在简要分析压力危险以及事故后果模拟方法的基础上，先结合97/23/EC《承压设备指令》、EN13445《非火焰接触压力容器》等规范标准，介绍以消除或降低压力危险为出发点的欧盟承压设备规范标准体系，再介绍美国应对欧盟97/23/EC《承压设备指令》的对策措施，最后提出按压力危险程度确定承压设备的范畴、以标准应满足法规要求的理念建立承压设备法规标准体系、开展承压设备基本安全要求研究、研究承压设备最新规范标准和我国应对策略、成立中国承压设备研究委员会等建议。
