After the glass cooled, they attached electrodes to each end and removed the air with a vacuum pump.

玻璃管冷却后，他们极固定在端，然后用真空泵抽出气体。

And, luckily, at about this time, a vacuum pump had been invented.

而且，幸运是，大约在这个时候， 发明了真空泵。

At any moment the flames would find the vacuum pump and run the whole length of the chassis to the tank.

火随时找到真空泵， 并整个底盘延伸到油箱。

If you use a vacuum pump to pump hard on the Helium, the boiling point will go even lower, and you can go to nearly two degrees absolute.

如果你用真空泵用力抽氦气，沸点更低， 可以达到近绝对值。

Raising the temperature to 200 degrees Celsius burns off any moisture, and hundreds of vacuum pumps take two weeks to trap enough gas and debris out of the pipes for the collider's incredibly sensitive experiments.

温升高到 200 摄氏燃烧掉所有水分，数百个真空泵需要周时间才能从管道中捕获足够气体和碎屑，用于对撞机极其敏感实验。
