A barometer is useful in predicting the weather.

压计在预测面很有用。

This is often seen as a trough or cold front, also known as a cool change, shifting the direction of the wind, altering the course of the fire and broadening the fire front.

这个是常见的低压或者叫峰，也是众人所知的降温，降温改变了风向，改变了大火行进路线，并且拓宽了火线。

There are many signs that can help you. For example, in fair weather the air pressure is generally high, the air is still and often full of dust, and far away objects may look vague.

许多记号都能帮到你。例如，晴的压通常很高，空平静又经常带有尘土，远处的物体看起来有些模糊。

Air rushes into the pleural cavity, and the intrapleural pressure increases as it equilibrates with the atmospheric pressure.

体涌入胸膜腔，随着逐渐与大压保持平衡，胸膜内压高。

Blame the bomb cyclone. Yep, that's right. Bomb cyclone is actually a real weather term.

这都是炸弹低压所致。是的, 这是正确的。这实际是一种真正的象术语。

From using complex laws of physics to test whether a spinning egg is cooked to measuring atmospheric pressure by lifting a piece of cardboard.

从使用复杂的物理定律来测试旋转的鸡蛋是否被煮熟，到通过浮起一块纸板来测量大压力。

Polynomials describe the relationship between several variables - like range and air pressure, or amount of pizza Carrie Anne eats and happiness.

多项式描述了几个变量之间的关系 例如射程和大压力，或者Carrie Anne要吃多少披萨才会开心。

The weather is constantly in flux. A low pressure system allows moist air to rise, cool and form rain clouds.

是变幻无常的。低压系统使潮湿的空，凝，形成降雨云。

We are dealing with a pressure differential of around 1,100 atmospheres.

而我们要经历大约1100个大压的压差。

There, the pressure is so low that people can't survive without a special protective suit...

那里的压很低，人们没有特殊的防护服就无法生存下去。

Like these air pistons he uses to launch food.

比如他用来发射食物的这些压活塞。

So, I think 100 metres is the equivalent of 1 atmosphere.

所以，我认为100米深等于1个大压。

When a spacecraft goes up into space, they're only experiencing a pressure change of one atmosphere between the inside of the spacecraft and the outside.

当航器进入太空时，只会经历航器内部和外部之间的大压力变化。

It occurs when a storm's air pressure drops 24 millibars in 24 hours and generally speaking the lower the pressure, the stronger the storm.

这种现象在风暴的压于24小时内下降24百帕时发生，通常来说压越低，风暴就越强。

We are dealing with a pressure differential of around 1,000 atmospheres.

我们处理的是大约1000个大压的压差。

The air pressure at sea level is nearly 15 pounds for each square inch.

海平面的大压力每平英寸大约有15磅。

It hit Bermuda as a Category 1 hurricane and strengthened to Category 2 status on September 14th but then it lost strength and speed over the Atlantic and wondered as a low-pressure system until Monday.

Paulette作为一类飓风袭击了百慕大地区，并在9月14日加强成为了二类飓风，但是它随后在大西洋空削减了力量和速度，直到周一它还是一个低压系统。

In 1643, another Italian called Evangelista Torichele, invented the first barometer, which measured atmospheric pressure.

1643 ，另一位名叫伊万杰里斯塔·托里切勒的意大利人发明了第一个压计，用来测量大压力。

OK. Well, if you can, it's really amazing, because my voice is changing the air pressure where you sit by just a few billionths of the atmospheric leve.

好的。如果你能听见，那真是不可思议，因为我的声音会改变你身边的压，改变程度只有大压的几十亿分之一而已。

And now we're diving into the sun, where pressures rise over 100 billion atmospheres.

现在我们潜入太阳，那里的压强超过一千亿个大压。
