As if this thing bumps into all of the air particles as it is falling to the ground.

现在考虑更多的例子现在考虑更多的例子。

Those air particles are knocking one into another.

这些空气颗粒相互碰撞。

When you use the string phone, your voice makes the air particles in the cup start to vibrate.

当你使用绳电话时，你的声音会使杯子中的空气微粒开始振动。

But we also know that it looks like there's certain types of air, and certain types of air particles.

但我们也知道，看起来有某些类型的空气和某些类型的空气颗粒。

So these air particles are pushed outward at a very, very high velocity out the back of the engines.

因此，这些空气颗粒以非常非常高的速度从发动机后部向外推。

When any object moves through the air, it pushes on lots of tiny air particles, and those tiny air particles push back.

当任何物体在空气中移动时， 它会推动许多微小的空气粒子，而这些微小的空气粒子又会反推。

If you are to enlarge one of those air particles, let's say, this is this purple dot right over here.

如果你要放大其中一个空气粒子，比如说，这就是这里的紫色点。

Take a look at the video of how sound travels to better conceptualize this bouncing-like movement of the air particles.

观看声音传播方式的视频，以更好地概念化空气粒子的这种弹跳式运动。

Dozens of drones dispatched in a desperate attempt to battle toxic smog in Bangkok by spraying a water and molasses solution to catch air particles.

数十架无人机被派往曼谷，孤注一掷地试图通过喷洒水和糖浆溶液来捕捉空气颗粒物来对抗有毒烟雾。

This polka dot balloon is filled with high pressure air particles and when popped, all these particles rush out and hit the adjacent air particles.

这个圆点气球充满了高压空气颗粒， 当爆裂时，所有这些颗粒都会冲出并撞击相邻的空气颗粒。

So over here, you have this plane flying and the plane is able to move forward by pushing air particles through these jet engines.

所以在这里，你让这架飞机飞行，并且飞机能够通过这些喷气发动机推动空气颗粒向前移动。

When I slap this table top, or strum a guitar, those vibrations cause air particles to vibrate too, initiating sound waves that carry the vibration through the air.

当我拍打这个桌面，或者弹吉他时，这些振动也会导致空气粒子振动，引发声波，将振动传播到空气中。

Your body moves through the air, and hits the tiny air particles that are in the way, and those tiny air particles push back on you.

你的身体在空气中移动，撞到挡路的微小空气颗粒， 这些微小的空气颗粒又推回你身上。

And depending on what type of air particles you're looking at, whether it is carbon or oxygen or nitrogen, that seems to have different types of properties.

根据你所观察的空气粒子的类型，无论是碳、氧还是氮， 它们似乎具有不同类型的特性。

For a skydiver, the parachute takes up more space than her body would alone, so more air particles are pushing back to slow her, and the parachute, down!

对于一名跳伞运动员来说， 降落伞比她的身体单独占据更多空间，所以更多的空气粒子会向后推以减慢她的速度， 降落伞也会下降！

A device measures the force or pressure levels from the air particles in the concert hall or recording studio and graphs them into the grooves on a vinyl record.

一种设备可以测量音乐厅或录音室中空气粒子的力量或压力水平，并将它们绘制成黑胶唱片上的凹槽。

The low points in the waveform are called rarefactions, and they are where the air particles are more spread out and not bouncing around as much, and thus have a lower pressure.

波形中的低点称为稀疏点，此处的空气粒子更加分散， 不会反弹太多，因此压力较低。

Those particles hit the next set of adjacent particles, and so on , thereby creating an expanding shell of air particles just bouncing into one another This is called a pressure wave or sound wave.

这些粒子撞击下一组相邻粒子，依此类推，从而产生一个膨胀的空气粒子壳， 只是相互反弹。 这称为压力波或声波。

To play this record, a needle just needs to follow the recorded grooves, and convert this motion into the motion of a diaphragm, which applies a force to the air particles, thereby reproducing the original sound.

要播放这张唱片， 唱针只需顺着录制的凹槽移动，并将这种运动转化为振膜的运动，振膜会对空气粒子施加力，从而重现原始声音。

Even though popping the balloon makes a relatively simple sound when we take a cross section and zoom in on a molecular level we can see the complex pattern depicting how the air particles are bouncing into one another.

尽管气球爆裂的声音相对简单，但当我们取其横截面并放大到分子水平时，我们可以看到描绘空气粒子如何相互弹跳的复杂图案。
