两个维护用英语怎么说

"Maintenance" 是维护的英文表达方式。这个词来源于拉丁语 "manutenere"，意思是 "to keep up" 或 "to preserve"。

一些英文例句和中文翻译如下：

The building needs regular maintenance to keep it in good condition.
(这栋建筑需要定期维护才能保持良好状态。)
The company is responsible for the maintenance of the equipment.
(公司负责设备的维护。)
He performs maintenance on his car every 3,000 miles.
(他每 3,000 英里就会对他的汽车进行维护。)

当描述两个维护时，可以用 "dual maintenance" 或 "double maintenance" 表示。
例如：

The aircraft has dual maintenance schedules for its engines and avionics.
(飞机的发动机和航空电子设备有双重维护时间表。)
