Science china(Technological Sciences) 2010年第10期53卷 2739-2747页

Fire simulations and sensors are widely used in building fires,various data such as temperature,co.and co. co.centration,visibility can be obtained by sensors and sensor-based simulation. It is important to generate a risk map based on such data so that we can use it to estimate safety of the building. In this paper,we propose a method to generate a dynamical,integrated risk map using sensor readings in a building fire. Such risk evaluation model is developed using similarity co.parison between the space state and dangerous state by a likelihood distance calculating and data grouping from a two-step cluster method. The risk evaluation model co.siders the integrated influence on the occupants in the zone from high temperature,lack of oxygen,toxic and harmful gases and shows the relative fire risk map at certain time. Based on the simulation study,it is proved that multi-factor fire risk analysis would be more objective and accurate than single factor and two-factor risk analysis and the fire risk evaluation model can generate a risk map and provide the classification information and the whole building risk statistic results to support evacuation co.mand and co.trol.

Journal of Materials Science & Technology 2001年第6期17卷 643-645页

With the progress of ULSI technology, materials with low dielectric co.stant are required to replace SiO2 film as the interlayer to scale down the interco.nection delay. Fluorinated Si oxide thin films (SiOF) are a promising material for the low dielectric co.stant and the process co.patibility in existing technology. However, SiOF films are liable to absorb moisture when exposed to air. By treating the SiOF films with O-2 plasma, it was found that the moisture resistibility of SiOF films was remarkably improved. The mechanism of the improvement in stability of dielectric co.stant was investigated. The results show that: 1) F atoms dissociated from the films and the bond angle of Si-O-Si decreased. 2) The plasma treatment enhanced the strength of Si-F bonds by removing unstable =SiF2 structures in the films. Resistibility of SiOF films in moisture was improved.

Treated FeS2 samples were prepared by natural FeS2 samples which were ground first, heated in nitrogen and then washed in acid. The levels of impurity elements, primarily present as metallic oxides and sulfides, are higher in the natural FeS2 than those in the treated sample. Scanning electron microsco.y shows that the grain sizes of treated FeS2, particles are smaller than those of natural FeS2 particles. The electrochemical performance of Li/treated FeS2 cells is attributed to the smaller grain sizes and higher purity of treated FeS2 particles in co.parison to the natural FeS2 sample.

贵州坝陵河大桥为主跨1088m的单跨简支钢桁加劲梁悬索桥,钢桁加劲梁的主桁架采用整体节点连接。为研究该桥主桁架整体节点的传力机理及疲劳性能,对上弦杆整体节点1∶1.4缩尺模型进行疲劳试验。根据该桥设计交通量,采用BS5400规范中的标准疲劳车,按损伤等效原则,并考虑多车效应及缩尺比例,推算试验疲劳荷载。试验结果表明,经过200万次的循环加载后,节点模型未出现任何疲劳裂纹,应力状态稳定,结构疲劳性能满足设计要求。该整体节点形式对我国今后大跨钢桁梁桥类似节点的设计和研究有重要参考意义。
