Question

accelerator n.加速装置；油门；[物]加速器；[化]加速剂；促进剂 (1) 我们得换油门踏板。(2) 我猛踩油门,发动机发出了尖利的声音。(3) 很有可能，用这台加速器就能够找到部分子或夸克。 An accelerator gets things going. In a car, the accelerator is the gas pedal that you mash with your foot when you’re ready to speed off into the sunset. In physics, a particle accelerator speeds off in a different way — it takes a particle, such as an electron, and speeds it up to almost the speed of light, and smashes it into an atom. Why? To see what it’s made of.
