朗文的解释(选个头两个词义)：
1 facilities [plural]：rooms, equipment, or services that are provided for a particular purpose: (为某种目的提供的)设施(如房屋、设备、服务等)。如：
toilet facilities 卫生间设施
childcare facilities 儿童保育设施
2 [countable usually singular] a special part of a piece of equipment or a system which makes it possible to do something: (一般用单数)设备，装置。如：
Is there a call-back facility on this phone? 这部电话有回呼装置吗？
a bank account with an overdraft facility 可以透支贷款的银行账户

因此，应理解为：“设备，设施”。
