摘要双洞长大公路隧道一旦发生火灾，根据防灾与救援要求会开启两隧道间的部分横通道，此时整个隧道的通风网路风流状况对隧道防灾具有十分重要的作用。

To ensure human body's health, sanitation in driving vehicles crossing the tunnels as well as operation safety of tunnels, the present study take a highway tunnel(620m) as an example, combined with the data analyse of highway tunnel intelligent monitoring system to advance a discharge standard of NO2 concentration in highway tunnels and revelant ventilation solution.

为了保证城市公路隧道行驶机动车内人的健康、卫生和隧道的营运安全，本文以某隧道(620米)工程为例，结合隧道智能监控系统数据的分析，提出了在城市公路隧道内二氧化氮浓度的排放标准，并且提出了相应的通风方案。

A full-scale measurement of wind pressure distributionon a group of two 120m high,ribless hyperbolic natural draft coolingtowers in Beijing area is described in this paper.

在对两座高120米双曲线型自然通风冷却塔群的风压分布的全尺寸测量，特别是风压测量系统及其参考压力的测量方法介绍之后，分析了冷却塔运行方式及来流方向对塔面风压分布的影响；并将全尺寸测量与风洞实验及单塔实测结果进行了比较。

Cake tea, Jingua tea and Tou tea should be deposited on the wooden frame for good ventilation. It is better to choose wooden frame made from Saurauia oldhamii with loose texture and no peculiar smell.

散茶要用陶制的大瓮来装，饼茶、金瓜茶、沱茶要用木架陈放，以利于通风透气，木架最好选用材质疏松无异味的水冬瓜木制作。

The envelope contains a vent to permit ingress and egress of air from the pillow or cushion (3). The envelope also includes a sealable opening to permit insertion and removal of the pillow or cushion.

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission;the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB,but also adapt to the gas's characteristic involved with H2S,CO,and other poisonous components without supplied m...

通过选用耐油性好的橡胶隔振器减少固体传声，可降低噪声约2 dB；设置半封闭式机组隔声屏障可降低生产车间工作区域内的噪声达13 dB，并且适合瓦斯发电气源中含有H2S、CO等有毒有害气体的特点，不需增加强制通风措施；在生产车间四周墙壁和顶棚上敷设吸声体，最大可降低空间噪声8 dB；根据瓦斯发电机排烟噪声频谱特性设计的阻抗复合式消音器的消音量可以达到30 dB以上。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.
