In this paper a new contingency screening and ranking method is formed by combiningiterative filtering screening technology with continuation power flow analysis. Researchingpreventive control policy in reactive power compensation and load control when themargin of stability is serious, and reciprocal math model is given;through the exempleof IEEE39 typical system , the availability of the discussed methods in this dissertationwas approved. Aimed at the real grid, the contingency screening analysis and preventivecontrol policy based on Beijing power grid is discussed;the static voltage stabilityanalysis software based on figure draw of Beijing grid is realized, and the software hasthe junction to BPA .

就事故分析提出了几个值得探讨的问题：事故与断口两侧有工频电源有关；雷击波的陡度值处于外绝缘大于内绝缘的区域和电压抽取装置的削波作用不显著而使灭弧室内绝缘击穿；外绝缘先击穿或内、外绝缘同时击穿；事故与雷击进线段发生绕击或反击的关系是主要的还是次要的。

This paper introduces the accident treatment procedures,and analyzes the causes according to one direct crude oil furnace tubes perforated accident.

以一起直接式原油加热炉炉管穿孔事故为例，介绍了事故处理程序，分析了炉管穿孔的原因是由于漏点腐蚀、坑点腐蚀以及炉管管卡损坏导致的，并提出了类似事故防范对策。

As study's starting with soft soil's characters,the questions about the representations and causes of quality accident, judgement and appraisement on existing building, full use of bearing capacity of ground foundation and reinforcing ways applying to the districts of soft soil are analyzed and discussed herein. The aim is to build a suit of mechanism from 'accident representations -- causes analysis-- existing building appraisement of capacity--ground foundation bearing capacity full use' to 'reinforcing ways choice',so that the pertinence is better when the existing building is reinforced.

本文以软土的特性当作为研究的出发点，对既有建筑物的质量事故表现、质量事故原因、原建筑物的鉴定评估、地基基础承载力的充分利用及适用于软土地区的加固方法进行了分析、探讨，其目的在于建立一套从&事故表现----原因分析----原建筑物性能评估----地基基础承载力的充分利用&，到&选择加固方法&的机制，使得在既有建筑物加固时更具针对性。

To reduce the number of accidents involving mopeds and pedestrians, the town council of Balmer Island should limit the number of mopeds rented by each of the island's six moped and bicycle rental companies from 50 per day to 30 per day during the summer season.

1，作者没有提供足够的证据证明减少出租的数量事故就会减少，人们可能会自己购买自行车 2，作者也没有提供任何临近岛屿的情况，可能和 Balmer Island Gazette 完全不同 3，作者还忽略了其它因素：比如，考虑其它能够减少事故的因素是否比限制租车数量更好；此外，Torseau 去年事故的减少是否是因为限制出租的结果(1) T 地的下降不一定和限制出租数量有关。

Results The most vulnerable population were male with age during 21-50 year＇ s old. The main victims of road traffic accidents were passengers, pedestrians, wheelmen and motorcycle-riders.

结果伤亡人员以男性为主，年龄21-50岁；个体户、农民及农民工和交通运输人员是交通事故发生的高危人群；乘车者、行人、自行车和摩托车驾驶员为交通事故的最大受害者；机动车司机的过失是导致事故的最主要原因；损伤部位以头部和多部位伤最多。

In this theme, it is resolved the problem that how to monitor the running status of the semiautomatic grab unloaders The system can discover and forecast the failure in time, avoid the magnitude accidents and enormous economic loss, what is more, we can dig out the hidden troubles from the running status of the equipments and cut down the failure stop time caused by human being.

文章解决了对半自动桥式抓斗卸船机运行状况的监测问题，可以及时发现、预告故障，避免重大事故的发生和巨大的经济损失，而且可以根据卸船机的运行状态找出生产系统中的事故隐患，消除事故隐患，减少由于人为和技术因素引起的故障停机时间。
