Just make sure it's not pulling in outside air.

只要确保它不把室外空气吸进来即可。

Exposed to the outside air, the thermometer marked -2 degrees to-3 degrees centigrade.

温度表放在外面，指着零下二度至三度。

Water running through the channels absorbs heat and transfers it to the outside air.

从管道流过的水吸收热量将其排出室外。

The less surface area they have exposed to the outside air, the less water can escape out.

它们暴露在外界空气中的表面积越小，水分就越少。

They let outside air into the humid cavity through tiny holes which are controlled by hermetically sealed valves.

它们通过受密闭阀门控制的小孔让外界空气进入潮湿的体腔。

The scent of pie and fresh coffee filled the air outside.

外面的空气中弥漫着馅饼和新鲜咖啡的香味。

In this case, the expression, fresh air, means being able to breathe the air outside.

在这种情况下，表达，新鲜空气，意味着能够呼吸外面的空气。

And as the chemical condenses, it releases heat energy – that heat is then transferred to the outside air that's blowing over the coils.

当化学物质凝结时，它会释放出热能——这些热量随后被传递到外面的空气中，空气在盘管上流动。

We Yawn More When It's Cool Gallup's theory predicts that colder outside air should cool the brain better than hot air.

盖洛普的理论预测，寒冷的室外空气比热空气更能使大脑降温。

As the machine smoked, outside air came through those ventilation holes and diluted the amount of smoke that was coming through the cigarette.

当机器抽烟时，外部空气通过这些通风孔进入， 稀释了从香烟中冒出的烟雾量。

For example, what a fool a builder must be to open a ventilator into another room, when, with the same trouble, he might have communicated with the outside air!

例如，造房子的人有多么愚蠢，竟会把通气孔朝向隔壁房间，花费同样的工夫，他本来可以把它通向户外的。

The pressure inside your car is going to be equal to the outside air pressure, which we’ll take to be the standard atmospheric pressure, or 101,325 Pascals.

你车内的压力将等于外部气压， 我们将其视为标准大气压， 或 101, 325 帕斯卡。

The pressure inside your car is going to be equal to the outside air pressure, which we'll take to be the standard atmospheric pressure, or 101,325 Pascals.

车内压力等于车外空气压力 我们认为它是 101，325 Pa 的标准大气压。

Then the diaphragm relaxes again, and the weight of the ribs settles in, and the pressure inside the lungs becomes higher than the outside air, and the air rushes out.

然后横膈膜再次放松，肋骨的重量沉淀下来，肺部内的压力变得高于外部空气，空气冲出。

Basically, you can make a pocket of lower air pressure in your mouth, so the water you’re trying to drink gets pushed up by the higher-pressure outside air.

基本上，你可以在嘴里制造一个气压较低的口袋，这样你想喝的水就会被外部气压较高的空气推高。

This big differences in pressure make it easy for oxygen molecules to travel from the outside air into your blood plasma, because, as a rule dissolved gases always diffuse down their partial pressure gradients.

这种巨大的压力差异使得氧分子很容易从外部空气进入血浆，因为，作为一项规则，溶解气体总是沿着它们的分压梯度扩散。

Um, so the estimate is that our car is roughly 10 degrees warmer than the outside air temperature, which puts the inside of the car about 50 degrees C Um, obviously it's very warm.

嗯, 所以估计我们的车里大约比外面的气温高10度左右, 这样车里面就大概有50度左右嗯, 显然是很暖和的。

This makes the pressure inside the lungs lower than the air outside your body, and — since fluids like gases move from areas of high pressure to low pressure — the lungs fill up with outside air.

这使得肺部的压力低于身体外部的空气，并且——由于液体，比如气体，从高压区移动到低压区——肺部充满了外部空气。
