测试本身只是一种工具，可以在特定条件下以合理的精度测量其特性。

The tests themselves are merely tools, with characteristics that can be measured with reasonable precision under specified conditions.

Now, you know with constant volume, H now it's not going to be delta H that's U straightforward to measure, it's going to be dealt u, all right.

好，现在你们知道在体积恒定的条件下，我们得到的不是Δ,我们直接测量到的是Δ,好，但这基本上也是一样的。

And again there, too, you saw an experimental result you were presented with that says, well at least to the extent that it could be measured, it was obviously getting very small.

再一次，你看到了一个,你经知道的实结果，至少在实验测量的范围内，对理想气体条件下的气体这一项很小。

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。
