[译]钢铁工业安装了其他大规模的节能设备。
[误]The steel industry installed other large-scale energy saving equipments.

[正]The steel industry installed other large-scale energy saving equipment.

[注]名词 equipment 一般不用复数。又如：What kind of equipment are you talking about? I mean production equipment for ICs, colour TVs, and VTRs. 你讲的是哪类设备？我指的是集成电路、彩色电视机和磁带录像机的生产设备。
