代表多出的一部分压强。
总压强的分压强。
由于两个分压都变大了，总体的压强也要变大。
And since both partial pressures are bigger, the total pressure has to be bigger.
但是这个分压是总压强的函数。
这分压等于气相中b的摩尔分数，乘以总压强。
It's the molar fraction of B in the gas phase times the total pressure.
现在看看分压如何，随着总压强变化。
Trying to see how the partial pressure of a changes with the total pressure.
台阶高度的不同对消力池底板脉动压强的影响十分微小。
But step height has less effect on on pressure of the stilling basin.
台阶高度的不同对消力池底板脉动压强的影响十分微小。
