Energy content of fuel is obtained in most cases in an adiabatic, constant volume bomb calorimeter.

能源燃料的内容是，在大多数情况下取得的绝热，定容弹热量。

Could be done, but easier is to just do the whole thing at constant volume, right, and just run the reaction that way and redo the calculation to be a constant volume rather than constant pressure calorimeter, right.

可以进行测量,但是如果在体积恒定的条件下,做这些会容易得多,还是这样进行反应,但是在等体而不是恒压条件下重新计算。
