据NASA解释，飞机在超音速飞行时会产生延伸到地面的加压空气分子锥。

Airplanes flying faster than sound create a cone of pressurized air molecules that extends to the ground, as NASA explains.

这些组件包括太阳能帆板的支撑桁架和一个被称为加压适配器(PMA)的连接装置，此装置能为航天飞机提供连接埠。

Those included a support truss for solar panels and a connecting unit called a Pressurized Mating Adapter (PMA). The PMA provided a docking port for shuttles.

在较高海拔区域气压较低，尽管飞机已经在加压了。

At higher altitudes air pressure is lower, even though the plane is pressurized.
