1) zonal ventilation
区域通风
2) ventilated area
通风区域
3) regional auxiliary ventilation
区域辅助通风
1.
The variation rule of methane,dust and other components in the regenerated airflow of the regional auxiliary ventilation system is theoretically analyzed.
针对白集煤矿深部开采出现的通风困难、风量不足和热害环境等问题,提出有利于热环境改善的区域辅助通风技术方案,设计了一套由喷雾降尘装置、过滤装置和冷却降温装置组成的再生风流处理系统,在理论上分析了区域辅助通风系统再生风流中瓦斯、粉尘和其它气体成分的变化规律。
4) zone/system ventilation efficiency
区域/系统通风效率
6) risky area
风险区域
1.
The result shows that the risky area is closely related with not only the source term,but also the meteorological conditions and the time after the accident;the high concentration zone spread near the leaking point under the unstable and strong winding meteorological conditions,while,the high concentration zone not only lasts for a long time,but also has the transportation function under the.
结果表明,风险区域不仅与氨气泄漏的源强有关,而且与事故状态下的气象条件密切相关,在风速大、不稳定的气象条件下,有害气体泄漏在空气中形成的高质量浓度区多分布在事故源的近距离处;而在静风、稳定的气象条件下,高质量浓度区不仅持续的时间长,而且伴随着空气的稀释作用,随风力的输送向下风向飘移。
2.
It is very complex engineering system for the emergent assistance at the leaking accident of the toxic and harmful gas,and the key to the settlement of the question lies the right determination of the potential risky area.
突发性事件的救援工作是一个非常复杂的系统工程,而关键问题是及时准确地确定风险区域。
