The higher the proton affinity, the stronger the base.

质子亲和力越高，碱越强。

Whereas the record-breaking ortho-diethynylbenzene dianion has a proton affinity of 440 kilocalories per mole.

而破纪录的邻二乙炔基苯双阴离子的质子亲和力为每摩尔 440 大卡。

But you can measure its strength based on its proton affinity: the amount of energy that’s released as it bonds with hydrogen.

但是你可以根据它的质子亲和力来衡量它的强度：当它与氢结合时释放的能量。
