separated flame 火焰原子吸收光谱法为克服火焰的不稳定对测量精度的影响，使火焰的中间区与初级燃烧区分离，避免周围气流扩散到火焰中。 可用石英管套在燃烧器上方或利用氮气或氩气屏蔽火焰。 分离火焰可降低背景发射，改善<200nm光谱区的火焰透射性能。
实验中的电棒本质上是用电把火焰从燃烧器中推开，把它从燃料源中分离出来，然后火就熄灭了。
The electric wand in the experiments essentially uses electricity to push the flame away from the burner, detaching it from the fuel source, so it goes out.
气流也许强得足够将火焰与燃料来源分离开，可能就是火焰被熄灭的原因。
This flow may be strong enough to separate the flame from its fuel source, which may be why the flame goes out.
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。
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).
