Well, that difference in mass is equal to an amount of energy, specifically the total binding energy of the nucleus.

好吧，质量差等于能量，特别是原子核的总结合能。

But while the total binding energy still increases for nuclei larger than iron, the binding energy per nucleon, in fact, decreases.

但是，虽然对于比铁大的原子核，总结合能仍然增加，但实际上每个核子的结合能却降低了。
