符号 @ 来源之谜（双语）

That little "a" with a circle curling around itthat is found in email addresses is most commonly referred to asthe "at" symbol。

小写字母“a”外加个圆圈，这一符号常出现在email(电子邮件)地址中，通常是作为“at”(在)的标记。

Surprisingly though, there is no official,universal name for this sign. There are dozens of strange terms todescribe the @ symbol。

然而令人感到惊奇的是，这一标记居然没有官方的，通用的名称。有几十个奇怪的术语用来描绘@这一符号。

Before it became the standard symbol forelectronic mail, the @ symbol was used to represent the cost orweight of something. For instance, if you purchased 6 apples, youmight write it as 6 apples @ $1.10 each。

@这一符号在成为电子邮件的标准符号之前，曾被用来表示物品的单价或质量。例如，你买6只苹果。就可以写成：六只苹果，每只@$1.10，表示每只苹果1.10美元。

With the introduction of e-mail came thepopularity of the @ symbol. The @ symbol or the "at sign" separatesa person's online user name from his mail server address. Forinstance,joe@uselessknowledge.com. Its widespread use on theInternet made it necessary to put this symbol on keyboards in othercountries that have never seen or used the symbol before. As aresult, there is really no official name for thissymbol。

随着电子邮件的使用，@这一符号越来越普及了。符号@或“at”标记将上网用户的姓名与其邮件的服务器地址分开。例如：joe@uselessknowledge.com。这一符号在因特网上的广泛使用使得许多以前从未见过或使用过它的国家必须在它们的电脑键盘上加上这一符号键，结果造成这一符号并没有真正的官方名称。

The actual origin of the @ symbol remains anenigma。

@符号的确切起源仍然是谜。

History tells us that the @ symbol stemmed fromthe tired hands of the medieval monks. During the Middle Agesbefore the invention of printing presses, every letter of a wordhad to be painstakingly transcribed by hand for each copy of apublished book. The monks that performed these long, tediouscopying duties looked for ways to reduce the number of individualstrokes per word for common words. Although the word "at" is quiteshort to begin with, it was a common enough word in texts anddocuments that medieval monks thought it would be quicker andeasier to shorten the word "at" even more. As a result, the monkslooped the "t" around the "a" and created it into acircle-eliminating two strokes of the pen。

历史告诉我们，@这一符号起源于中世纪僧侣疲劳的双手。中世纪时印刷机尚未发明，要出版一本书，每一个单词的每一个字母都得用手工辛苦的刻出来。从事这项长时间辛苦誊写刻画的僧侣们就开始寻找减少每一个常用字笔画数的方法。虽然“at”这一单词开始写起来很短，但它在文本和文件中频繁出现。中世纪的僧侣们就想到如果能进一步简化它，就可以写起来更快更容易。结果，僧侣们就在“a”四周画了一个圈，从而省却了字母“t”的两个笔划。
