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

玻璃管冷却后，他们会将电极固定在两端，然后用真空泵抽出气体。

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

而且，幸运的是，大约在这个时候， 发明了真空泵。

Twice a week, early in the morning, ACEA operators pull out their vacuum pumps to clear debris.

每周两次，清晨时分，ACEA的运营人员会取出他们的真空泵，清理杂物。

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

火焰随时会到真空泵， 并将整个底盘延伸到油箱。

Now you can see there's a vacuum pump over here so we can get rid of our atmosphere and then we just add energy to it.

现在你可以看到这里有个真空泵，这样我们就能去除大气层，然后我们只需向其中加入能量。

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.

如果你使用真空泵对氦气进行抽真空，其沸点会进低， 可以达到接近绝对零度两度的水平。

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.

将温度升至200摄氏度可去除所有水分，而数百台真空泵则需花费两周时间， 才能从管道中抽取足够的气体和碎片， 以满足对撞机极其敏感的实验需求。

One important detail is that when the microscope is running and electrons are being accelerated to relativistic speeds, vacuum pumps are used to remove all the atmospheric molecules, thus creating a vacuum similar to the vacuum of outer space.

个重要细节是， 当显微镜运行且电子被加速到相对论速度时，会使用真空泵移除所有大气分子，从而创造出类似外太空的真空环境。
