May 30, 2013 · I purposely didn't mention I/O & c/o in my previous comment as I was aware of those. In particular, c/o has been used as long as I can remember. But otherwise this suggests I was roughly correct. Of course, it doesn't indicate what the abbreviations meant (e.g. A/C - see prev. comment.) I suppose also that w/o would show up as both w/o & w/? –

个人觉得这种缩写相对比较少见，常见有用点或者首字母缩写取代的趋势。 这种斜杠缩写，比较常见的就是 w/ = with, w/o = without 之类的，可能还有小伙伴在购房时看到过 w/d = washer and dryer，洗衣间。

现目前已经有ai 9 365的轻薄本了，但都是同型号的8845h版本换装cpu版本，同型号不同cpu，机器性能释放激进程度也没有变，8845h版本给多少w，ai 9 365也给多少w，就是基准强度的差距！

Sep 29, 2012 · χw (under which Indo-Eur. q w and kw were levelled), which appears as hw in the early forms of the Germanic languages, but is variously modified in their modern forms, appearing in High and Low German as w, in the Scandinavian languages, according to dialect, as hv, kv, and v, in English as wh.
