然后，计划建造一个带有氯乙管蹦床，但那只会成为鸟栖息地， 然后你就必须应对糟糕水质。

These are combined in a chemical reaction to create ethylene dichloride, which is turned into a gas, and then, through a process called " polymerization" , it becomes a fine, white powder called polyvinyl chloride, or PVC.

它们在化学反应中结合，成二氯乙，变成气体，然后，通过一个叫做“合”过程，变成一种白色细粉末，叫做氯乙，简称PVC。
