AC/DC 条 @LDOCE
本帖最后由 Oeasy 于 2016-11-19 23:12 编辑读到 AC/DC ，发现朗五双解只有一个义项：
adj informal
sexually attracted to both men and women 【非正式】 双性恋的
https://www.pdawiki.com/forum/data/attachment/album/201611/19/230931afhfrmhn6zufrtaz.png
这和我的认知有差距，这 AC/DC 不就是交流电/直流电吗？怎么连这个意思都没有。又查了下，发现 LDOCE4 和 LDOCE6 这条内容分别如下：
LDOCE4 双解
1 informal sexually attracted to both men and women 【非正式】 双性恋的
2 used to refer to electrical equipment that can work on either ALTERNATING CURRENT or DIRECT CURRENT 交流电直流电两用的
https://www.pdawiki.com/forum/data/attachment/album/201611/19/231027jzmqr0m0r66rz3c0.png
LDOCE6 http://www.ldoceonline.com/dictionary/ac-dc
1 sexually attracted to both men and women
2 alternating current or direct current
{:4_109:}
o大，你真仔细，怎么发现的？醉了也是！ 看来朗文4双解也不能丢，还得和郎5双解一起用{:4_97:} 西方这几年政治正确真厉害啊，与HOMO有关的词条少了就不行大概 MED online 里 AC/DC 释义也不含 交流电/直流电，要单独查询 AC、DC 才行。
LDOCE5 Viewer.exe 里 AC/DC 释义与朗五双解相同，Word Origin 是讲电流：
AC/DC
Date: 1900-2000
Origin: alternating current/direct current two different types of electric current 朗文和柯林斯手机app的解释 本帖最后由 spearonsquare 于 2016-11-20 10:53 编辑
Encarta的解释还是不错的：
1.powered by battery or electrical outlet: able to be powered by battery or by connection to an electrical outlet. Full form alternating current/direct current
2.offensive term: an offensive term meaning bisexual (slang)
http://www.etymonline.com/index.php?term=ac%2Fdc
AC/DC (adj.) Look up AC/DC at Dictionary.com
electronics abbreviation of alternating current/direct current, by 1898. As slang for "bisexual," 1959, said to have been in use orally from c. 1940; the notion is of working both ways.
但是：
http://www.collinsdictionary.com/dictionary/english/ac-dc
C20: humorous reference to electrical apparatus that is adaptable for alternating current and direct current
Collins的这个解释是否有点儿问题？
ODE也不错：
https://en.oxforddictionaries.com/definition/AC/DC
1Alternating current/direct current.
2informal Bisexual.
从多个词典义项和下图可以看出，AC/DC连用表示直流/交流共用的含义现在不太使用了。
高手在民间呀！
