We have a pressure gauge on the side.

我们侧面装有一个压力。

Then, we covered how manometers and barometers measure pressure.

然后我们讲了压力作机 气压压力表。

Which is where manometers and barometers come in.

这就压力武之地。 气压大气压。

And so what happened is as I decreased that volume, what happened to the pressure gauge?

于，当我减小那个体积时，压力发生了什么变化？

A manometer is just a U-shaped tube with a fluid inside.

压力一个形状像 字母 U 充满液体。

Once the needle is inserted into the spinal canal, it's attached to a manometer, which is a device that measures the CSF pressure.

刺入腰椎管针与流体压力相连，来测量脑脊液压力。

The noise was even louder though than this may seem at first, because a pressure gauge located 161 kilometers away measured a sound of 180 decibels.

可这噪音比初看起来还要强，因为在距火山161公里处一个压力测量到声音180分贝。
