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另一聚合物尼龙时发生情况。

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，它可以依靠多呼吸摆脱最普通酸性形成分子，即二氧化碳，从而对酸碱值降低做出反应。
