“你眼鏡多少度”,“酒是多少度”,千萬別用 degree

“眼鏡”的度數(shù),“酒精”的度數(shù),

跟我們熟悉的degree其實(shí)根本不是一碼事!

01

酒精度的定義是指

酒中純乙醇(酒精)所含的容量百分比。

比如某酒100毫升中純乙醇含量為10毫升,

這種酒的酒度就是10度。

英語中可以表達(dá)為

Alcohol by volume

 

Alcohol by volume (abbreviated as ABV, abv, or alc/vol) is a standard measure of how much alcohol (ethanol) is contained in a given volume of an alcoholic beverage (expressed as a volume percent).

酒精體積(簡寫為ABV、abv或alcvol)是衡量酒精飲料中酒精(乙醇)含量的標(biāo)準(zhǔn)方法(以體積百分比表示)。

It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.4 fl. oz) of solution at 20 °C (68 °F).

它是指在20攝氏度(68華氏度)下,100毫升(3.4盎司)的溶液中所含的純乙醇的毫升數(shù)。

The ABV standard is used worldwide.

ABV標(biāo)準(zhǔn)在世界范圍內(nèi)使用。

例:

wine at 12% ABV

12度的酒

A:What's the alcohol content of QingDao beer?

青島啤酒的麥芽汁濃度是多少?(中文里“啤酒度數(shù)”一般指麥芽汁濃度,并不是酒精占比)B:It's about 7%.

大概百分之七。alcohol content

(酒精容量)
 

02

在眼鏡領(lǐng)域有這樣一個(gè)單位

Diopter

/da???pt?(r)/

a unit for measuring the power of a lens to refract light (= make it change direction)

屈光度

在英文中,眼鏡度數(shù)的單位是屈光度diopter

大家在視力檢驗(yàn)報(bào)告上就能看到屈光度,如果是-3.5D,這里的D就是diopter的縮寫。而-3.5D代表的也就是近視350度。

A “plus” (+) sign in front of the number means you are farsighted, and a “minus” (-) sign means you are nearsighted. These numbers represent diopters, the unit used to measure the correction, or focusing power, of the lens your eye requires. Diopter is often abbreviated "D."

數(shù)字前的加號(hào)就意味著你是遠(yuǎn)視,減號(hào)則意味著你是近視。這些數(shù)字代表屈光度,指能夠矯正你眼睛聚焦能力的鏡片的單位。

例:

I am nearsighted with 2.0 diopters.

我近視200度。

詢問別人眼鏡度數(shù):

① How strong are your glasses?

你的眼鏡多少度?/你近視多少度?

注意這里要用strong來修飾哈,度數(shù)越高,鏡片越厚(那不就是結(jié)實(shí)了么)

② How good is your vision?

你視力怎么樣?

如果你在對(duì)話中和朋友正在圍繞著眼鏡問題來聊

你也可以直接這么問:

What prescription are your glasses?

今天的內(nèi)容都學(xué)會(huì)了么?

歡迎評(píng)論交流心得~
