1·To deal with this problem, it is necessary to research and improve the air exhaust system.

为了解决这些问题，需要对铝电解机械排烟工艺进行研究改良。

2·HPLC, GC-MS, AAS, and spectrometer atomic fluorescence on 5th floor need air exhaust function.

液相色谱、气相色谱、原子吸收、原子荧光室前处理间或缓冲间需要进行排风。

3·Unique air exhaust device which completes exhausting the steam and vapor from the heating oven.

特殊排气装置，可将烘箱内水气及废气排除。

4·Purpose: Discussing the relation between closure pneumothoraxs air exhaust time and curative effect.

目的：探讨闭合性气胸抽气时间与疗效的关系。

5·The reason why the automatic exhaust valve failed to be used for air exhaust from siphon tube was investigated.

对自动排气阀不能用于虹吸管排气的理由进行了分析。

6·The thrust reverser (T/R) system controls the direction of the fan air exhaust to make forward or reverse thrust.

反推装置（T／R）系统控制风扇叶片气流 的排气方向从而实现正推力和反推力。

7·The carrying capabilities under three active throttle modes of air inlet, air exhaust and air inlet-exhaust are given.

给出了进气、排气、进气-排气三种主动节流方式下的承载能力特性。

8·One machine with multi-pipe operation, Where three sets of air exhaust or are fixed and used independently or parallelly.

一机多管作业，本机装有三套抽气头，可单独或并联使用。

9·The utility model relates to an exhaust duct that prevents head wind, especially to a movable air discharging door type one-way air exhaust device.

本实用新型涉及一种防逆风排风管，特别是涉及一种活动排风门式的单向 排风装置。

10·For the air exhaust plus smoke evacuation system, the problem of secondary smoke evacuation arises when smoke spreads to adjacent smoke-control zones.

摘要对于排风兼排烟系统，当烟气蔓延至相邻防烟分区时，将产生系统二次排烟问题。
