1·If time is long enough, the hazardous areas will not exist as gas concentration is diluted by air.

随着时间的延长，泄漏气体不断被空气稀释而使得浓度降低，若时间足够长，危害区域将不再存在。

2·Acrylic resin is diluted in ethyl acetate and the remnant monomer is well separated from it by gas chromatography and is quantificationally measured by hydrogen flame ionization detector (FID).

乙酸丁酯稀释丙烯酸树脂后，用气相色谱法使丙烯酸树脂中的各种残余单体得到较好分离，再采用氢火焰离子化检测器(FID)定量测定。

3·An exhaust pipe is connected to the dilution box (32), and diluted hydrogen gas is discharged via the exhaust pipe (38).

排气管(38)被连接在稀释箱(32)上，稀释的氢气经过排气管(38)排出。
