城市燃气管道喷射火事故后果分析

高压下的城市燃气如果泄露，气体在裂口处被点燃则形成喷射火，对管道周围人员和财产安全造成极大威胁。本文运用喷射火焰对目标的入射热辐射强度计算模型，给出了火灾伤害半径和伤害面积，进而根据城市街区平均人员密度和平均财产密度确定喷射火事故造成的人员伤亡数量和财产损失程度，为城市燃气管道风险评价提供重要的依据。

The rescue,conservation, and restoration of heritage sites in the ethnic minority areas ravaged by the Wenchuan earthquake

Stockaded villages of the Qiang nationality that are made up of watchtowers and watch-houses are an important part of its cultural heritage. The earliest documentary records of its blockhouse-styled construction can be found in Biography of the Ethnic Minority Groups in Southwest China of History of Eastern Han. In 2006, watchtowers and stockaded villages of the Qiang nationality was placed in the preparatory declaration list of world cultural heritage in China and became a minority architectural heritage that is of potential value for world cultural heritage. The Wenchuan earthquake, which happened on May 12th, 2008, caused severe damage to settlements of the Qiangs in the upper reaches of Min River, including the “Tangping Qiang village,” which plays a prominent role in Qiang stockaded villages. In conserving this important architectural heritage, we observe the idea “everything for heritage value”. We discuss and draw up a series of salvage conservation countermeasures and research for antiseimatic key technology during post-earthquake reconstruction period of Tibetan and Qiang settlement engineering projects, including six engineering principles on priority of structure rescue, heritage value, former address maintenance, traditional way of use, protection against and mitigation of earthquake disasters, and spot cleaning and separating. We draw up three rules in engineering strategy, namely: (1) we should follow ultimate orientation of heritage value protection in rescue, maintenance, and protection engineering; (2) degrees of priority of engineering measures should be differentiated according to the situation of the disaster and residential situations of stockaded villages and; (3) we should keep local smiths and conventional art as the base, and modern technology as a supplement in rescue, maintenance, and protection engineering.

咖啡壶的失效评估

本文对某型咖啡壶样品进行了分解和剖析,对各元、器件的特性、工作原理与过程进行了研究.通过工作试验、模拟试验,对整个系统的工作流程进行了实测;在预制失效的情况下,对系统的应激反应进行了监测;根据元件的材料、结构特点和使用环境等因素对其失效模式进行了分析.在以上工作的基础上,采用预先危险分析、失效模式与效果分析和故障树分析等可靠性分析手段,对咖啡壶系统进行了失效评估.评估结果表明,咖啡壶在结构、系统、安全防护设计等方面较为合理,咖啡壶在意外发生时安全保护系统较为完善,符合安全设计准则;咖啡壶金属制弹簧类元件普遍存在抗腐蚀性能差的问题,电阻保持架的加工质量存在问题.     

Explosion risks during the confined storage of bituminous coals : Calculation of gaseous hydrogen accumulation in ship holds

Bituminous coal piles stored in the open air can undergo autocatalytic heating accompanied by the emission of small but appreciable amounts of molecular hydrogen. When the coal is contained in a confined space and the temperature reaches 40°C, accumulation of hydrogen is expected. This process has been observed for a wide variety of bituminous coals. The amount of hydrogen gas expected to accumulate in the air pocket above the coal cargo in ship holds (assuming that the coal's temperature approaches 40°C during the voyage) has been calculated. The results clearly indicate that in most cases the hydrogen concentration will be appreciably above the lower explosion limit in air. Hence when bituminous coals are stored in a confined space (e.g. a ship hold), the explosive risk of hydrogen should be taken into account.
