As altitude increases, atmospheric pressure decreases.

随着海拔的升高，大气压降低。

The pressure decreases as the blood flows from arteries into capillaries and finally into veins.

通常只测定动脉血压。

According to Boyle's Law, lung pressure decreases as a result of the increased volume.

根据波义耳定律，肺内压随着肺容积的增加而降低。

That makes the gas’s volume expand and its pressure decrease – path a-b on this diagram.

这使得气体体积膨胀， 压力降低——图中的路径 a-b。

The temperature drops while the heat stays constant, which also makes the volume expand and the pressure decrease.

温度下降，而温度保持不变 常数，导致体积膨胀和压力减小。

Atmospheric pressure decreases as less air surrounds us at higher elevations and pressure is needed to push oxygen into the blood.

在海拔较高的地方，随着周围空气减少，大气压力降低，需要压力将氧气推入血液。

Their blood pressure decreased, their cholesterol levels went down, their blood sugar and insulin levels dropped dramatically, and their liver function got better.

他们的血压下降， 胆固醇水平下降， 血糖和胰岛素水平急剧下降，肝功能得到改善。

As the magma rises, the pressure decreases, causing the gases to expand and propel the magma upwards through the volcanic conduit, resulting in an eruption.

随着岩浆上升，压力下降，导致气体膨胀并推动岩浆向上穿过火山管道，导致喷发。

In other words, there is an inverse relationship between the volume and the pressure of a gas: the pressure decreases when the container's volume increases.

换言之，气体的体积与压力成反比：当容器体积增大时，压力减小。
