The difference between the two puts physical stress on the windows - made up of three panes of glass.
两侧的气压差会对窗户造成物理压力。(飞机的窗子是由3层玻璃组成的)
There's a small air gap in between the middle and outer panes and the hole is actually in the middle pane.
在中层玻璃和外层玻璃之间有一个空气层,而这些小洞实际上是位于中层玻璃上的。
If you ever wondered what it's called - it's a "breather" or "bleed hole" - and it balances the pressure between the cabin and the air gap.
你可能好奇过它们叫什么。它们被称为“呼吸孔”或者“出血孔”——它们能平衡机舱与空气层之间的压力。
The outer pane takes the pressure, whereas the middle pane acts as a fail-safe just in case that trusty outer pane fails. Perish the thought.
承受压力的是外层玻璃,而中层玻璃则是一层保险,以防那层可靠的外层玻璃突然时效了。不过你还是打消这个想法吧。
So we now know the crucial function of those tiny holes in aeroplane windows which previously might have made you panic mildly.
好,现在我们已经知道飞机窗户上那些小洞有多么重要的作用了,而这玩意以前可能会给你带来点小恐慌。
And if you've ever wondered why aeroplane seats aren't always aligned with the windows, then there's an answer for that too.
