Air rushes into the pleural cavity, and the intrapleural pressure increases as it equilibrates with the atmospheric pressure.

气体涌入胸膜腔，随着逐渐与大气压保持平衡，胸膜内压升高。

The lower intrapleural pressure outside the lungs creates a vacuum that keeps the lungs expanded and prevents them from collapsing.

肺外较低的胸膜腔内压产生真空环境，使肺保持扩张，防止肺塌陷。

Transpulmonary pressure is the difference between the intrapleural pressure (outside of the lungs) and the intrapulmonary pressure (that's inside the lungs).

肺间压（Transpulmonary pressure）指胸膜内压（肺外）和肺内压（肺内）之间的差值。

The intrapleural pressure is the pressure within the pleural cavity and it is always less than intrapulmonary pressure, which is the pressure inside the lung.

胸膜腔内压指胸膜腔内的压力，肺内压指肺内的压力，胸膜腔内压始终小于肺内压。

The pressure within this pleural cavity is referred to as the intrapleural pressure, and it is less than the intrapulmonary pressure - that's the pressure within the lungs.

这个胸膜腔内的压力被称为胸膜内压力，它小于肺内压力——肺内压力。
