So, two Italian businessmen built a piston engine hydroplane named Laura 3.

于是，两位意大利商人制造了一架活塞式发动机水上飞机，劳拉三号。

Like these air pistons he uses to launch food.

比如他用来发射食物的这些气压活塞。

Like these air pistons he uses to launch food or these catapults.

就像这个他用来发射食物的气阀活塞，或是这些弹射器。

The pistons in the engine. Of the car. Just don't drive.

活塞在汽车引擎中，也就是说不要开车了。

There's a piston inside the truck and it's pushing back the whole time.

卡车里有一个活塞，它一直在向后推。

But we're still against driving while intoxicated-so if you're gonna be toking, keep those pistons from stroking.

但是我们仍然对吸食大麻后驾驶——如果你要吸食大麻，那就别让汽车活塞活动。

It's a project made up of scrap metal air pressure pistons and the imagination of an artist named.

艺术家Koliakugla凭借自己的想象力，利用废旧金属气压活塞组成这个乐队。

As the piston lowers, air and fuel are sprayed into the cylinder's chamber.

活塞下降时，空气和燃料会被喷入汽缸腔内。

The roar of mighty piston engines overhead tranfixed midday strollers and crowds along the National Mall.

强力活塞式发动机的轰鸣声让国家广场中午散步者和人群感到聋。

It's cool to see how they all banded together firing on all pistons to make their music play out.

看他们配合起来打开所有活塞，演奏音乐，真的是一件很酷的事情。

They use hydraulic pressure to work their legs like pistons, catapulting up to 30 times their own body length.

它们利用水压的原理，像活塞般地移动它们的腿，可以弹跳远达身体30倍的距离。

What powers these pistons' movements is what gives these engines their namesake: combustion.

活塞运动提供动力的正是这些发动机的字：燃烧。

As the noise of the pistons fell away, the wind and rain sounded louder than ever against the windows.

车轮的声音小了，窗外的风雨声更大了。

She'll do it; she'll do it; she'll do it, said Potts to the beating rhythm of the piston rod.

她一定能做到，一定能做到，一定能做到，波茨对有节奏感的活塞杆说。

Hopefully you understand that the piston goes up and down now.

你应该已经了解了活塞是如何上下运动的。

This combustion causes an immediate increase in temperature and pressure, propelling the piston down, as it starts the cycle again.

这种燃烧会让温度和压力立即上升，把活塞推下来，开始下一次循环。

Steam rushed whistling into the gaping valves. Long horizontal pistons groaned and pushed the tie rods of the drive shaft.

蒸汽涌入半开的机关中；发出呼呼的啸声。一排排横列的活塞发出格格的声响，推动机轴的杠杆。

That piston going up and down, changes the up and down force into a rotating force.

因活塞上下运动会将上下力变旋转力。

Now that the piston is moved down, the cycle resets and these two valves open.

现在活塞向下移动，循环重新开始，这两个阀门打开。

And obviously, Pistons are having a tremendous season and are coming out of it.

显然，活塞队正经历一个极出色的赛季，并逐步走出低谷。
