n.缺乏；不足；缺陷；缺點(diǎn)

I have a slight calcium deficiency. 我有點(diǎn)缺鈣。

The result in either case is an energy deficiency. 不論哪種情況結(jié)果都會(huì)導(dǎo)致能量損失。

Things will go much better if people of the same trade make up the other's deficiency from their own surplus. 同行業(yè)之間互通有無(wú)，調(diào)劑余缺，事情就好辦得多了。

It is diligence that makes up for deficiency. 勤能補(bǔ)拙。

It was the deficiency we were struggling to correct. 此一缺點(diǎn)我們正在努力改進(jìn)中。
