所以现在我们有一个， 等体，可逆的温度变化。

So now we have a constant volume reversible temperature change.

如果它发生了变化，当然在等体条件下，如果气体的总量，发生了变化，压强也会发生变化。

If that changes, of course you know that the pressure in there is going to change at constant volume if the amount of gas in there is changing.

自2008年全球经济崩溃以来，经济复苏初现苗头，但在卫生和教育等关键指标方面，主要经济体的经济状况仍持续下滑。

Yes, there has been a budding economic recovery since the 2008 global crash, but in key indicators in areas such as health and education, major economies have continued to decline.

How many moles of gas are there in each case, in reactants and products? If that changes, of course you know that the pressure in there is going to change at constant volume if the amount of gas in there is changing.

在反应物和生成物中，各有多少摩尔的气体？,如果它发生了变化,当然在等体条件下，如果气体的总量,发生了变化，压强也会发生变化。
