1) air embolus detector
空气栓塞探测器
5) air pressure probe
空气压力探测器
6) air sampling smoke detector
空气采样探测器
1.
Relying on the fire simulation platform of FDS, the parameter calibration methods for spot-type and air sampling smoke detectors were proposed with considering of their respective working characteristics: time-lag effect and diluting effect.
结果表明:点型探测器对小功率火探测失效;空气采样探测器探测效果受管网布置影响较大,水平管结合下垂管的组合采样方式能有效克服热障环境影响,对各种火灾情况应对能力强,尤其对小功率火探测优势明显。
2.
To study the working performance of contact smoke detectors in large space fire,numerical wind tunnel experiments and ASPIRE2 program were adopted respectively to model the process of smoke entering the sensing chamber of two kinds of detector products:spot-type smoke detector and air sampling smoke detector.
结果表明:点型探测器对小功率火探测失效;空气采样探测器探测效果受管网布置影响较大,水平管结合下垂管的组合采样方式能有效克服热分层环境影响,对各种火灾情况应对能力强,尤其对小功率火探测优势明显。
补充资料：肺空气栓塞
肺空气栓塞
air embolism of lung,pulmonary air embolism
外伤或医源性损伤大静脉，空气进入血流通过右心达肺动脉，造成肺动脉小分支和毛细血管广泛栓塞。若进入血流的空气量很少，可逐渐被吸收。大量空气进入血流则严重影响静脉回心血量和肺循环，出现严重缺氧、呼吸困难、发绀甚至死亡。微小气栓可通过肺毛细血管进入体循环引起冠状血管及脑血管等栓塞而造成严重后果。
