For many decades, even after being exposed to the elements, zincgalvanizing has protected your steel heating and cooling ducts.
镀锌表皮暴露在自然环境中，但它几十年来还是很好地保护了负责加热或冷却的钢制管道。

The adding of ni into the zinc bath or increasing of the galvanizing temperature can inhibit the reactivity partially. But the mechanism is not well understood.
通过往锌池中加入一定的镍或者提高镀锌温度，可以在一定程度上抑制硅的反应性，但机理不清楚。
