Question

emit 【emit】v.放射Heat and smoke emitted by the fire made it difficult for the firemen to put it out.火所放射出的热和烟，使得消防队员很难将火熄灭。

Accepted Answer

[i'mɪt] 
emitgive off, send forth, or discharge; as of light, heat, or radiation, vapor, etc.
To emit means to give off or let out, and it usually has a lot to do with gases, smells and noises. All of which could be potentially embarrassing, depending on where they're coming from.
Lots of things can be emitted: body heat from your hands, high pitched sound waves from a dog whistle, nasty odors from your mouth after a garlic-heavy lunch. Coming from the Latin emitter, it simply means to “send forth.” Since global warming is such a hot topic, you've probably heard people talking about how much CO2 cars emit or how many greenhouse gases factories emit into the air.
