This is just what happens when hexamethylenediamine meets adipic acid forming another branded polymer, nylon.

这正是六亚甲基二胺遇到己二酸形成品牌聚合物尼龙时发生的情况。

For example, it can respond to decreasing pHs by getting rid of one of the most common acid forming molecules—carbon dioxide— by well, breathing a little more.

例如，它可以依靠多呼吸的方最普通的酸性形成分子，即二氧化碳，从而对酸碱值的降低做出反应。
