压力变化速率对火焰传播和燃烧室充气过程也有重要影响，应当加以考虑。

Moreover the rate of pressure change also plays an important role in the phases of flame-spreading and chamber-filling, and should hence be accounted for in the prediction.

Well, I can, for any given case, measure the pressure, determine the entropy and I'll know what the slope of change will be.

好的，对特定的情况，我可以测量压强，确定熵,并且知道这就是变化的速率。
