However, the thing to remember is, when you look at heats of reaction under those conditions it's all well and good.

相反，需要记住，当你需要知道反应中放出的热量时,这些量是很有用的。

To ask questions like how much heat is released in a chemical reaction that takes place at constant temperature.

当我们想要知道,当一个化学反应在恒定的温度下发生时,会放出多少热量时。

What does come out, which is very useful is, if you do run the reaction, here's how much heat comes out.

能得到的结果是，如果我们进行这个化学反应，有多少热量放出，当然这也是很重要的。

You calculate how much heat is released in the reaction. And then what's going to matter is what's the heat capacity of the whole, of the calorimeter?

就是计算在反应中,放出了多少热量,接下来关键的是,整个量热计的热容是多少？
