And if you work out the energetics as we've gone with thermochemistry, dH you discover there's a huge negativedelta h.
如果你计算能量变化，就像在化学热力学中所作的一样，你会发现很大的负的。

And so, in fact, the delta here is negative.
因此，实际上这里的delta, e是负的。

If the delta is ever negative, consider that an error, as you should never get an item from the queue with an earlier trigger time, when the delay has ended.
