Under the condition that the sealing door is closed, the internal and external pressure is not balanced, which will threaten the safety of the building envelope.

在密封门关闭的情况下，容易产生内外压力不平衡，将会威胁到库体围护结构的安全性。

And use the fourth strength theory, the axial tension in the coiled tubing under the influence of internal and external pressure from a comprehensive stress of checking.

并利用第四强度理论，对连续油管在轴向拉力与内外压力的作用下的综合应力进行了校核。

Why is there both external and internal pressure to look "perfect"?

为何会有外在和内在的双重压力来让自己看起来“完美”？

Because it's so important. And I should add and also under reversible work, where the external pressure is equal to the internal pressure.

而且我还要说应该在外部压强,和内部压强相等的,可逆过程中引入它。

So it's going to shoot up until the internal pressure and the external pressure are in equilibrium.

活塞将上,移直到内外,压强达到平衡。

It's reversible, that means that p external, equals p. I'm doing it very slowly so that I'm always in equilibrium between the external pressure and the internal pressure so I can go back and forth.

我都可以不损失能量，而把过程逆向进行,整个过程中的,每一步都保持平衡,现在我们来分别。
