Total pressure on the cabin was 200,000 tons, like 100 WW2 Navy destroyers piled on top of you.

下潜舱承受的总压力是 20 万吨，相当于 100 艘二战时期的驱逐舰压在你身上。

So what's the total pressure inside the tank?

那么罐内的总压力是多少？

What is the partial pressure of O2 in air at a total atmospheric pressure of 97.8 kPa?

在总大气压为 97. 8 kPa 的情况下， 空气中 O2 的分压是多少？

A central tenet here is Dalton's law, which states that the total pressure of a mixture of gases is due to the combined influence of the individual gases comprising the mixture.

这里的一个中心原则是道尔顿定律，它指出气体混合物的总压力是由构成该混合物的各个气体的综合影响引起的。
