灭火

As the introduction of synthetical techniques and the development of fully mechanised coal mining working faces to be overlength and high efficient, new demands are engendered.

由于综采技术的引进和综采工作面向超长高效方向的发展，对矿井防灭火工作提出了新的要求。

The system can monitor on line operation state of the boiler system, including overall monitor of the boiler system, major monitor of boiler, run tending monitor, bar figure display and overrange alarm.

故障诊断根据锅炉运行状态监测情况，确定锅炉系统运行中出现的故障征兆，采用深、浅知识相结合的混合诊断推理机制，分析诊断锅炉系统在运行过程中可能出现的各种故障，如炉膛灭火，过热器爆管，省煤器磨损、泄漏，空气预热器积灰、泄漏，锅炉满水、缺水等常见故障。

Two kinds of fireextinguishing facilities,including wet pipe system in the winding corridor and preact system in the basement,are installed in order to meet the needs of various use functions and different fire areas of the Library of Shenyang Architecture and Civil Engineering University.

为了满足沈阳建筑工程学院新校区图书馆的不同使用功能和建筑专业划分防火分区的需要，设置了两种自动喷水灭火系统。

And it is also found that side ejection can enhance the performance of water mist fire protection systems. For spray fire suppression it is found that longer preburn time shortens extinguishing time.

此外研究结果还显示，采用侧喷方式时，系统的灭火性能将大大提高，而较长的预燃时间则有利于细水雾扑灭油雾火。

Pyrotechnically generated aerosol fire extinguishing agent is a kind of new fire extinguishing material with excellent fire suppressing performance.

固体微粒气溶胶灭火剂是一种新型灭火材料，具有良好的抑制火灾的能力。

Inorganic salts produced in combustion of pyrotechnically generating aerosol fire extinguishing agent are strongly hygroscopic and potentially corrosive to metal surfaces in humid circumstances.

针对固体微粒气溶胶灭火剂对金属材料表面产生腐蚀性的问题，在气溶胶发生装置的释放通路中，通过汽化的十八胺对气溶胶固体颗粒进行原位表面包覆，采用扫描电镜和光电子能谱表征了包覆效果，对包覆前后气溶胶粒子的吸湿性和腐蚀性进行测试，结果表明有机包覆层的存在有效抑制了气溶胶颗粒的吸湿，达到了降低灭火气溶胶对铜片腐蚀性的目的

High expansion foam extinguishing system has the features of high output, low water damage, high reburn resistance, and low cost, it extinguishes class A and class B fire by fully flooding and covering, and it is efficient in controlling floating fire by liquefied petroleum gas and liquefied natural gas.

高倍数泡沫灭火系统具有发泡倍数高、水渍损失小、抗复燃能力强、成本低等特点，以全淹没和覆盖的方式扑灭A类和B类火灾，还可以有效地控制液化石油气和液化天然气的流淌火灾。

Post-mining or gob preventive injection, sand-filling or sealed separation in the gob with potential spontaneous fire, Visional judgement or index jndgement for prediction, nitrogene-injection for fire prevention, and control, spraying oxidation retardent to delay coal oxidati...

同时提出某些预防煤田自燃发火的对策——采后或采空区预防性注浆；对可能产生自燃火灾的采空区注砂或充填，加以封闭隔离；采用直观判断、指标判断等方法进行预测预报：注氮防灭火；喷涂阻化剂以延缓煤氧化；选择合理的开拓方式和回采方法：选择合理的通风系统和利于防火的通风方式；控制向采空区的漏风等。

Fire-fighting foam for these hazards can be supplied by fixed or semifixed piped systems. It can be applied through foam discharge outlets, which allow it to fall gently over the surface of burning fuel. And it can also be applied by portable hose streams using foam nozzles or subsurface injection systems.

消防泡沫可使用於固定式或半固定式系统，经由顶部放出口缓慢地排放至燃料表面，也可应用移动式喷嘴或底部注入式系统达到灭火目的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
