主题：办公室内的设备 介词用OF OR IN ?

突出“设备在办公室”，用in。
如：The computer is in my office. 电脑在我办公室。
突出“设备是办公室用的”，用of
The computer of office. 办公室的电脑

应该是economies of scale吧，单词你咋写错呢

是该打！

你问的是英语的重中之重，即唯一的主根。可惜语法里，无一语及之。
1. in office = by way of  强调的是the way  of usage
2. of the office = of the office where it belongs ;
3. economise of scale 与之类同的有无数的多, here, the 'economise' is subjected to scale
native America = native of America
forest China = forest of China
the top of the hell  = the place of the top of (= belongs to / is) the hell
materials of low quality ； (here , the 'of ' is different from the 'of' in 'quality of service' ; to which the materials exist)
'quality of service' is the same as our talking on
a loss of identity

the other side :
the death of the king
he was died of cancer.
a man of strong shoulders XXX 错用
a man with strong shoulders
等等。。。。。。

办公室内的设备  介词用OF OR IN ?还是两个都可以？
这里用in较好。一般来说，in是特指，of 是泛指。 equipment/facilities of office = office facilities.

还有greater econimies of scale. 像这样的 句子，我会翻译成greater scale  econimies
这不能套 A of B =B 是 A 的公式。如译成“规模的较大经济”大蹩脚。应是“较大经济规模”， 但英文的表达也可是： greater scale of economy 或 economies of greater scale; greater scale in economy
