大气压力

BACKGROUND: Venous air embolism is a potentially fatalcomplication of surgery when open veins at a surgical site areexposed to ambient air pressure which exceeds the pressure inthe venous system.

背景：外科手术中，术野开放的静脉暴露于周围的空气，大气压力超过了静脉系统压力，静脉气体栓塞可能成为手术致死的并发症。

Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere.

大气压力随高度的增加而降低，而大气的密度也如此。

Air may be provided adjacent each protrusion to provide natural ventilation if the pressure of the water flow drops below atmospheric pressure.

空气可提供邻近每个椎间盘突出提供自然通风，如果压力的水流量低于大气压力。

The vapour pressure at 320℃ is less than atmospheric pressure.

即使在摄氏320度时的汽化压力仍低于大气压力。

Up to about 14 psi of atmospheric pressure, the necessary pressure is achieved by vacating the space between the sheet and the mold in order to take advantage of this atmospheric pressure.

高达约14磅的气压，必要的压力是通过腾出空间之间的资产负债表摘要及模具，以充分利用这一大气压力。

Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere.

大气压力随高度增加而降低，而大气的密度也如此。

Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere.

大气压力随高度增加而降低，大气密度也随着高度增加而降低。

Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere.

大气压力随着高度增加而降低，大气密度也随着高度增加而降低。

Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere.

大气压力随高度增加而降低，大气密度也随高度增加而降低。

根据大气压力随距海平面高度而逐渐衰减的函数关系，通过测量大气静压间接测量飞行高度的仪表。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
