A particular growing source of lead exposure comes from the recycling of lead acid batteries and these are a growing need in our society, whether it be for electric vehicles, whether it be for small scale uninterrupted power supply.

暴露的一个日长的来源来自于池的回收， 而这些池我们的社会中需求日，无论是用于动汽车，还是用于小型不间断源。

And so I like to think of it as like the UPS of your little factory.

所以，我倾向于把它比作你这小工厂里的UPS（不间断源）。
