零件部门的英文是"parts department"。

这个词的来源可以追溯到拉丁语,"parts" 源自拉丁语的 "pars",意思是 "一部分"。"Department" 源自法语的 "département",意思是 "分开"、"分离" 或 "分支"。所以,"parts department" 意思就是零件分离的部门。

下面是一些例句:

Can you tell me where the parts department is located? (你能告诉我零件部门在哪里吗?)
I need to order some parts from the parts department. (我需要从零件部门订购一些零件。)
The parts department is responsible for ordering and stocking all of the parts for the company. (零件部门负责为公司订购和储存所有的零件。)
