Frozen type air dryer by lowering the temperature of compressed air to close to the freezing point of water, that extra water vapor condense into liquid water, thus and flow separation.

冷冻式空气干燥器通过降低压缩空气的温度至接近水的凝固点，使多余的水蒸气凝结成液体水，从而与气流分离。

Within about a millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor.

在离水不到一毫米的地方，空气的温度接近于地表水的温度，空气中的水蒸气几乎饱和了。

Since a plant uses it up in the air around, the plant needs moving air to bring more CO2 close to its surface!

由于植物会将周围空气中的二氧化碳耗尽，因此需要空气流动将更多的二氧化碳带到其表面！

"There were some problems with some tactics, techniques and procedures, the way in which close air support was supposed to have been executed in this case, such that, at least with one of the aircraft involved, a B-1 bomber, that plane because of how it takes its bombing routes had to break away from positive I.D.

We're still close enough to the summer that the air is not just filling us up with extra static electricity, so it's a little more challenging here.

我们现在离夏天更近了,这样空气中不总是,充满额外的静电，所以这时做实验,会有一些挑战性。

They affect the air and the ability to provide close air support, and they provide cover for forces that want to get along your supply lines and shoot at you close.

If Angola commits its relatively well-equipped air force to Congo, it could close the air-bridge the rebels are using to ferry troops from the east to their western front.

So if the C919 is to be commercially viable, COMAC needs to get the plane up in the air on or close to its ambitious schedule while the market for medium-range aircraft remains hot.
